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 cannot 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,
