Netware 4.1) The first year or so of production of ST-410800N's (hmm: I don't think that number is quote right, ST418000N maybe? ST4108000N?) we had saw 100% failure rate. Eventually the replacements held up. Not sure it was the only change but I think the good drives have firmware 0025. The failure mode was the drive was dead if power was interupted in service. No bad blocks or anything like that, just nothing on the SCSI bus. We became terrified of turning them off. Once running they were fine. You know that is a monster 5-1/4" drive? Needs lots of cooling and power. IMHO you would be better off with either an ST19171W or IBM DCHS09. Street prices have plumetted to under $800. IBM DCAS 34330 drives are around $300 (only 4G) but are faster than many 7200 RPM drives and quieter than anything. Two of those would be better and cheaper than one 9G drive. Maybe not total less power than a 9G. With the IBM DCHS09 watch out because the same drive was sold in Ultra and Fast versions. Probably you would rather have Ultra. I think the DCAS drive was only sold in Ultra. A couple of ST19171W's arrived at work this week. $799 each from http://www.insight.com and each included an internal wide SCSI cable. Now we have about 25 of them. -- David Kelly N4HHE, dkelly@nospam.hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
