I don't believe that "HDD Regenerator" does anything more than the mfg's diag program or SpinRite 6 would do. All it seems to do is trigger the drive's own internal sector-remap feature. If it's re-allocated 80K sectors - you're in trouble. With that many bad, you may have a bad/defective head actuator assembly. (Translation = drive is toast, buy a new one and/or RMA that one.)
If you want to save your data, whatever can be saved, I recommend using Ghost 2003 to do a "raw" image backup (sector-by-sector, not the default file-by-file), onto files on another HD, or directly to another HD of similar or larger size. (Use the "-fro" parameter, IIRC.) This will skip over sectors that cannot be read, and salvage as much readable data as possible. If those bad sectors are part of the partition table/FAT/etc., you will have futher problems, in which case you should run some serious data-recovery software on that backup image drive, in order to save your data. Best of luck.
PS. HDD Regenerator cannot actually repair any sectors at all, IDE HDs don't work that way. All they do is swap the "bad" sectors with a hidden "good" replacement sector, so that the computer doesn't see it as "bad" any more, but there is a limit on how many hidden "good" sectors that any one drive keeps secretly stashed away.
