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 

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 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 

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.

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. 

 
To configure your RAID settings, press the RAID Config button to go to the 

RAID Configuration screen.
