Heck, and all these years Nick Holland has been telling us that real men don't back up. :-) Off list it was suggested to me to do a "Consistency Check" through the RAID controller BIOS Utility (ctrl-m), and sure enough, after 22 hours, it reported a status of "FIXED" so it obviously found a problem or two. I know I had one bad powerdown due to some idiot kicking the powercord out of the box (ummm... I'll admit to nothing), so the bad consistency state may have been the issue. I'll look into it further, but for the moment I think I fixed the problem (thanks Marco). kind regards, jcr
