I am using Windows 7 Pro. I did an upgrade this morning and when the desktop restarted, I lost an entire external drive. It showed the drive letter, but told me that in order to use the drive, I would have to reformat it.
I tried the same drive in a Vista laptop with the same results.
What happened and how can I fix this?
Pardon me for being skeptical (Vista user), but is this going to happen again?
