Total Capacity

Shows the total SATA hard disk capacity.

Disk Power

The administrator can set the disk to power down after a period

of inactivity.

NOTE

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.

S.M.A.R.T. Information

On the Disks Information screen, the status of each disk will be displayed in the Status column. Clicking on an OK or Warning link will display the S.M.A.R.T Information window for that particular disk.

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.

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

 

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

 

disk mechanical subsystem.
