I just got back from vacation, and I had left my laptop locked. When I returned the laptop had rebooted, and I had to log back in.
When I did, I noticed that a file that I use a lot (my KeePass database file) was missing. I have no idea where it went, or how. I did not notice any other files missing.
I had a backup of the file (Thank you JungleDisk/EC2) but I am just curious as to what happened. Should I be worried about hard drive corruption?
