NOTE
The administrator can set the disk to power down after a period
of inactivity.
When the Status shows Warning, it usually means there are bad sectors
on the hard disk. It is shown only as a precaution and you should
consider changing the drives.

Count of reallocated sectors. When the hard drive finds a
read/write/verification error, it marks this sector as "reallocated"
and transfers data to a special reserved area (spare area).
This process is also known as remapping and "reallocated"
sectors are called remaps. This is why, on a modern hard disks,
you can not see "bad blocks" while testing the surface - all bad
blocks are hidden in reallocated sectors. However, the more
sectors that are reallocated, the more a decrease (up to 10% or
more) can be noticed in disk read/write speeds.
Current count of unstable sectors (waiting for remapping). The
raw value of this attribute indicates the total number of sectors
waiting for remapping. Later, when some of these sectors are
read successfully, the value is decreased. If errors still occur
when reading sectors, the hard drive will try to restore the data,
transfer it to the reserved disk area (spare area), and mark this
sector as remapped. If this attribute value remains at zero, it
indicates that the quality of the corresponding surface area is

occurred when reading data from a disk surface. Lower values
indicate that there is a problem with either the disk surface or
the read/write heads.

errors indicates a worsening condition of a disk surface and the
disk mechanical subsystem.
NOTE
If the Reallocated Sector Count or Current Pend ing Sector of a hard
disk drive is not zero, the status of the disk will show “Warning”. This
warning is only used to alert the system administrator that there are
bad sectors on the disk, and they should replace those disk s as soon as
possible.

RAID Information
From the Storage menu, choose the RAID item and the RAID List screen appears.
To configure your RAID settings, press the RAID Config button to go to the
RAID Configuration screen.
RAID Information
Item Description
RAID Level Shows the current RAID configuration.
Status Indicates status of the RAID. Can read either Healthy,
Degraded, or Damaged.
Disks Used Hard disks used to form the current RAID volume.
Total Capacity Total capacity of the current RAID.
Data Capacity Indicates the used capacity and total capacity used by user
data.
RAID Config Press this to configure RAID volumes.
RAID Configuration
On the RAID List screen, press the RAID Config button to go to the RAID
Configuration screen. In addition to RAID disk information and status, this
screen lets you make RAID configuration settings.
For more information on RAID, see Appendix C: RAID Basics.
27
RAID Level
You can set the storage volume as JBOD, RAID 0, RAID 1, RAID 5, RAID 6 or
RAID 10. RAID configuration is usually required only when you first set up the
device. A brief description of each RAID setting follows:
RAID Levels
Level Description
JBOD The storage volume is a single HDD with no RAID support. JBOD
requires a minimum of 1 disk.
RAID 0 Provides data striping but no redundancy. Improves
performance but not data safety. RAID 0 requires a minimum of
2 disks.
RAID 1 Offers disk mirroring. Provides twice the read rate of single
disks, but same write rate. RAID 1 requires a minimum of 2
disks.
RAID 5 Data striping and stripe error correction information provided.
RAID 5 requires a minimum of 3 disks. RAID 5 can sustain one
failed disk.
RAID 6 Two independent parity computations must be used in order to
provide protection against double disk failure. Two different
algorithms are employed to achieve this purpose. RAID 6
requires a minimum of 4 disks. RAID 6 can sustain two failed
disks.
RAID 10 RAID 10 has high reliability and high performance. RAID 10 is
implemented as a striped array whose segments are RAID 1
arrays. It has the fault tolerance of RAID 1 and the performance
of RAID 0. RAID 10 requires 4 disks. RAID 10 can sustain two
failed disks.
WARNING
If the administrator improperly removes a hard disk that should not be
removed when RAID status is Degraded, all data will be lost.
RAID Settings
Using Disk Settings, you can select stripe size, choose which disks are RAID disks or the Spare Disk, as well as enter a name for each disk.
28
Disk Settings
Item Description
RAID Check the boxes of the hard drives you wish to add to the
storage volume.
Spare Check a box to designate the replacement HDD for the storage
volume. This becomes the backup for any damaged hard drives.
Stripe Size This sets the stripe size to maximize performance of sequential
files in a storage volume. Keep the 64K setting unless you
require a special file storage layout in the storage volume. A
larger stripe size is better for large files.
Add Spare Press this button to add a new Spare disk.
Create RAID Press this button to configure a file system and create the RAID
storage volume.
Remove Click to remove the RAID volume. All user data will be removed.
