that is working quite well with two drives that are combined to look like a single drive, not a Raid 1 environment. I want to replace the existing 2 - 20 Gb drives that work just fine, with 2 - 160 Gb (ATA-100) drives so that I can have more space. Ultimately, I want to configure them as Raid 1 but that can come after the changing of the drives. So I have heard two possible methods, (1), backup any existing data I have, change the existing environment to a Raid 1, then take out one of the drives and replace it with one of the new 160 Gb's. The unit would then copy the OS to the new 160 Gb drive, and when finished, move it to primary, and fail the second one again replacing it with a 160 Gb drive. The (2) method appears to remove the second drive without changing to Raid 1 first, replace it with a new 160 Gb drive, then have it come up after the OS is copied, move this new drive to primary (either Primary or CS) and then remove the second drive which was a 20 GB drive. I am also not clear on what wiki is (I HAVE read all 500 plus pages, but dont remember that term) and would appreciate any help.

It is always better to do a backup, whe you start playing with disks. After you have backed everything up: MARK YOU ORIGINAL HD's AS M/S OR FT/BK. Keep the master as a OS keeper if you like.
Check you drive configuration. Singe disk can be Any raid set, the only indication would be usable space. If you are showing over 20 gig usable you are proably raid 0, Which means there is nothing you can do but to backit up before upgrading. The process I would use would be to break the set to JBOD. reboot the server. Then change the drives to raid 1, reboot and let it build the set. approx 2 hrs.
On a 2000 the drives should be in a master/slave config. By looking at the HW & BIOS you have a version 2. The master is the FT disk, end of cable. So fail the slave, Back drive. Install your new disk and reboot. The snap should format and install the OS on it. Check you drives status from the disk secton. Once the Disk ligh has gone out. You will be ready to fail the master. and do the same process again. Your OS will support hd >137gig. If you end up with a broken mirror, simply change back to JBOD, then back to RAID1.
