I was about to close the video in the first 3 seconds because of the computer voice but I'm glad I didn't, it's a great summary. Good vid!

6:22 40 pin cable allows 2 hdds on one cable too. Remember Master/Slave/Cable Select Jumpers on Devices. 80 pin cable allows faster communications (UDMA...).

Hello @michaelk.6976,
Thanks for your comment.
Yes, we can connect two devices with a single IDE cable. But it depends on how many connectors the cable has. If it has two connectors, you can attach one device. If it has three connectors, you can attach two devices using jumpers. I mentioned the two-connector cable as the 40-pin cable and the three-connector cable as the 80-pin cable.
So far as pins are concerned, all IDE cables are 40 pins. UDMA cables are 80 wires. The additional 40 wires are ground wires that help to keep the signal cleaner. The difference is in speed/standards. 80-way/pin cables are for ATA 66 and higher speeds, ie HDD. 40-way/pin cables and for ATA 33, ie DVD/CD.
To attach two devices with a single cable, you need a three-connector cable. One connector connects to the IDE slot on the motherboard, the second connects to the first IDE device, and the third connects to the second.
