I have a HP system with 2 SCSI drives (38Gig) (identical).
Up until now I have used the first for system and apps and the second for
data.
I have just add a largish IDE drive for data so I want to mirror the system
drive with the 2nd SCSI drive.

From readings, XP can't handle disk mirroring (ie SW mirror).
Q1. Why then is it even a greyed out option in disk manager?..Confusing.
Q2. Why did MS not make it available in XP professional? Is it available in
Vista?

I guess that hw mirroring is what is required.
My current controller is Adaptec AIC-7902-Ultra320 SCSI.
I assume that I can't do hw mirroring with it..??
Q4. Can I get a SCSI controller that supports disk mirroring?
