I currently have three external USB drives which I'll call 1, 2 and 3. I can only connect two of them at one time because my laptop has a limited number of USB ports.

So. Last night when I shut the computer down with hard drives 1 and 3 connected, everything was hunky dory. This morning before switching the laptop on, I unplugged drive 1 and plugged in drive 2 and then switched on. When Windows booted, I opened drive 2 in explorer and it showed the label and file system of drive 1. I couldn't access any files. It kept throwing up errors about the recycle bin being corrupt.

Maybe I should have unplugged the drive and tried reconnecting it but instead I started a CHKDSK /R operation which is now going to take 20 hours to complete.

Any ideas as to what happened? I no longer trust that drive anymore so I'm going to have to use it as a temp working drive instead of holding important data. BUT was it Windows itself at fault and the drive is fine or what?
 
i assume you turned the PC off, then turned it back on with only the problem drive attached before you started this chkdsk?
 
Got another PC you can connect them to just to check it isn't some Windows caching bug of some description?

I have but I haven't tried it.

No, I just went straight to CHKDSK. I got fed up after a couple of hours and killed the process though. The file system seems OK bar for only 2 files out of 2000 or so that are corrupted. I deleted the recycle bin using the RD command and that final error has been sorted.

So it's just a case now of going through and copying all the files off on to another drive so I can do a reformat.

It just seems totally bizarre as to how Windows saw the file system of another drive though when it wasn't even plugged in. But as you say, it could be a caching issue. And the drives are all exactly the same type (so presumably have the same disk ID or something).
 
Yeah, I've never had problems before when I've removed them using the little add/remove device thing in the system tray. I'll go back to using this method again.
