WD My Book Duo RAID1 WARNING!
Вставка
- Опубліковано 29 вер 2024
- I ran into some serious issues with my WD My Book Duo RAID hard drive. It was working perfectly fine but then one day it was unmounted from the desktop and I couldn't see it with Disk Utility. The drive had disappeared from my operating system with no way to access the files. Was it a failed enclosure? Was there some weird WD encryption to blame? Here's what I discovered.

Good info., but you probably could've told us all that in 3-5 mins
He was building suspense broski
damn annoying when they just lengthen this shit
Should have read comments first. I got caught too. Plus it’s for Mac users not PC.
He should apologize
I don't know. I appreciate the troubleshooting and his personal experiences.
Thank you for a very useful, well considered and informative posting. Confirmed my suspicions about exfat.
I have a 12TB mybook duo which was formatted exfat but it went awol so I reformatted it as HFS+j about a week after I got it.
I must agree about their software - reports "errors" and then dumps you, stranded, with nowhere to go.- Tear the thing apart and re-fomrat, with data lost.
The issue isn't exFAT itself. The issue is that Apple does a poor job implementing industry standards, as it wants its customers confined to its walled garden as much as possible. But as the video shows, if you are going to use Apple products, you should probably stick with Apple's internal standards like HFS+, despite its shortcomings, such as the lack of checksums. Linux can read & write HFS & HSF+ volumes, and commercial products like MacDrive for Windows allows Windows systems to also read, write & repair HFS & HSF+ volumes.
Exfat is only for usb thumb drives/flash cards. Its not made to be reliable at all, just simple as possible for portable/low write endurance media.
Hi Stronz, thank you very much for sharing your story. I am on the verge of buying one of these arrays and this is very useful information.
I'm also a Mac user.
Another question: is this system hot-swappable?
+Mario C. Castillion I wouldn't consider it hot swappable. You only want to be moving the drives when something has gone wrong. The ideal and intended use is to leave the pair of drives alone as long as they are working and functional.
Thank you for your fast reply. Appreciate it, man.
I'm ordering this drive for sure.
Keep those very informative videos coming.
Damn - i have the same problem. WD couldn't help me. Houston i have a problem. Can you please come to Berlin and help :) Hopefully a friend can help soon. Thanks for your video
Sorry to break this to you but it's not an exfat issue. These duo enclosures have hardware accelerated encryption. Which is a nice thing. However, if you routinely do a lot of large file transfers, the chip on the board in the enclosure that's responsible for encrypting as it writes to the disks and decrypting as it reads from the disks, will overheat and wearout because there is no heatsink whatsoever on the chipset. As the chip starts to fail, your enclosure or individual disks in the enclosure will dismount sporadically. Furthermore, if the chip overheats during a file transfer, the file might finish transferring but the data will be unreadable. On top of that, due to the fact that each chip has a unique encryption algorithm, if the chip or enclosure fails, you cannot simply remove the discs and read them even in another duo enclosure. All the data will be lost, albeit the disks can be reallocated in a partition manager but again all data is lost.
To make matters worse, even if your data is intact but encrypted and thereby still unreadable, WD will not let you know what the decryption key is that will allow you to recover the data via software decryption. Why would WD not provide that? I can only assume they are sacrificing their current customer's satisfaction for security and also because WD made deals with certain data recovery firms to provide them access to the decryption keys for profit in a croney kinda way.
The good news is, for people who do not do a lot of large file transfers(I'm taking GBs at a time), these enclosures and their encryption chips will last years and years. The easiest way to overheat the encryption chip and eventually kill it is to transfer data to or from the enclosure in TB amounts non stop. That will kill the chip in less than a year.
Good point but are you sure about that? He says that after "recovering" the WD My Book Duo (by reformatting it using HFS+J) he tried to take out the drives from the enclosure and test them on a Mac with a different external enclosure and he could read each of them fine (09:38). Maybe the encryption is optional when configuring the My Book Duo or what you explained only happens on new models (I noticed that this video is 2 years old and your comment is more recent)?
i think he test it in other mybook dou still same type and brand
If it was the chip that got fried, surely it wouldn't have worked again as he says it did?
@@edwardcullen3251 Perhaps the encryption is unique to each enclosure?
I´m working from my WD Duo drive, doing video editing. Will this burn my WD duo? My projects are about 200-300 GB, but once transferred to my DUO I from there.. not transferring anything back and forth so to speak
long ass story. literally could have summed it up in 2 minutes.
you right
I'm glad this was the top comment in my view because I literally had the thought, "This guy sure loves the sound of his voice. Christ... No pun intended."

@@edstar83 irrelevant to the fact that this video didn't need to be as long as it was. guy was just milking watch time
Backup your data! Just cause you’re running in a RAID configuration doesn’t mean you don’t need backups. You still have a single point of failure which would be the enclosure
So you at no point realizing it was on exfat, tried to use a Windows PC to see the drive? Jees, mac users.
@kryptoday exFAT doesn't support journaling, so the filesystem can get corrupted when the drive loses power during a write process. On Windows the file system can be repaired by running `chkdsk X: /f` or `chkdsk X: /r` (with "X" being the volume letter of the affected drive). Windows normally recognizes the corrupted filesystem itself and asks if it should check and repair the affected drive when you plug it in.
As far as I know repairing a corrupted exFAT file system is not possible on other operating systems.
@kryptoday It's because he's an idiot.
Good Video, Good Information
As a long time RAID user with years of experience with failed hard drives, I would recommend that users do the following
1. WD My Book Duos Are Good Units, But Hard Drives Fail. Prepare for failure.
2. RAID1 Is Not a Backup System. All RAID1 does is provide a one disk failure tolerance, e.g., if one disk in the enclosure fails, then the 2nd disk should be recoverable. If the whole enclosure fails or the Mac file structure is unstable, then you are FUBAR.
3. Backup Using the 3-2-1 Rule. Three Backups, two onsite, and one offsite. I find it hard to believe that an IT guy like this uploader only had one, a single copy of his important personal data. That is a rookie mistake. For around $10 per month, many companies offer unlimited cloud storage. Oh, and I have made that mistake too, by the way.
4. Consider Using a NAS for Backup (Network Available Storage). There are some good ones out there, and they utilized your network accessible through your LAN by a Cat5 hooked to your switch or router. RAID0 and Raid1 are both options. Synology is a well accepted brand, but is not easy to set up. Again, a NAS is only part of a backup plan (3-2-1), so one always has four copies of everything.
This is a really good video, well presented and I was impressed by the uploader's ability to problem solve.
Hi Tom, thanks for sharing your knowledge. Which unlimited cloud storage would you recommend?
didn't saw the end of this video... dude, get to the fucking point!!
J B ikr. 15 minutes, had to skip around
I am a CIS-System Administrator, not a bad job but you could have explained it all in about 2-5 minutes
6:20 Just here as a reminder for myself if I ever need to watch this bit again, don't mind me
SMR hard drives are a big problem for backups (even in HFS+J). If you've never heard of the SMR hard drive scandal, do a Google search. It seems that comments on this issue are systematically deleted by the author of the video. Why?
I think I have the same problem, i just switched to mac and my MyBook duo works very well on my PC but it can't mount on my mac
Too much unnecessary talk
Thank you for sharing! I'm glad I found this before I configured my new drive.
THANK YOU! Spent hours with WD chat and DELL support going in circles trying to get my WD MyBook Duo set up. WD chat was USELESS! Watching your video showed me that I needed to download the WD Drive Utilities. The product came with NO INSTRUCTIONS and the online manual was useless. I now have it configured after almost 8 hours of being jerked around. Thank you!
The problem: exFAT does not support journaling.
The fix: Plug the corrupted hard drive in a Windows machine (note the letter the drive gets assigned -> G), open the command line and run
chkdsk G: /f
The solution: Don't use exFAT. If you want cross-platform compatibility, choose NTFS.
EDIT: Just realised that macOS doesn't support NTFS...
Yes it does, you need to buy Paragon NTFS driver.
Hardware failing? Whoa Nelly, wait a minute!
Well I am having this exact issue. Now after watching 15 min video I still have no idea how to recover my files on the WD Duo? Thanks.
TOO MUCH TALK
...but did you try hooking up the drive enclosure to a PC via the Ethernet port? just to see if you could recover (copy/transfer) your files? instead of Mac?
...exFAT is a non-journaling filesystem. In other words there is no way for the file system to recover files if something goes wrong. Jounrnaling filesystems keep certain bits of information about the files in case there is a problem and then an operating system can use that information to recover the files if there is a problem; non-journaling file systems can have certain benefits. IOS is sensitive to problems with exFAT but the data is NEVER lost until you either fiddle around and do the wrong thing or format the drive. The solution is to connect the drive to a windows system and run chkdsk /f (SUPER-RECOMMEND, IN THE EVENT OF ANY PROBLEM WITH DATA ON A HARD DRIVE, TO CLONE THE DRIVE FIRST JUST IN CASE). There is another solution and that is prevent the issue to begin with; likely caused by an improper shutdown (just turned the computer or drive off) or if you aren't aware of that occurring then likely it was a power failure or brief "blip" while you weren't there. I recommend, highly, that you connect anything related to a computer or data to an UPS (uninterruptible power supply). Just remember, the data on a failed drive is never gone until YOU make it gone. Its always so painful watching people who don't know a lot about computers trying to solve bugs and issues but I do have compassion and will do as much to help them as possible...
This just happened to me. Was moving all my files onto a NAS and the WD just died. Got a RAID failure message which now doesn’t show up at all. No utility will recover it.
Hey I've just solved a similar issue! After much research and trying different things, I removed one of the hard drives and booted the My Book Duo with only 1 hard disk and plugged into my PC. It now had 2 red lights (a flashing power red light and a solid HD red light on the missing drive) but it was totally recognized by my PC and I could access all files and info! If you are having this issue this is worth a try!
Great to know for those with access to a PC. Thanks for the tip!
After your suggestion I tried the same thing (removing 1 HD) and plugged it into my mac and it worked! Thank you!!
@@matthewherrmann474 yeahh!!!!
Excellent video! Saved for future reference!
When you were trying to recover the data, did you try to access the raid on a Windows PC?
I am familiar with this problem. Amazingly I came up with a super easy solution. I connected the hard drives to a Windows PC which immediately recognized that one of the drives had an error and offered me to scan and fix it. After clicking on "Fix it" button the drive was scanned and corrected and started working again. I connected it back to my MacBook Pro it was working. This happened at least 3 times and now watching your video I am realizing that exFat is probable cause. Thank you, I will reformat them too
Thanks because I was about to use ex-fat until I listened to your story.
It's great you figured out the problem but you wouldn't have lost the data had you just tried to plug the drive into a windows pc and then format it once you retrieved the data.
You think he would have recovered for sure?
I don't have a Mac however I do have a MyCloud device with RAID, however I found your video very helpful. Ignore these negative comments about length of your video.
Thanks!
Thank you for the Tipp, but you could have shortened this a bit. Tx so much!
This happened to me a few months ago and I landed in this video. My My Book Duo was also exfat. Just today, I decided to change the power source... I took my cord from my LED production lights and bam! It works again. I think it needed more power, it's the only thing I can think of.
Anyone know how to recover files from a Seagate 1tb back up drive? It was originally formatted with 2011 MacBook Air using ext journal ( might be encrypted), & there was a Time Machine back up on it. I bought a 2014/15 MacBook Pro but never used the backup. Then I upgraded to a 2021 MacBook Pro m1, & plugged in the drive, & it’s not reading the hard drive in disk utility. I plugged it in the 2015 Mac it shows I’m using 980gb but I can’t read anything…. Any reasons why or how this can be solved?
This tittle is super misleading and should be changed to "Formatting Warning" all drives will have this issue, mac don't play well with anything formatted FAT or exFAT (basically anything not formatted NTFS or Mac Journaled). If you were on PC you might have been able to recover the data. Here i am looking for reviews on this drive and i see this tittle and the issue was just ignorant user error, it bothered me so much im making a comment which i rarely do. In conclusion anything but NTFS or Mac Journaled you will always have issues with your drives.
I had the same problem back to 2010, when i formatting FAT32 for my Mac computer. if you keep working on mac with FAT32 hard disk, power on all the time, never eject the disk, one day you will loss your data. It also have a symptom before disk fail. unexpected eject disk often on mac. and then both Mac and Windows computer cant organize the hard disk. i think the best way to working on FAT or exFAT format hard disk is transfer your data between Window and Mac and then eject properly, power off immediately.
Don't 100% trust hard drive, even a raid 0/1's hard drive, always have a 2nd physical backup hard drive device and make sure backups are frequently done from Raid 1 hard drive to 2nd back up Hard drive.
Indeed. Whilst RAID mirroring does give some level of data protection (i.e. one drive can fail), it's more about maintaining up-time and improving performance. It does not negate the need for a separate backup. If the enclosure electronics fail, then you're on dodgy ground as to whether those disks can be imported into another system. RAID controllers tend to bespoke solutions. It's one (small) advantage of Windows software RAID - you can stick the disks in almost any other Windows system and import the array
I'm curious to know if you now put one working drive (with hfs+) out of you WD book into a dock, if you can read the data ?
I think it would be completely useless to have 2 drives, when the case brakes, you can no longer acces any of the drives! I would't be to happy if I had to buy a complete new WD book (for as long as they are available!) to acces the data on a broken device.
If so, do you know of any other options ? I'm thinking to attach 2 drives (sata to usb3 enclosure) to an "old" imac and let MacOs do the raid1, but even then I'm not sure what happens if one drive fails.
Edit: Thanks for the warning!
Everyone is talking about exFAT (in isolation) but, given the "it's apple's way or the highway" nature apple devices I suspect it is far more likely to be an apple problem with the apple devices corrupting exFAT (specifically) formats.
i'm guessing that there are millions of Mybook Duos out there happily using exFAT with other OSs. It's just with apple that the incompatibility shows up.
It is interesting that someone else here has commented how their Windows PC identified the error and fixed it. This implies to me that Apple's inability (unwillingness?) to "play nice" with anything not proprietry is at the heart of this. So the moral of the story for me is.....
Good video and very well presented. Well done for potentially saving others a lot of grief.
extfat was originally designed by microsoft for use with removable digital camera SD media, which is where it performs best, but using it with raid disk arrays and managed by WD raid controllers and related firmware shows that, in this instance extfat should not have been certified as ready for enterprise use scenarios.
The reason why you couldn't read the files in the hard drives is because WD Mybook Live duo hard drives are formatted in Linux.
Raid is Not a backup !
I hate those fairy elvish user stories. Whole 15 minutes of crying without any technical details. No results. Nothing valuable in the whole video.
Dude, don't use proprietary RAID controllers, you'll have even worse problems, with no chance to recover your files.All the mainstream OS can create their own software raids, even stupid windows, and the known format is what can guarantee you the possibility to recover.
did you try plugin it into a windows PC? Maybe it would have let you recover EXFAT?
Did you try to use a recovery software after reformatting your drive from EXFAT to HFS+J ?
Really interesting video - I have a WD MyCloud EX2 fitted with 2 x 8tb Seagate Ironwolf Pro HDDs in a Windows 11 environment.
HD1 started suffering a solid red light which went away after a re-boot but came back again a day or so later. Thinking it was a HDD issue I RMA'd the drive to Seagate and a week after installing the replacement (and rebuilding RAID 1 YAWN) same thing. Now I'm sure it's not the HDD and I think it's a false flag which would be a firmware problem. I've made a couple of local adjustments by powering the external fan I have for extra cooling separately rather than using the USB socket of the unit - without it the HDDs get quite warm even when not transferring data. The other thing I've done is disable drive sleep to see if that helps - it may also help my TV to keep the NAS connected as it occasionally loses the unit's media server.
Will wait and see but everything is backed up elsewhere and so I may just continue running the NAS even if the red light comes back. I went with WD as i thought it was a solid brand - maybe Synology would have been a better option.
Great Video because i was looking at a 44 TB western digital to buy and even though this video is old it still relates to my potential purchase. Thank you very much👊🏻👊🏻
Dang!! I did exactly what you did. I should have watched this 3 years ago. Great video, thank you much.
Running `chkdsk X: /f` or `chkdsk X: /r` (with "X" being the volume letter of the affected drive) on Windows would have most likely repaired the corrupted file system.
It's a shame exFAT doesn't support journaling.
You could have simply plugged it into a Windows PC system and chances are that the data would have been there, you may have had to run checkdisk, or scandisk but it would have given you your data back.
U suck
the annoying part of WD my book product is, the drives are encrypt. if the case is broken, you can not use drives in other PC. similarly to upgrading old drive with new one. old drive is encrypted.
The network card in my enclosure died, left me with 8TB of data I couldn't access and I've had to spend days using linux readers to try and offload the data to random harddrives i have laying around. It's absolutely rediculous that you can't just replace the enclosure. Western Digital customer support have been horrific
That happened with a Lacie drive that was xfat and I tried everything and ended up going into Terminal to mount the drive, and after trying several different ways in terminal it finally worked.
There's drivers available for Windows 11 to be able to read and write Mac formatted drives.
So shortly put:
WD disk drives enforces encryption even if you do not enable it, and so on if your hardware driving the RAID dies, so does the encryption key and data can't be recovered.
This is the exactly same thing that has been since 90's, DO NOT USE MOTHERBOARDS RAID FUNCTIONALITY! In fact, DO NOT USE HARDWARE RAID FUNCTIONS (unless very specifically confirmed to be very strictly recoverable without hardware).
Want the easy solution? Buy harddrives as such, get a USB dock and store data first to one drive. Then run a syncronization for another drive. Linux software RAID's is OS level, works perfectly and doesn't cause trouble. Microsoft might offer good option, don't know about OS X itself.
But just forget all the enclosures etc that has hardware RAID.
Interesting video. I’ve had a Mac for ten years with one of these storing my photos and music. Now I have a windows machine and wanted to use with that but I had the drive formatted as Mac OS extended and the pc can’t read it…plus it’s an old thunderbolt2 version which (of course) windows doesn’t have anyway. Okay so anyway, I’m in the process of copying the files off it to then reformat and had assumed I would have to use exfat as “the other option” but a) not gonna do that now and b) for windows I’d want ntfs. Was thinking of just getting a newer one anyway to get away from the old thunderbolt stuff - if I do then I’ll avoid exfat. And maybe also use some cloud backup as well!
RAID IS NOT A BACK UP...WAAAAAAAAAAAAAAAAAKE UP !!!
One very important thing to note, RAID 1 is not a backup in and of itself. Although RAID writes data to two disks simultaneously, it is not a backup. If your operating system or software, rather than the hard disk, corrupts your data, this corrupted data is sent to both disks and simultaneously corrupts both drives.
Raid 1 is useful ONLY for redundancy, and Your work and yoru shitty mac computer or network do not need redundancy........if You will ever set up a server for Your work then you will understand what redundancy is about, and STILL you wil need to back up ur work somehwere else.
Thank you for this story. I have a similar experience with external SSD. I formated it to exFat use it on Mac and when I plug it to PC error popup shows that the disk needs to be checked. I did the test (it takes a few seconds) and when it finished one of my folder (35GB of video footage) was gone. I tried to save the data but without luck. One guy from the data recovery company tells me that exFat isn't very reliable file system. It brings both worlds (Mac and PC) together but neither works 100%.
Never use exFAT for storing important data. It IS NOT a hi-performance file system. It is an extension to FAT32 which is also not a hi-performance file system. The purpose of exFAT's existence is for things like USB thumb drives to be able to handle extremely long filenames, very large files (measured in PetaBytes instead of FAT32's 4 GB limit) and be cross-compatible. Almost any operating system you may come across can read and write exFAT or have exFAT support added. All recent (last decade or more) Linux, macOS, and Windows systems can read and write exFAT. The only reason it is an option on these drive systems is for cross-compatibility. But then your losing journaling and other safety features that are part of HPFS, HPFS+J, NTFS (Windows, but most Linux systems and read and write to NTFS drives). If NTFS was supported natively on macOS (there are options but none are native) then NFTS would be a great option for this drive system where compatibility between Mac and Windows (and Linux) is necessary.
I also highly doubt much work and testing was put into the exFAT support on this drive system. At the time of it's introduction (and even now in many places) if you own a drive like this you were very unlikely to also have a Windows machine that you needed to support with the same drive setup. The feature is of dubious need in any case. If you need to share files with a Windows machine attach an FAT formatted (FAT32 or exFAT) USB-3 drive to a USB-3 port and copy those files to the USB drive. Then give the USB drive to the Windows machine. If you need a RAID-1 setup for a Windows system get one designed for Windows so you can format it with NTFS. For hi-performance and safety always use NTFS on Windows systems when available. With the exception of thumb or other memory based drives (SDcard, etc.). For those use exFAT for sharing. Or NTFS if you don't like the idea of sharing with other operating systems other than Linux.
I performed a soft reboot on mine and my shares no longer appear on the web console. oddly, the share i created on the attached usb drive does still appear.
im gonna look for fix, or attempt disk recovery.
I had the same issue, and same result research I was only able to get some data back using test disk/photorec my system was Windows. I will avoid exfat
WAYYYYYYY TOO MUCH TALKING. Are you insane?!

End of video
Hey, thank you for the Video. I have a problem and maybe you can help me. My wife has two of these My Book 8T Raid. One has Green HDD´s and one Red HDD´s. Now after some years on of the Green HDD´s is not waking up. So we might have to replace it. The questions is, can i replace a Green HDD with a Red HDD ? because the Red ones are only half the price. Thank you ! (we have the thunderbolt version)
Sorry but i have to mention an Asshole advice, Raid is NO Backup, use a Raid for your work that you are able to work without time loss if a drive fails but you need an extra backup on a different drive or in a cloud solution. For safety reasons 3 copies of your data and 2 different techniques are needed 1 Drive+ 1 Cloud or 1 Drive+1 Nas. Never trust a raid one with all your data on as being a Backup, two drives can fail sometimes, or your enclosure fails, or it gets stolen or is going up in flames. Even the Big Data Centers have Raid 6 or 10 Setups where multiple drives can fail and if all of them will fail they have a backup of everything on another server in another building in another Raid 6 or 10
Ex-FAT is only used for transferring files ( one & done ) from a Windows file system to a Mac IOS
I found one of these at work. I run a small business and someone turned this in after they seen the WD My Book Duo fall out of someones car. I don't have any security footage to return to owner. What can I do with this? lol
As a user of macs for 30 years it’s embarrassing that apple’s current customer base of “pro users” (lmao) have no clue about the technology they are using. You lost your data and still make no mention for your viewers of how this could have been easily resolved even though a simple solution has been pointed out to you by people in the comments section. A simple video update could stop the poor “pro users” from unnecessary drive formats and data loss.
I was curious, do you think you could have got your footage back if you hooked it up to a windows computer sense it was cross capable ?
WTF I cannot choose NTFS for RAID1 option? I get the ExFAT crap off these types of drives as soon as I unpack it.
That information would have fit comfortably into a 1 min video. :-) But thanks for the heads up!
I'm so glad I came across this video! Sorry for the loss of your files. I would be devastated if I lost my personal projects :(
Just say right from the start that you couldn't find a solution bonehead. People are trying to figure out how to get their files back, not delete everything and start over.
I lost all my data after the drive encloseure (not the drive) failed as WD encrypted them. HUGE FAIL ON WD's part.
Great info. Thanks for the tip. I'm gonna use 2 of these on a Windows machine so I'll probably reformat to NTFS instead of using the DEFAULT exFAT format these ship with. I dunno if exFAT is as unreliable on Win as MacOS, but no reason to take a chance. Thx again.
What happened? Any problems? Did you finally use NTFS? I'd appreciate a lot your experience!
@@intheskyaerials Sorry, but I ended up buying a different version of the WD drive and "shucked" the drives so my experience prob won't help U, since I'm using my WD drives in an unintended manner. But yes, I did format my drives as NTFS and haven't had any issues. But again, I am NOT using them inside their USB enclosures as they're intended to be used. I shucked my drives & added them to my server. I've bought 7x 6-10TB WD Elements versions instead of the My Book Duo featured in this video. I went with the Elements version b/c they are better for shucking as they don't include any drive encryption hardware or software on the USB host adapter that might complicate the shucking process.
@@EricS-uf9mv I see.. well thanks anyway and I'm glad that you found a solution that worked for you!
Using one of these devices is good, but YOU HAVE TO BACKUP THE RAID DEVICE ITSELF. I believe RAID devices are more meant for convenience of use than full blown backup solutions. You can back them up to an attached USB device, a cloud backup, or another My Cloud device (assuming your device supports these options).
Also, rather than buying many of these MyBook Duos, you could get bigger My Cloud devices, like a PR4100 with 32TB, etc. Then you could run two of them and back them up to each other, therefore you would have only two devices instead of 12, but they would still be redundant to each other. It might makes things simpler.
Side note: I'm a network guy, I would have been interested if you looked in your router or used a program like PingInfoView to ping your whole network subnet, to see if that MyBookDuo was still online but at a different IP or just locked up or whatever. Sounds like it was just down, given your story, but I would have also checked that.
Lastly, I was wondering if there is a way to check what type of file format was used in setting up the system? I have a My Cloud Mirror and I can't remember what file format I selected... if I was even given that option... because honestly I don't remember that part. I just setup a My Cloud PR4100 yesterday and don't remember that option with that device either. Maybe this is more related to the MyBook Duo's?
Exactly right, RAID is not a backup. If data is valuable, back it up.
Hey, would you sell one of your enclusres to me? My enclosure died and is not produces anymore. I cannot access my data.
The problem is you format drive to be exFAT by using Mac OS. If you format the drive to be exFAT with Windows OS it would be fine. It is kinda funky when using Mac to do non Mac stuffs.
I don't want to lose data as a learning experience.
long story short he had RAID 1 + exFAT but managed to corrupt them both simultaneously from incorrect power down procedure or the mac not having %100 robust drivers for exFAT. I corrupt my exFAT all the time but I am always able to recover by rebooting and powering down correctly. You just can't use an operating system that is not compatible with the drive controller (the external enclosure) you used for the exFAT drive.
How about the My Book Duo Cloud, would you recommend that?
Just took delivery of one.
So exfat is ok if I use Windows 10. In fact is it the only option.
Always remember: RAID is not backup, it's resiliency. When using RAID 1 and onwards it's about being able to take drive failure without losing the dataset, it won't help you if you delete a file or if it becomes corrupt or you wish to revert to a prior version of a file.
alpha xion Would you care to suggest a backup solution rather than patronising those with less knowledge than you then?
Of course RAID is a backup, what nonsense.
@@daltonrandall4348 It's not a backup, largely because there's no historical data. If the data in your RAID array is corrupted you've lost that data. It is purely for resiliency should any drives in your array fail.
I hope you're not IT for where you work, because if you rely on RAID as a backup you have no backup.
@@alphaxion That's like saying if a nuclear bomb goes off at the super secure bank vault where you've stored your backup, you've lost that data. Of course if the backup gets destroyed you lose the backup... you're stating the obvious.
i need help i have 20 tb hard dirive and both unallocated i need help pls
I use backblaze to backup to the cloud and use these for local storage
I wish I had seen this video last year. Came here because two of my My Book Duos mysteriously became permanently invisible a couple months after formatting as ExFat... :'(
Maybe just make it to have an drive letter to show up, in Windows. ?
Did you check Finde> Preferences if the option Share>Connected Servers and Devices>External Disks were both ticked on? If these were not ticked on, it could prevent you from seen the drive on the desktop. Another thing you could have done, was to renew your DHCP under System Preferences>Network>Advanced>TCP/IP and clicked the button Renew DHCP Lease.
You look like Jesus
Lol, the legendary Jesus of Nazareth would not appear to be so European. Jesus would have been a darker-skinned Middle Eastern Jew according to the New Testament. The notion of white Jesus is just fan fiction.
And you never tried the "broken" HDD on a Windows PC, right?
C0L0RMAN spot on!!! Btw stay away from interior mac filesystems and downlevel windows compatible filesystems like extfat. Ntfs is the best. Ifag!!!
as someone who uses mac's and windows, and have had problems with exfat drives in mac after like an accidental pull out etc, usually they load up straight away in windows, run checkdsk on them and then they work fine on the mac again
@willy wonder
ntfs is a dumpsterfire, that we (inc me) only use, because microsoft criminally refused to support BETTER file systems like ext4 by default or in general, as one has to remember, that microsft sees gnu + linux as a disease, they want to irradiate, hence the war on any open good stuff like ext4.
NTFS is just all we got, no reason to cheer on the prison bars with the goal to forget who put u there and the goal to forget the freedom and better shit, that has been held from u.....
and let's not even talk about how ZFS type file systems should be the true goal, because of checksums and what not.
@@maxtorsumitomo6249 You're an idiot. NTFS was stolen from DEC and is ancient.
i have a problem with western, lost everything cause of a bad enclosure, the problem is they encrypt the data and its board specific so you cant swap the board or take the disk out, be sure your data is not encrypted in hardware level before you lose everything
Did you try to read the xFAT on a Windows machine?
Did you try connecting the drive to a windows PC? I've had similar issues and used Ubuntu and the drives mount just fine. Note (I don't think Ubuntu supports exfat) I gave up too soon after multiple attempts with my MacBook. WD hfs+ NTFS and EXfat drives have done this to me.
Also after more research I've found that if you wait 30 minutes are more with it connected to our macs. The EXfat drive eventually mounts as a read only drive. This happens after it fails multiple times to mount as a read and write drive in the background. I think mine HFS+ was due to unplugging before ejecting the drives. Not by me but sometimes I would notice when coming back to my MacBook I'd see the improper ejection warning message. Note I don't recommend using non powered USB hubs.
As for the NTFS drive failing. I'm in the same boat for a reason why. Maybe software?? Let me explain.
I know Ubuntu worked like a charm. So, I just recently tried uninstalling all WD software. I still couldn't get the NTFS drive to mount, except with Ubuntu. I did a fresh Mac OS install then I connected the drive and the NTFS drive mounted immediately on my mack OS sierra.
Since My recent experience, I will not be using WD software again.
hey stronz, sorry to hear about your troubles. Next time if you do run into failures you can run a live cd ( that means not installing it, but just to use the os ) of ubuntu, fedora, or some other linux distro, and use root and file manager nautilus. chances are Linux will see it. this has happened to me in the past.
Thanks for the tip! These files were not that important so giving up was ultimately the easiest solution but if it had been professional work I would have definitely tried every obscure method for recovery possible.
Why are is no one using Synology system ?
because they use intel dying atom chips, because they use proprietary psus and overall system, hard to service/hard to repair.
no proper ZFS support (correct me if i'm wrong here).
ZFS is what u want to avoid corruption and data loss, unlike basic raid 5/6 hardware or software raid 5/6.
price and upgradability!
the cheapest synology nas with 8 bays costs 700 euros!!! without drives of course.
for that money u can build your own ZFS file server with the capability to grow even far beyond 8 bays later on.
and it has the advantage of running ZFS instead of shity old raid 5/6.
sooooooooo as u can see there are many reasons.
how did you was able to reformat the drives if your pc couldn't see them? thx
I have the same question too, how can you reformat a disk that does not show on your mac
Loooong story short... Don't format your drives as ExFat with RAID1. Good information. 15 minutes too long though.
Only exFAT is the problem. He could have easily repaired the corrupted file system on Windows though.
I had the same issue on my pc. Suddenly the MyBook was gone ( NTFS Format). I plugged out the disk to see if there is still something on it. No luck. After plugin´m in agian, i changed cables, power adapter and usb port. And then it runs again. No problems.
Thanks for the information Great video ;)
You can buy something like this for local backups, but ALWAYS have an off-site backup. This in combo with IDRIVE, MOZY or Spider Oak can be a powerful and cost effective personal solution. For your office, it's dangerous to leave company data backups accessible locally. Backups to an enterprise solution can protect against ransomware and provide you a cloud out solution to ensure the data is off-site. A company that cannot recover their data in a disaster will suffer tremendously or go out of business outright. Tivoli Storage Manager, Commvault, Netbackup all have solutions. HP and IBM have server / storage that when bought together can provide a powerful solution locally and the backup software usually has a cloud out option where the data can be copied to the cloud in a secure way. Or get a data domain behind the IBM / HP servers. Perhaps worth a look.
Salut, je suis après car je suis en grosse galère ! Je suis photographe et j'ai mon my book duo qui à disparu d'un coup de mon folder ! (sur mac donc) Je pensais qu'en ayant choisi le mode RAID 1, cela m'aurait permis de pouvoir connecter au moins un des deux DD directement sans le raid en SATA pour pouvoir récupérer mes fichier facilement! Mais non aucun des deux DD n'apparaît sur Mac ou Windows... Est ce que quelqu'un sait si c'est normal? Que un DD crame ok mais les deux en même temps ?! Possible? Enfin je ne vois pas trop l'utilité de faire un RAID si pour ne pas pouvoir récupérer ses fichiers ensuite... Le pire c'est que l'application WD Drive utilities me dit que tout vas bien ! J'ai donc fait un scan avec Wondershare recoverit sur mon mac où j'arrive à voir mes photos et dossiers mais une fois que je les récupères elles sont illisibles ... Je vais maintenant passer par un pc et faire la meme manip pour voir si les photos seront lisibles après la récup... Je l'espère... Si quelqu'un à l'explication à mon problème et une solution je suis preneur ! :)
Merci !
Same problem here! Yes, it's ex-fat!
Does anyone know what is the format of these NAS Drive's hard drives? I purchased a new 4TB hard drive by Seagate, but when I put that inside this WD MyBook Duo enclosure, it never sees this new drive. I tried taking out both and only put the new one, still a standing yellow light at front. I have tried to format the drive in all know formats, like exFat32, FAT32, NTFS, etc, etc, but no use. Please help guys.
WD is not a disc neutral NAS, MyBook Duo only supports WD hard disk drives. In fact you are held to ransom with nearly all WD products as they only support their own HDD. For the MyBook Dup WD RED Plus is the recommended way to go.
