Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Used ABBR on SCSI disks all the time, very nice. Remember reading on hackers somewhere that newer drives like IBM supported this feature. I'm getting a few bad blocks on a 75GB IBM drive (at least according to the ata driver), and rather than replacing it and moves on, the disk basically dies. However, I run the IBM drive fitness test, it works some magic in there writing data to the drive, and the drive is back, and the failed block now seems fine. So is there some equivalent of camcontrol or scsicmd for ATA drives that turns on this feature, and allows my running system to take advantage of it? Or do I just write nul's to the block or 0's, and it's supposed to do it automatically? or do I just punt.
