Are you sure the problems >are with the controller and not with the drive? At on time, both Seagate and Quantum had "stiction" problems. This was caused by a supplier of lubricants for the hard disk industry. They shipped batches of solvent that was too viscous. The result was, that when you powered down your hard disk, the heads would move to the landing zone and get stuck. When you tried to spin up the drive, it would not be able to retract the heads to track 0. Quantum solved the problem by changing their rom code to increase the power curve on the head controller servo. At power up it would simply yank the heads back harder than usual. I don't know what Seagate used as a fix. Rick Kelly rmk@rmkhome.UUCP frog!rmkhome!rmk rmk@frog.UUCP
