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.
