My computer has two Western Digital Caviar Black WD5001AALS 500GB hard drives configured in Raid 0. As the ASUS P6T Deluxe V2 motherboard begins to POST both hard drives are shown on the POST screen but one of the two hard drives is in red letters with the message "Error Occurred (0)". Windows 7 has on one occasion had trouble booting but otherwise seems to boot normally. I knew just enough to configure the BIOS in Raid 0 and to install Windows 7. The above Error Message is seen with each boot since it started three days ago. I made a physical inspection of the hard drives and their power and SATA connections. All connections were secure. Can someone give advice and assistance in how run down a problem in Raid 0 without screwing up the Windows7 OS and its files.
