I have two SATA 120 GB disks, configured in RAID 0. which are seen in Windows XP as one disk (albeit a very large disk). Would PM work to partition the drive(s). I am concerned that it would not be able to see the split on the two drives and may create unusable partitions. I could go down the "install it and see" road, but I would rather have some feedback here first, possibly from someone who has RAID drives, and who has done it. Many thanks.
