Whatever brand of hard drive you have, download there hard drive utility software, this software asks you to make a bootable disk floppy.
Part of these utilities allow a full S.M.A.R.T test dianostics but better still are other utilities that can low level format and atempt to recover the drive back to factory settings, I have seen a high sucess rate in recovering hard drives after they have reported bad.
Once you have gone through the recovery process you can re-run the S.M.A.R.T test to see if it's status has changed.
