Since you say "upon system powerup", I would guess that the drive isn't spinning up and "going ready" before your controller queries it. Have you tryed a VNP (Vulcan Nerve Pinch, warm reboot, CTRL-Amiga-Amiga) when this occurs? If it fails a cold start, try the warm boot. If it comes up, the problem is that the drive isn't coming ready before the controller queries it. It's intermittent, because the drive is mechanical in nature and all manner of things can affect the spin up time (temperature of the drive, humidity, lotsa stuff). It's most likely the Xetec controller firmware. It's asking the Quantum to boot before it has spun up, hence the drive reports "not ready" and the autoboot fails. It's not really Quantum's fault, since all they can do is guarantee a maximum spin up time. It appears that many SCSI adaptors don't allow enough time for slow drives to come up. I have a similar problem with my HardFrame, Seagate ST-138N and Conner CP3200. The system boots off the Seagate. On a cold start, the Seagate doesn't always spin up and go ready in time (sometimes it sticks and doesn't spin up at all, but that's a different story 8-). The Conner, on the other hand, won't automount on a WARM boot, but will automount on a cold start (if the Seagate comes up in time). My solution: I don't shut the system down unless I do maintenence on it. It's running 24 hours a day for months on end. I do turn off the monitor, however. Like I said, try a warm boot when the problem appears. And contact your SCSI adaptor vendor (Xetec) about increasing the allowable spin up time. -- ---------------------------------------------------------------------------- [- O] Rick Stevens ?
