I agree with that assement of the facts given here. But would like a few ``details'' filled in. a) When the lock up occurs are any drive select lights on solid? b) Do you have an LED hooked to the controller and what state is it when the lock occurs? c) Have you any process that core on occasion, or system panics of any form? [Looking for memory related problems which usually manifest themselves as random signall 11's if they occur in user land, and kernel panics if they occur in the kernel] d) And my most famous question I always ask, have your _triple_ checked that your scsi bus is properly terminated and built using high quality double shielded scsi-ii rated cables? [Applies to external cables, internal cables should be 110 Ohm 26AWG flat ribon cable.] Also make sure you are using ACTIVE termination, at fast scsi-II speeds anything less is dangerous. e) Back to the Barracuda and heat problems, what is the case temperature of the drives while operating (give them 4 hours to stabalize under your worse load before taking a measurement). Also make sure not to perturb the normal conditions for those 4 hours. -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation Company Reliable computers for FreeBSD
