|Before starting the install--when it's still at the dos prompt--type |
SCANDISK/SURFACE C: and enter. That will do a regular scandisk followed by a surface scan and should mark any bad spots so they won't be used.
Even if they're marked the drive may not be usable if the damaged area is in the boot sector.
But yeah, it's probably a good idea to find another drive. Bad spots are like cockroaches--more will show up.
