I wasn't sure if Win XP could do CHDSK on a RAID 1 Array. I haven't done it yet. I ran a defrag utility on it and thought about issues with info being defraged to bad sectors. I was uncertain if the array would be corrupted if windows did error checking and repair on the array. Do I need to undo array and run CHDSK on one SATA drive and then rebuild array afterward?
