No, after several days chkdsk did not finish, so I powered off and replaced the HDD, reinstalled everything. Now I'm trying to decide whether the data on the old drive is worth the cost of (attempted) recovery, and I'm thinking of buying Steve Gibson's Spinrite software. I've been listening to Gibson's Security Now podcast for a long time and I've heard lots of "magic bullet" type stories about Spinrite's recovery capabilities. Has anyone else used the program with success? Apparently it can take days to finish running sometimes, but I guess it works surprisingly well.
This is it, for anyone who doesn't know about it:https://www.grc.com/sr/spinrite.htm
