Obtain the latest version of ADU.
Unrecoverabl
e read error
Read parity errors were detected
when attempting to read same data
from both sides of mirrored
memory. Data loss will occur.

WARNING -
Drive Write
Cache is
enabled on X
Drive has its internal write cache
enabled. The drive may be a
third-party drive, or the operating
parameters of the drive may have
been altered. This condition may
cause data corruption if power to
the drive is interrupted.
Replace the drive with a drive supplied by
Compaq, or restore the operating
parameters of the drive.
Warning bit
detected
A monitor and performance
threshold violation may have
occurred. Status of a logical drive
may not be OK.
Check the other error messages on the
diagnosis screen for an indication of the
problem.
Write memory
error
Data could not be written to cache
memory. This typically means that
parity error was detected while
writing data to cache. This could be
caused by incomplete connection
between cache and controller. This
is not a data loss circumstance.
With power to system turned off, verify
that the cache board is fully connected to
controller.
Wrong
Accelerator
This could mean that either the
board was replaced in the wrong
slot or placed in a system that was
previously configured with another
board type. Included with this
message is a message indicating
the type of adapter sensed by ADU
and a message indicating the type
of adapter last configured in
nonvolatile RAM.
Check the diagnosis screen for other error
messages. Run the System Configuration
Utility to update the system configuration.
