Thank you essenbe; you said it better than I did.

I'm thinking that the flash drive was in the process of doing something and stopped with hibernation before it was done; leaving the file corrupted.
Can hibernation do such a thing or will it wait for the process to complete before going into hibernation?

Well, windows does not wait on writing files when shutting down or restarting the pc, so I am thinking hibernate does not either.

Hibernate saves what you currently have open on disk, then turns off. But I think telling the pc to hibernate with a flashdrive in is a bad idea in general. I am confident it would attempt to save the state and screw things up in doing so.

Thanks again for the responses, everyone. The drive was a Silicon Power 64.

To the best of my knowledge. Flash drives have no cache, so there should be no damage if power was removed from the drive by Windows. Perhaps it was simply time for the drive to die. Whatever happened, I believe this brings to the forefront, the importance of backing up all of your data to more than 2 places. If you care about your data, it is important to back it up, and have it in more than 2 places. For all hard drives of any kind, it is not a question of if it will die, but a question of when it will die.
