Mounting a Naked Floppy and recovering data from 30 year-old diskette

- For those curious about floppy media, here's a demonstration of a floppy disk running outside of it's jacket as well as a demonstration of how robust this storage media really is.
I'm surprised UA-cam didn't freak out at the "Mounting a naked..." Phrase in your video title
The only disks I ever used that could be ‘flipped over’, were the 3” ones used in the Amstrad CPC6128.
It’s true that a 5.25” floppy disk could be turned over on a single sided drive that only read one side but it was far too much hassle and the disk was likely to fail at some point. Personal experience.
Running a disk without its jacket is a disaster waiting to happen. The cookie just isn’t designed to operate like that.
Did you even try running Jumpman to see if it wasn't just copy protected there and might actually _need_ that error sector in order to verify the copy protection? Maybe instead of using a copier that does each item as separate files, try using an image copier: one that just copies a disk exactly, sector by sector/bit by bit, regardless of errors, etc.?
"How do you recover data off of a disk?"
You don't. You recover data _from_ it without wanting it to also get removed from the disk in the process.
I suppose that would be called a "Destructive Read Procedure". 🙂
You might wanna try reinserting the disk to its jacket without getting your fingerprints on it.
20 Years ago. More now. I did the same thing. Remove from sleeve. Clean crapola off of it. Cross fingers. Copied data once to hard drive. That was it. Show is over. Got the files. Disk never read again.
Which drive was O:?
SS/DS ; needs a snapper.. to make a second hole.. !
Why would you rasor the disk's --"envelope"-- _jacket_ to remove the disk when you can do more easily by simply snapping the edge-folds off from the main surface?
The jacket is so atrophied with time that flexing it would be to shatter it. I've discovered that feature of old jackets the hard way. Even so, you can see that the razor made a jagged cut.
Was the disk the only thing that was naked?
A gentleman never asks and a lady never tells. ;-)
Using a grease weasel might get you something better for recovery if it was actually something important but obviously this is just a thing to try.
I do have a grease weasel, to produce disks for vintage computers. Most floppy controllers for the PC are unable to produce an FM (Single-density) disk, so the weasel is my go-to in those cases. Prior to getting weasel I was using a PC and various vintage tools to produce vintage disks from images so long as they were double-density.
You are right. Were this a vital disk, my first step after cleaning it would be to image it a few times using the flux reader, THEN try file-level recovery.
@@Technoid_Mutant I've only really used mine to image some cross format 3.5" disks from a magazine here in the UK that I thought were interesting. I was always fascinated as a kid how they made disks that could be read on a PC (IBM compatible as they were called at the time), Atari ST and Amiga as a native format on each one with different content.
"Brown in color."
As opposed to what: "brown in shape"? "Brown in... number"? Why not just _"brown"?_
Military reference. for example my favorite MRE candy bar was "Bar, Candy, Type 1, Style 3...... It was like a Scor bar but with toffee already in bits.
@@Technoid_Mutant: Maybe what you said in this second reply could make sense as some kind of military reference of sorts, but "brown in color" doesn't. You totally missed my questions about what a color word like "brown" could possibly refer to besides exactly that: a color."
"Brown in color" doesn't make sense, because it's a redundancy.
