PC crashed. Troubleshooting indicated motherboard. Had OS running on two WD 10K RPM 74 GB HDs in RAID 0.
Replaced motheroard. When re-installing OS the BIOS and Windows would only recognize one of the WD HDs. It should up w/ now drive letter and not initialized. I swaped ports on MB and swapped cables from the HD that was working to the other but it still appears one is not working at all. I got PC up and running on another single HD.
Is there a way to check the one HD to see if it is really totally gone? I finally had to format the one good one to get it back usable.
Maybe this was not a motherboard issue after all.
