Guess the topic title explains everythig...could you people please explain me how is it possible and how do i recuperate the missing data. Its unucceptable a bug like this...latest updat has been applied on the 14/1/2013 and its 108 MB and the version its 2.05.

This is ridiculous....

As I recall it, if you run on Autosave, it'll save over your existing data. That should be turned off. But I've also heard and read about people who had their entire save files go missing.....So that one is harder to fix..

Don't have much to go on except that start by uninstalling and reinstalling the Skyrim Game Data (not Save Data), then perform the PS3 file system restore. Haven't done it myself, but I hope this link provides some info to this:

Hope it helps.

Thanks atrox and yes, i have lost the entire skyrim saving data with autosave turned off so its a bug...right now i am thinking of getting out the hd, attach it to an external box for pc, connect it to my windows computer and run a recovery program for deleted data because i am pretty sure it only deleted the indexing without re writing on it. Hopefully the fs is compatible with the program...otherwise i do not think there is anything else could work. If it doesnt work i will try the method you have posted. Tnx again!!!
