I don't share a console with anyone so i don't have the issue of 'Save Sharing'
Most of the time i lose saves is either to my own mistakes or the system messing with me.
The most recent occurance of this was when i was playing Republic Commando. I accidently walked off of a bridge and died- i thought it wasn't a problem since it had autosaved just before. I select the 'Load Last Save function' and it takes me back to when i last last saved several levels before. I try to load the autosave, but it saved over that when i reloaded the save.
