If you check the Current Pending Sector Count SMART parameter of your drive, you will notice a raw value of this attribute. The parameter indicates the number of unstable sectors on a hard drive or SSD that are yet to be remapped or reallocated.

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. Never perform hit and trial methods on a failing drive as it may further damage the storage drive and lead to early failure. WARNING: Immediately stop using or minimize use of your affected hard drive.

Reallocation events and reallocated sector counts should also go up.How to Fix Current Pending Sector Count Warningīriefly, the ‘Current Pending Sector Count’ warning indicates imminent drive failure and requires urgent backup & recovery followed by hard drive or SSD replacement. You may see an increase in uncorrectable sectors if it found more. There should be no pending sectors after. This should have forced the disk to relocate pending sectors and be in a safe (for now) state. Phase 3, do another full surface read. Normally this is destructive but you can try to find something that combines 1 and 2: it reads then writes back the same data to the same location. This will pick up any other unknown pending sectors. I'm not sure what tools there are to do this. Otherwise you can kinda force the drive to refresh the whole surface. Basically both are signs part of the drive is on the way out. Data on there wasn't readable without errors. A pending sector is a sector where the drive has detected a growing problem, and will try to relocate the data to a new location the next time you write there.Īn uncorrectable sector is just that.
