Had an IBM 60 gig with SERIOUS media damage in the critical area of the drive (boot sectors, directory structures, etc). Norton wouldn't even see the disk. DiskWarrior (an outstanding product regardless) could not rebuild the directory. Total Recall's Virtual Lab could see the drive, but would NOT scan it on any setting. I was about to give up. I downloaded the demo and the scan showed me all my files with folder structure intact. I recoved one file to test it. Worked perfectly. Then I purchased it to unlock the recovery of all my other files. Got back about 10 Gigs worth of data ( it missed about 15 files out of 4325 because of the media damage). You've got nothing to lose by d/l the demo if you have major drive trouble and need to recover. And at $89 it's thousands less than sending your drive off to some expensive recovery company.
