Basically impossible. Your best bet is to go to the hard drive manufacturers website and see if they have a software program (often a DOS program) that you can boot off a floppy and do this to the hard drive.
Or, if it's a SCSI disk you can often run a manufacturers program under DOS that talks to the SCSI card and will send the commands to the SCSI disk. Years ago with the old wd disk driver you could run bad144 and do this to ESDI and MFM drives. If you want to stress-test a hard disk then install and run one of the disk stressing programs in the ports collection.
