The S.M.A.R.T. attributes are specific properties (parameters) of various parts of a disk.
|
||||
S.M.A.R.T. uses attributes to monitor the disk condition and to analyze its reliability.
|
||||
|
||||
Script check HDD from S.M.A.R.T with the following properties (if your HDD supports it):
|
||||
|
||||
** Spin Retry Count (src) **
|
||||
Count of retry of spin start attempts. This attribute stores a total count of the spin start attempts to reach the fully operational speed (under the
|
||||
condition that the first attempt was unsuccessful). A decrease of this attribute value is a sign of problems in the hard disk mechanical subsystem.
|
||||
|
||||
** Reallocated Sector Count (rsc) **
|
||||
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.
|
||||
|
||||
** Reallocated Event Count (rec) **
|
||||
Count of remap operations (transferring data from a bad sector to a special reserved disk area - spare area). The raw value of this attribute shows the
|
||||
total number of attempts to transfer data from reallocated sectors to a spare area. Unsuccessful attempts are counted as well as successful.
|
||||
|
||||
** Current Pending Sector (cps) **
|
||||
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 some sector, 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.
|
||||
|
||||
** Offline Uncorrectable (ou) **
|
||||
Quantity of uncorrectable errors. The raw value of this attribute indicates the total number of uncorrectable errors when reading/writing a sector.
|
||||
A rise in the value of this attribute indicates that there are evident defects of the disk surface and/or there are problems in the hard disk drive
|
||||
mechanical subsystem.
|
||||
|
||||
** Total health test (pass) **
|
||||
This is test provided by Smartmontools. If total disk state is "health", Smartmontools marked as "PASSED".
