75% done, and everything that's found (5 clusters) contain data from the game Pandemonium. Also, while not scanning the physical part of the HD, it find problems in D3Dsomething.dll, in a Sysbackup folder. Anyways, still scanning...
Edit: WOOHOO! Guess which comp I'm on

My guess is that this HD's been getting eenieweenie damages from all the powerfailures the messed-up electricity in this street's causing (420V once, when an electrician was only measuring things? Fried dad's screen, it did >_> ) and decided to notice it when I started it up (although I shut it off like it should be done... no power failures or something like that in the last session before it noticed the damage)
