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.
If the Reallocated Sector Count > 32 or Current Pending Sector of a hard disk
drive > 0 , the status of the disk will show “Warning”. This warning is only used
to alert the system administrator that there are bad sectors on the disk, and
they should replace those disks as soon as possible.
NOTE
