I'll check these apps out. So far the only life I've found is with e2fsck -b 32768 /dev/sda1. This starts finding some things that make sense name-wise but then starts complaining about other things. Again, it's just mythtv video files so those can probably just be rerecorded at some point. The backups were for my Windows machines which are working right now so as long as I make some new backups elsewhere I should be reasonably safe unless I find one day that something I need then isn't on my machine right now. Sad when your backup strategy goes against you... Again, thanks for the pointers. - Mark
