Item Description
Tray Number
Tray Number
Tray the hard disk is installed in.
Model
Model name of the installed hard disk.
Power ON Hours
Count of hours in power-on state. The raw value of this attribute
shows total count of hours (or minutes, or seconds, depending
on manufacturer) in power-on state.
on manufacturer) in power-on state.
Temperature Celsius
The current temperature of the hard disk in degrees Celsius
Reallocated Sector
Count
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).
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
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 Pending
Sector
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
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
sector as remapped. If this attribute value remains at zero, it
indicates that the quality of the corresponding surface area is
low.
Raw Read Error Rate
This attribute value depends on read errors and disk surface
condition, and indicates the rate of hardware read errors that
occurred when reading data from a disk surface. Lower values
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.
Seek Error Rate
Rate of seek errors by the magnetic heads. If there is a failure
in the mechanical positioning system, servo damage or a
thermal widening of the hard disk, seek errors arise. More seek
errors indicates a worsening condition of a disk surface and the
errors indicates a worsening condition of a disk surface and the
disk mechanical subsystem.

NOTE
If the Reallocated Sector Count or Current Pending Sector of a hard
disk drive is not zero, the status of the disk will show “Warning”. This
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 disks as soon as
bad sectors on the disk, and they should replace those disks as soon as
possible.
RAID Information
From the Storage menu, choose the RAID
item and the RAID List screen appears.
This screen lists the RAID volumes currently
residing on the N5200. From this screen, you
