[QUOTE="Alexdr, post: 632165, member: 62084"] Well, I decided to run ddrescue from parted magic and back up most everything. 31 MB of possibly bad (I ran it so that it only tried once), with 1.1 MB of actually known bad sectors. It's been backed up to my 3TB hard drive. I then proceeded to use DDRUtility in order to deduce which files were bad. What was striking was that only the following were bad: -am image for a game file in Program Files (x86) -a temp .wav file from CamStudio -Some image files (the primary ones affected) -A couple videos -A PDF -A data file from a game -A weird one: data from the Journal -And one which says Inode none File none. Based off of what the log file says, this is fine, this means those bad sectors had no data allocated to them. What is surprising now is, why TestDisk found no bootable partition etc., when the bad sectors seem to be restricted to my files (except for the Journal one). Since I didn't retry on reading from the disc, I think it counted the entire 31 MB as bad, thus there are 66727 bad sectors (529 not allocated) listed in the log file. When I look at DDRViewer it doesn't look like much, but I guess I'll need a new hard drive soon. I could probably get it to run if I ran chkdsk /R, however I'm confused as to whether or not it destroys my data. Just to clarify, these are the only files with a "striking look" that have bad sectors, i.e. the only ones which aren't my personal files or in unallocated locations: ########################################################## ########## Files in group StartSector=1265289721 EndSector=1265289726 ########## Inode 87652 File /$Extend/$UsnJrnl/$DATA($J) ########################################################## ########## Files in group StartSector=1265289730 EndSector=1265289734 ########## Inode 87652 File /$Extend/$UsnJrnl/$DATA($J) Also, since the rescue log yields: # pos size status 0x00000000 0x2C228EE000 + It follows that the boot sector shouldn't have been affected by any bad sector corruption. Thus, I can't for the life of me guess why, at the very beginning, the laptop didn't just turn on like usual (before I started messing with it. Well, I guess before I started messing with it recovery tools appeared, but why did the BSOD occur still?, i.e. the UNMOUNTABLE_BOOT_VOLUME). [/QUOTE]
