somehow drive 1 and 3 in the RAID 5 array were put offline by the controller. System will not boot into windows. CHKDSK says there are unrepairable errors and doesn't scan. NTLDR is corrupt is the msg I get when I try to boot to Windows. I left the office last night with drive 1 rebuilding because it was taking forever. Is it possible to do a repair install of windows that will have AD and exchange, dns still intact? what would be the best way to move forward?
