I have encrypted an external hard disk (the entire drive). I have been using the drive without a problem via Truecrypt for about a year. When I plug in my external hard drive Windows Explorer sees it as drive W:, but when I double click it I get "please insert a disk into drive W". Normally I could double click the drive before launching Truecrypt and see my ~2TB encrypted file.
When I launch Truecrypt, drive W: is not visible. If I unplug the drive, volume W instantly appears within Truecrypt and disappears within Windows Explorer. Since I cannot see the drive within Truecrypt I'm unable to get to any of the files on the drive. I have tried rebooting, remapping the drive letter, I've tried another PC and each time the same result occurs (the drive doesn't show up in Truecrypt). I have access to a Windows and Linux box if it helps but primarily use the drive on Windows (at work).
Any advice for troubleshooting this one?
