Likely a firmware issue, though it is also understandable why it would happen. We had a batch (a few thousand) office computers at work (around 2010) which included hitachi drives (160 and 500GB, do not remember exact models), on which power loss during active write produced such sectors. Well, the reason i am saying this and the reason i did quite a bit of research on this is - i encountered this in real life. Because that means actual damage exists and it indeed have failed. That's why overwriting whole drive in a situation with a lot of pending sectors but no reallocates will either make them all disappear or force the drive to reallocate them, and once you look at smart afterwards it would be clear if actual damage exists or not.Īnd yes, if write is going way too slow and reallocated sectors start appearing in smart at this point the process can be interrupted and the drive goes to garbage. If it was just data corruption, however, write would be successful, no reallocate will happen and the sector will no longer be flagged as pending. When you overwrite the sector the drive tries to write it and at this point recovering data no longer is a concern, so if write error happens (the sector is bad) it will get reallocated. That can be either because the sector is physically damaged, or because the data is corrupted and since it does not match checksum the drive assumes it cannot be read. What pending and not reallocated sector means is that the data cannot be read. Then overwrite that sector, try to read it again and see it entirely disappear from smart (no pending, no reallocate). Then take a look at smart and see a pending sector there. If you want to do a little experiment - take unused hdd and run "hdparm -make-bad-sector" on it. Only reason for a pending not to continue is physical error. The drive has no reallocated sectors and the data was just corrupted somehow although I am not sure but SMART gives the drive a good status so that's good enough for a bulk game/installers drive. To settle the debates in the comments here is an updated image of crystaldiskonfo. Should I do a hard format (not quick format) as a last resort based on what I read about this specific SMART error?ĮDIT: I reformatted the drive the long way it took about 4 hours it slowed down at some point and continued from there. I tried the checkdisk cmd repair thing and it repaired a lot of files and gave even more SMART errors.This is a game drive and general storage drive so nothing critical and all is backed up to the ccloud. Last week it started with a video file stuttering when playing, then it became a game launching to a round then to said game not launching at all. I have this WD black 2TB HDD DOF: 2017 or so, with about 4 out of 5 years of active use. Just make sure to tag the post with the flair and give a little background info/context.
