I have 2 identical Maxtor 60 Gigs. I tried to mirror them but never got the "mirror" clickable when I right click on the Drives in Disk Managment. It's always grayed out. Both Disks are already set to Dynamic disk, Drive 1 has all space "unallocated". Followed all the instructions in XP's help but still get a "grayed out" MIRROR option when I right click. I treid to do this in the same machine with Windows 2000 Server and everything went flawless....... I got MIRROR RAID 1 on my system with 2 Hard Drives. Just cant seem to do this in Windows XP Pro.
