You replace the hard disk. Bad sectors are "physical" defects. There is no
fixing them.

Replace the hard drive.
Bad sectors indicate imminent hard drive failure.
Back-up important data IMMEDIATELY before the drive fails.
 
Hi:

You can not remove a bad sector in hard disk. In same cases you reformat it
and mark as a bad sector, or use a 3rd party software to do so. SCSI hard
disks have technology that "mask" the faulty sector, with any user
intervention.
 
with a modern HD, if window's CHKDSK command reports bad sectors/clusters
then you have a problem - modern drives handle bad sectors internally, and
ONLY report them to windows if they run out of spare sectors (of which
there are typically hundreds) - an indication the drive is failing. backup
and replace the drive ASAP.

If the drive is SMART compatable (IDE, but not newer SATAs), the maker
probably has a SMART util that can tell you the drive's status, and if it
has run out of spares.
