Hi I've got two identical WD SATA2 250gb drives that I want to connect in a RAID 1 array. My motherboard is a DFI NF4 Ultra-U. My XP is currently installed on one of these drives (on an 18gb partition). Can I make a ghost of the XP partition and restore it as if nothing had happened after the process? If not, do I need to do something different when reinstalling XP, or will it treat the two drives as one disk? (Can it be that I _must_ use drivers, from _a floppy disk_??) What are the steps, one by one? 1. After making a ghost, I remove all data from the two disks. 2. I enable RAID (1? just "raid"?) in the BIOS setup. (Where do I configure which disks are to be in the array?) 3. I reinstall windows / restore the ghost? (After creating an 18gb partition? Without creating one? Can I create a different one? I guess that's more of a Ghost/Acronis question...) If the reality is that the disks don't just act as one drive after a simple BIOS change, who will know it's one drive? An XP? An XP with RAID drivers (NVIDIA? DFI?)? How about a program that I run from Hiren's Boot CD? As you can see, a lot of questions need to be answered, and I hope will be, before I attempt this... Thanks in advance, j PS - How easy will it be to recover data in case one of these disks crashes?
