Critical Array Status Error Reported during Boot
If a critical status error message appears on the ATA 133 Raid BIOS startup screen for a mirrored array (see below), there is a drive in the array that has failed or is not responding. ATA 133 RAID will identify the failed drive by channel number and Master/Slave designation (if 2 drives exist on the same cable). The mirrored array has lost its fault tolerance, but will still perform normal drive reads and writes.
Try powering the system off and on to reset the drive. Also confirm that cables are properly attached and the drive is receiving power. If the drive still appears to have failed, you need to follow the procedures to rebuild the array to restore redundancy.

Drive cannot be formed into an array
Drives must support Ultra DMA or Multi-word DMA and be free of media defects to be added into an array. We recommend using new identical drives for each array. Secure data and power cabling while checking for proper alignment. Typically, Pin 1 of the drive is closest to the power connector.

Possible Master/Slave problems
Master/slave problems may exist between two ATA or IDE drives of different brands attached to a single cable. For both compatibility and better performance, choose drives of the same model/brand and install them on separate cables.

System CMOS displays C: or D: drive failure during Startup
Do not reference C: or D: in the Mainboard Standard CMOS for drives attached to the ATA133 Raid controller. Only enter drive information in the Mainboard CMOS for drives attached to a conventional add-on or onboard IDE controller.

FDISK reports a much lower drive capacity if a single physical drive or a striped array exceeds 64GB
Due to a limitation with FDISK, the utility reports only the storage capacity that exceeds 64GB. This is a cosmetic, not actual, limitation. Simply create a single DOS drive partition, reboot, and then format the partition. The Format command will recognize the total capacity of the partition accurately. Windows NT/2000/98 will now recognize the total capacity of your array.
