My tool of choice is the Hitachi Drive Fitness Test. It will test all PATA, SATA and SCSI drives, regardless of brand and/or S.M.A.R.T. support. It comes as a bootable floppy or bootable ISO image, using IBM PC-DOS.

It does have extra features when it recognizes the drive as an IBM or a Hitachi drive, though. It will offer to do repairs (using remapping) and it will write a log file that will enable you to automatically get an RMA on the Hitachi GST site.
