Troubleshooting & Tips
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 to use new drives of the
same model. Re-secure data and power cabling while checking for proper
alignment. Typically, Pin 1 of the drive is closest to the power connector.
Critical Status Error during boot
If a critical status error appears on the FastTrak66 BIOS startup screen for a
mirrored array, there is a drive in the array which has failed or is not respon-
ding. The mirrored array has lost its fault tolerance but will still operate
Before attempting a recovery, 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 detailed in Chapter 4.
System locks up during bootup or when Windows starts
There may be a possible IRQ conflict with an ISA card. Identify what IRQs are
used by ISA cards, enter the Mainboard PCI Setup, and reserve the IRQ for use
with ISA. PCI slots cannot share IRQs with ISA cards.
Intermittent data problems
Do not exceed the 33Mhz PCI Bus speed. Pentiums set to higher than default
settings or AMD K6 and Cyrix CPUs can exceed these limitations and cause
intermittent boot and data problems.
Different drive lettering under Windows NT
This may happen when using a SCSI card in addition to the Promise card.
Windows NT does not necessarily load the driver for the boot device control-
ler first. This results in a drive that in MS-DOS is the C: drive being the D:, or
E:, etc. in Windows NT. Use Windows NT's Disk Administrator utility to reas-
sign the letters which NT has assigned to the drives. See your Windows NT
documentation for instructions on how to use Disk Administrator.
