You also may check that it is properly configured in all its parts. I > mean, clockings, cabling, cooling, etc ... ok... well, the hardware is a Tekram DC-390F. Attached hardware is: <FUJITSU M2949Q-512 0155> at scbus0 target 0 lun 0 (pass0,da0) <MICROP 4743 S150> at scbus0 target 1 lun 0 (pass1,da1) <MICROP 4743 S150> at scbus0 target 2 lun 0 (pass2,da4) <SAMSUNG WN32162U 0100> at scbus0 target 4 lun 0 (pass3,da2) All are narrow except the Fujitsu. All are internal, using no special addapters. Termination is turned on on both drives at the end of the chain. Motherboard is a FICA VA-503+ VIA based chipset that is *NOT* overclocked. As for cooling, nothing special, but the case is closed and has two exhaust fans and one intake fan. When I upgraded from the Advansys Ultra SCSI card, I didn't change internal cabling for the three narrow devices (and I'd been running that for 9+ months). The cable length on the narror part of the system might be a bit long, so I plan on next crash replacing it with a cable that only has three connectors for drives instead of the current five. Though the Tekram manual lists a length of 3 meters for 4 devices or less, which I know I'm less than, for the 1.5 meters (max of 8 devices) I'm probably pretty close to. Well, it also survived daily, but I did reduce the tags all above mentioned drives to 16, which may have made a difference. But only 16 tags is so few. :( Thanks for any help you can provide. -- John-Mark Gurney Voice: +1 408 975 9651 Cu Networking "Thank God I'm an atheist, that'd just be confusing." -- cmc To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
