"Current Pending Sector Count" is a critical S.M.A.R.T. parameter that indicates the number of unstable sectors on the disk drive that are yet to be remapped or reallocated.

A rise in "Current Pending Sector Count" may indicate unstable sectors on the disk drive. If this value increases over time, or you receive warnings/errors from a S.M.A.R.T. scan, you should replace the disk drive.
