The RAID is a SCSI connected direct attached storage 16 bay unit made by Maxtronic. It is a Janus 6640, is case that helps anything. At the time of its problem, it was mounted read-only as I was trying to be careful of the data, since the main volume failed and this was our only copy. So maybe the cache isn't a big deal. I'll try the "dead" drives tomorrow with a WD utility. I'll give Spinrite a try, if the WD utility doesn't revive them. thanks a lot for the help. I'll let you all know how things go.
