I beleave that the Sun formats the SCSI drive to 1024 byte sectors, while DOS will want 512 byte sectors. The Exabyte shouldn't be a problem though. >I've heard that you should buy the SCSI controller from the same >people you buy the disk from, so I looked in the R-Squared catalog and This can be helpfull if they verify that the whole system plays together. This means they have tried the drive and controller in the package you are selling. On the other hand, if you are running standard applications, a good source is to ask the drive manufacturer which adapter they recommend. Then check with the adapter manufacturer and make sure they support what you are doing. >sure enough, they sell a SCSI controller to attach their drive to an >AT for $1600!

Seems a bit steep; our adapter lists for $249, others are higher (up to $350 I think) down to about $50. These are MFSRP; street prices are generally lower. The difference in price is: performance, included drivers, functionality, and marketing. Might be that these guys are selling with a software package or some specialized system into a niche market; other than that, I don't know what could justify that kind of pricing. > >Thanks for any help you can offer. > >Tim Sullivan (tims@goshawk.lanl.gov) Hope I helped. --rick -- =============================================================================== Rick Wagner / Always Technology email: rick@always.COM 31336 Via Colinas, Suite 101 Voice: 1-818-597-1400 Westlake Village, CA 91362 Fax: 1-818-597-1496
