Bad Block Scan
On the Disk Information screen, select a disk then click on "Detect Bad Block" to perform bad block
scan of the associated disk. The result is only for reference and the system will not take any action
from its results.
The bad block scan can be terminated by clicking on "Stop Detect Bad Block".

Description
Tray the hard disk is installed in.
Model name of the installed hard disk.
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.
The current temperature of the hard disk in degrees Celsius.
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 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.
Set short or long time to test.
Result of the test.
