The problem: PC with single boot HD and 2 disk RAID 1 array (data) is stable for over a year, then suddenly develops boot problem. Weird part is, it boots just fine if I unplug the drives in RAID array, and continues to work fine if I plug them in while Windows is running. The array rebuilds itself, but is otherwise normal (data accessible, etc.).
If I reboot with all drives plugged in the boot process hangs after POST, with the error message "boot drive not found". If I try to boot from the Windows disk to repair, I get a BSOD once the loading process is finished. If I turn the PC off, unplug the RAID 1 array and reboot, the system boots right into windows.
I don't know why this problem suddenly appeared (no new installs, etc.), or how to fix it. Any ideas?
