Ric, Both ATA (ATA8-ACS) and SCSI (SBC-3) have recently added command support to flag a block as "uncorrectable". There is no need to send bad "long" data to it and suppress the disk's automatic re-allocation logic.
That'll be useful in a couple of years, once drives that have it become more common. For now, though, we're hacking current drives using READ/WRITE LONG commands, with a corresponding patch to libata to allow for the longer "sector size" involved. Having real bad sectors, exactly where we want them on the media, sure does make testing / fixing the EH mechanisms a lot more feasible.
