Writing to the bad sector will remap it (on modern hard drives, last
5 or 8 years).  Just use dd to write to the affected area or the
whole drive.  After that, the block will no longer be "bad".

Doing a low-level format of the drive will generally cause the drive
to skip over all bad sectors and build a new "spare sectors" area.

Modern drives can be configured to continuously test themselves via
SMART, with the --offlineauto option to smartctl.  SMART can also
tell you if the drive appears healthy.

Thanks Tony, that cleared a lot about smarttools also a lot. I always
used to wonder about how smarttools can be used to fix a hdd bad
sector. Now I learned from your mail that just writing to the bad area
of the disk will fix it because disks are intelligent enough these
days. smarttools is used for just diagnosis purposes.
Also I am goinng to put
smartctl --smart=on --offlineauto=on --saveauto=on /dev/hda in my /etc/rc.local.

Thanks again.
Vijay
