Your approach is illogical and irrational. You know it, but refuse to admit it. The approach I use, which is, uh, rational, is two IDE hard drives and decent mirroring software. Heck of a lot cheaper than any SCSI Raid solution. SCSI is not measureably more reliable than today's IDE drives. Tom "David H.
