</div>Spinrite is payware, but it does work for finding bad blocks on the<br>
underlying disk.<br>

The site is a bit dated, but the tool is good. Only downside I've found is<br>
that if you have a bad spot on your disk, the tool can spend a *very* long<br>
time trying to recover data from it even if you know for a fact there's no<br>
data there you want to recover (such as in the case of a disk you don't have<br>
any data on you care about). There's no way to tell it to just mark certain<br>
sectors bad and not try to recover data from them.<br>

I tried to use it to recover data from a SATA drive and it blew up with a divide by zero. Tech support for spinrite just told me that it works best on IDE drives. I ended up returning it for a full refund. When I want to recover a system now I use dd_rescue. <br>
