Sure, if you're present. I regularly ship systems overseas where the power fails frequently. The inability to boot because one disk got hosed is Bad News (tm). It depends on your exact situation, I was just pointing out that SW RAID doesn't cover all the bases HW RAID does. Murphy dictates that the moment one of your disks down your system will glitch/panic/etc and reboot and then you'll be stuffed :) -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C
