While I have no direct experience using RAIDS on a Mac, we use them extensively with our servers (win2k and linux), but they're scsi, not ATA. What I'd do is unplug the striped channel and format the drives, make the new raid , then reconnect the first channel after flipping the switch back to striping. General rules: 1) Hardware is always better than software...and if you're using RAID0, you're after performance. 2) There is no way around backing everything up and restoring when reconfiguring a raid. (replacing disks, yes, you can do that *live*, but you cannot add a disk in most instances, especially when striping.) Then again, we use higer levels of RAID (RAID 5) The only time to choose raid 0 imo is when you absolutely *have* to have the maximum performance, and you do your backups religiously! -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
