One of my hard disk is showing symptoms of impending failure. Before
sending it for replacement, I would like to blank out the entire disk
(80GB in my case).

Is the following sufficient?
dd if=/dev/zero of=/dev/sdb1 bs=1K count=78148161  (sdb1 is the entire
disk - MBR)



dd is fine.

Yo can use "shred" also.
