UncorrectableSectorCount
UncorrectableSectorCount is a term used in the context of hard disk drives (HDDs) and solid-state drives (SSDs) to describe the number of sectors on a storage device that have become unreadable or uncorrectable due to data corruption or physical damage. These sectors are typically identified and marked by the device's firmware, which attempts to read and correct data errors using error-correcting codes (ECC). When the firmware is unable to correct these errors, the sectors are considered uncorrectable.
The UncorrectableSectorCount is an important metric for assessing the health and reliability of a storage device.
In the case of HDDs, uncorrectable sectors can be caused by various factors, including physical damage to
To mitigate the risk of data loss, it is recommended to regularly back up important data and
