S.M.A.R.T. Information

Item

Description

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.

Temperature Celsius

The current temperature of the hard disk in degrees Celsius

Reallocated Sector

Count of reallocated sectors. When the hard drive finds a

Count

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 Pending

Current count of unstable sectors (waiting for remapping). The

Sector

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

 

low.

Back

Press Back to go back to the Disks Information screen.

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 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 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 N8800. From this screen, you can get information about the status of your RAID volumes, as well as the capacities allocated for data and iSCSI. There is also a graph which represents how the RAID volume is currently allocated.
