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