For this reason, HDD SMART Status Polling was added to enable
scanning of the HDD temperature function in the version 1.36
date: 2005-05-19 (and later). It is necessary to enable “HDD
SMART Status Polling” function before SMART information is
accessible. This function is disabled by default.
The following screen shot shows how to change the BIOS setting
to enable the Polling function.
• Disk Capacity Truncation Mode:
ARECA RAID controllers use drive truncation so that drives from
differing vendors are more likely to be able to be used as spares
for each other. Drive truncation slightly decreases the usable
capacity of a drive that is used in redundant units.
The controller provides three truncation modes in the system
configuration: Multiples Of 10G , Multiples Of 1G , and No
Truncation .
Multiples Of 10G: If you have 120 GB drives from different
vendors; chances are that the capacity varies slightly. For exam-
ple, one drive might be 123.5 GB, and the other 120 GB. Areca
drive Truncation mode Multiples Of 10G uses the same capac-
ity for both of these drives so that one could replace the other.
Multiples Of 1G: If you have 123 GB drives from different ven-
dors; chances are that the capacity varies slightly. For example,
one drive might be 123.5 GB, and the other 123.4 GB. Areca
drive Truncation mode Multiples Of 1G uses the same capacity
for both of these drives so that one could replace the other.
No Truncation: It does not truncate the capacity.
