You may also perform a disk SMART test; simply click “Test” to start the SMART test. The result is only
for reference and the system will not take any action from its results.
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 min-
utes, 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 sec-
tor 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, 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.
Test Type Set short or long time to test.
Test Result Result of the test.
Test Time Total time of the test.
