Ah, William, I think you may be right, despite the fact that XP Help tells you how to do it, and even adds: "Important When mirroring the system volume, always test to make sure you can start Windows XP Professional from each mirror in the event that one of the disks fails. Always use identical disks and controllers to help avoid startup problems." Curious. Looks like I originally fell for the confusion I referred to in my other posting. Maybe I did well to choose the hardware option? ;-) John > -----Original Message----- > From: dba-tech-bounces at databaseadvisors.com > [mailto:dba-tech-bounces at databaseadvisors.com] On Behalf Of > William Hindman > Sent: 15 May 2004 16:50 > To: Discussion of Hardware and Software issues > Subject: Re: [dba-Tech] RE: Going to Raid - Win2K > > > ...the only way of mirroring a drive under WXP on a WXP > system, that I'm aware of, is using a hardware RAID board > that does the mirroring beneath the WXP layer ...I'd love to > be proved wrong on that. > > William Hindman > "The world's becoming a museum of socialist failures."
