I played several hours of Skyrim today until I died and the game greeted me with the message "The save file is corrupt and cannot be loaded." after loading.
This happens whenever I try to load one of the last 7 or 8 of my safe games. Older ones do work, so my character is safe, but I am not very pleased that all my quests from the last day are lost. I took a look at the safe games and they have the same size as the working ones (about 11MB).
I have no idea what could have caused this issue. Since it happened first while I was ingame I am pretty sure that it was no update that broke some safe games. It is also not based on the area I saved in, because safe games of different areas are effected.
When I create a new safe game, I can load it without a problem. Only those 7 or 8 safe games are broken. How should I try to fix this? Is there a recovery tool or is this a known issue? Google didn't bring anything useful up.

Assuming that you are using Steam on the PC, you can try verifying and repairing the locally installed files.
If this doesn't help you, you could also try checking for errors on your hard disk using Scan Disk, in the event that you have some file corruption. This may or may not recover the damaged files but it's worth a shot.
There are two ways to access Scan Disk. I'm going to assume that you are using Windows 7 and that your save files are on the C: drive, if not, enter the drive letter that the files are on. Steps will vary slightly for Windows XP / Vista.
