This is the correct way, since the drive could be hiding bad blocks by
reallocating dying sectors.
Look at your pending sector count, this should be 0 on a good disk. If
it does have a value, it should go away when the sector is
moved/reallocated.

Personally, I don't expect much advanced disk diagnosis out of a system
installer (be it Linux, Windows or Freebsd).
Use this (it's freedos): http://hddguru.com/software/2005.10.02-MHDD/
It can deallocate bad sectors (will require reformat) and show "slow"
sectors as well, in a waterfall-type display.

As far as in the base system, it may be a little late for this, but ZFS
would indicate unreadable blocks via checksum errors after a scrub,
would it not?
