S.M.A.R.T. attribute definitions

Current Pending Sector Count - Attribute information

Attribute Name:

Current Pending Sector Count

Attribute ID:

197

Description:

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.

Critical:

Yes

Hard drives that support this attribute:

Samsung, Seagate, IBM (Hitachi), Fujitsu, Maxtor, WD (Western Digital)

What is the S.M.A.R.T. attribute?
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 (e.g.: the "Temperature" attribute indicates the temperature of the hard disk, the "Power-On Hours" attribute indicates the count of hours in a power-on state, etc.) Various manufacturers may use different sets of attributes.

Want to protect your hard drive from a sudden breakdown?

Modern hard disks support a self-monitoring technology called S.M.A.R.T (Self-Monitoring, Analysis and Reporting Technology). This technology allows you to monitor the important parts of hard drives, warning you if their condition is getting worse and data loss is possible. However, in order to use this information, you will need special software which can collect and process it. Active SMART is intended for just this purpose.
Install Active SMART to protect your HDDs and the data stored on them.
