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, proceed to "Rebuild Array" option of FastCheck detailed on page 35.
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. Promise recommends using new identical drives for each array.
Re-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. Refer to the Drive Setup
by Connector chart for more recommended drive placements.
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
RAID Function 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, 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.
Unable to partition or format array
The Reserve Sector of one of the drives has become corrupt or bad. Removing the
Reserve Sector will remedy any issue related directly to a Bad Reserve Sector.
WARNING: Before removing the Reserve Sector of the drive(s), backup
any existing data. Removal of the reserve sector of any drive perma
nently deletes all existing data on the hard drive. For Mirrored arrays
(RAID 1), you should remove the Reserve Sector from the "mirrored" drive first (this
will appear during Step 3 below) then rebuild the mirrored array. Remove the Sector on
the Master Drive only as a last resort. For Striped arrays (RAID 0), removing the
Reserve Sector from any of the drives that are striped will destroy the arrayed data.
