Well, it could be that you've got a bad sector on the FreeBSD portion of the drive, which is causing the drive to reset and reread the bad sector. Depending on the drive mechanics, this could make a ticking sound as the heads park themselves (well, maybe not park in the 80s hard drive sense, but at least move off of the writeable surface) while the drive resets, and then seek back to the bad location. I don't know if FreeBSD has any native tools to check for such errors and mark them (a la DOS's scandisk), and since I'm guessing that these drives are ATA, you can't use the controllers' "scan media for defects" option like you can for SCSI drives. -- Matt Emmerton To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
