Use smartctl if the drive supports it.  If it doesn't, a brute force
nondestructive approach is to 'cat /dev/xxx >/dev/null' to force every
sector to be read and watch for error messages on the screen or logged
to /var/log/messages.  Or you could use the 'badblocks' program.

I usually low-level SCSI drives when moving them to a different
controller.  It's probably just superstition now but it used to
make a difference.  Or course you can't do that with IDE drives.
