As the message line reads... I recently upgraded my Hard Disk controller to the A2091 from the Pacific Peripherals Overdrive card (32K diskperfs - BLEAH!), and am now experiencing some very strange behavior. I have 3 drives on my system. SCSI Device 0: Seagate ST251-N (40 Meg) SCSI Device 1: Quantum 80S SCSI Device 4: CDC Wren IV (300 Meg) In each case I set up the drives by reading the drive definitions off the drive to be formatted. The only "partitioned" drive is the CDC, which has a 100 MB partition and a 185 MB partition, in that order. Intermittently, I will get a situation where a drive freezes on and locks up the system. This usually occurs during the rather robust operation of unbatching news from AmigaUUCP, but has occurred at other, less robust times. Those other times usually are during file transfers on the same device. The device in question seems to be the CDC. Also just this morning, it took 9 reboots (3 of them cold reboots) to get to workbench. The Quantum is my sys: disk. The Seagate holds all my UUCP configs and executables. The CDC is my archive disk that only has assign references. During my reboot attempts, each time the startup sequence referenced a drive, that drive at random (as far as I can tell) was the one that locked up the startup sequence by freezing in read mode. My boot sequence is very strange when watching the drive lights. The sequence of drive accesses when no floppies are in the system goes like this: Device 0, Device 0, Device 4, Device 0, Device 0, Device 4, Device 1, execute Quantum s:startup-sequence, Workbench drive accesses. I must mention that I have *never* had a system freeze up caused by the Pacific Peripherals Overdrive. My system: A2000 4.3 rev. Fat Agnus (1M Chip) 2 Floppies Micron 2 Meg card. A2091 Seagate 251-N in 5" drive bay. Quantum 80S installed on A2091 CDC Wren IV external connected through back DB connector. Supra Modem 2400 Standard Keyboard Standard Mouse. I am desperate. Any and all help accepted! -- Stephen N. Opal sno@ais.org rjf001!sno-1!sno
