I recently needed to upgrade a machine that had a mirrored pair of 150Gb Serial ATA (SATA) drives. This was a small form factor (SFF) machine, a Shuttle SB51G XPC, with the drives mirrored via the on-board SATA RAID controller that’s part of the Intel 865G chipset.
What I wanted to do was remove the mirror, leave one of the drives (with its content intact) as the boot drive, and add a 300Gb SATA drive as a (non-mirrored) second drive. In the end, this turned out to be fairly simple to do, but it took me a while to figure it all out.
