Carefully follow the detailed steps in the post to fix the current pending sector count warning without much data loss.Ĭurrent Pending Sector Count is a critical S.M.A.R.T. The parameter indicates the number of unstable sectors on a hard drive or SSD that are yet to be remapped or reallocated. If you check the Current Pending Sector Count SMART parameter of your drive, you will notice a raw value of this attribute. The value indicates the number of sectors waiting to be remapped (reallocated). These sectors are basically damaged storage blocks - bad sectors - on the drive. NOTE: Bad sectors or bad blocks (also known as reallocated sectors) are damaged sectors that don’t respond to any read/write request. Hence, data can’t be stored (written) or fetched (read) from those sectors. These sectors are marked bad and are re-allocated to spare sectors on the drive - available in most modern drives.Ĭaution: File fragments stored in a bad sector become unreadable, which leads to data corruption, file system damage, and disk errors. When the bad sectors are remapped, the value of the reallocated sector count also increases. But when there aren’t many spare sectors left on the drive for remapping (reallocation), you see an increase in Current Pending Sector Count attribute value and a warning.Īs the number of sectors pending for remapping increases, the chances of drive corruption and failure also climb up significantly. The drive may turn RAW or fail anytime if timely and appropriate actions are not taken - causing an irreversible data disaster.
