TLER Setting
TLER (time-limited error recovery) functions provide support for WD Caviar RE (RAID)
series disks. This is a new option from WD to support RAID features that were
traditionally missing from standard desktop drives. TLER is a method of signaling the
system RAID controller in the event that an error recovery process is taking longer
than time-out specifications allow. This prevents the RAID controller from dropping
the drive from the array during this period. Default value is manufacture setting. You
can select between 5, 6 and 7 second. This feature is to setup the HDD internal
timeout value.
Timeout Setting
Disk time-out is a registry setting that defines the time that RAID controller will wait
for a hard disk to respond to a command. You can modify the retry value by entering
a new value in the edit box beside this button and then selecting the button.
Normally you should not need to modify this value. Default value is 12 seconds: You
can select between 0.8~120 second.
Number of Retries
This setting determines the number of access that will be attempted before the
current command from the RAID controller to the disk drive is aborted. You can
modify the retry value by entering a new value in the edit box beside this button and
then selecting the button. Normally you should not need to modify this value. There
are two selections, either 2 retry or 3 retry.
