OK fair enough as I also am not sure myself.
As I understand it though if you ran SpinRight 6.0 and it -did- repair/recover a/few "bad" sectors then S.M.A.R.T. would update to reflect that..........things up and get a new drive befor it drops 100% dead.
you are mixing up two different things zol.
the first is what you are talking about and that is damaged sectors due to the power problem. that happens when the record of a sector gets corrupted. this can be fixed, the software you are refering to scans each and every sector and tries to regenrate those records. similarily if i zero fill (low level format) a disk, I get rid of the problematic secotrs as well, since during this format, all records of all files and these files are "deleted".
the second is a demaged sector on a hw level, whic is pretty much unrecoverable. this happens to a disk as time goes and it is why hard disks have an area to which they remap these sectors. the more sectors are remmaped, the more slower the disk operates since the reading head has to jump back and forth.
