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.
Time Out 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 8 seconds: You can select between 3~8 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, 2 retry or 3 retry.
