Disk Mirroring with XP and SCSI drives

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?

XP is ok in "mirroring" drives,they even incude it in the software:XCOPY
However,this works only with IDE drives with the two on same IDE cable.
Besides,what you want to do is really a RAID configuration RAID 1 to be
specific,why not get a SCSI RAID controller.....What specifically is greyed
out,
diskmgmt.msc Doesnt mirror the IDE drives anyway,that done in cmd,you might/
could open cmd type:XCOPY /?
 
Adaptec does not have a Ultra 320 PCI card w/hardware RAID. PCI-X, yes.
And that's the reason for his question I suppose. But should have provided
more specifics.
