4.1.2 Write Cache Mode
This bit sets the write cache mode. If set to "ENABLE" (Default Setting meaning Write Cache Enabled),
the
SATA Mirror Drive
will signal completion of command processing to the host computer when the
data has been written to cache memory. If set to “ON”, the
SATA Mirror Drive
will signal completion of
command processing to the host computer when data is actually written to the drive unit.
Always observe the shutdown procedure specified for the host
computer’s operating system. In delicate situations, try to wait at
least 10 seconds to be sure that both the access indicator and the
drive status indicator have stopped flashing before shutting off the
power. Turning off the power while the access indicator or the drive
status indicator remains lit may result in loss of data currently located
in cache memory.
Important
4.1.3 Revival Reconstruction
If the bit is set to "ENABLE" (Default Setting meaning Revival Reconstruction Enabled), the
SATA
Mirror Drive
will attempt to do data reconstruction after Error Recovery Procedure fails while in Retry
Mode. The
SATA Mirror Drive
will not remain in Degraded Mode but instead, will automatically do data
reconstruction to trying to revive the drive up to two times.
4.1.4 Buzzer
If the bit is set to "ENABLE" (Default Setting meaning Buzzer Enabled), the buzzer will sound when any
error is detected. In the event of a drive unit failure, the buzzer will continue to sound until the failed drive
unit is replaced. The buzzer can be stopped if the switch position is changed to “ON”.
Set back the buzzer to "OFF" after the failed drive unit has been replaced.
When an external bracket is used for the 5" Drive Bay installation, please make sure that S2-3 setting of
the Dip Switch is set to “ENABLE”. The buzzer sound can be turned ON and OFF through the Buzzer
switch in the external bracket. If the buzzer is turned OFF prior to drive replacement, slide it back to ON
after the new drive unit has been inserted.
