Hello,
One of my hard drives, a WD Green 4 TB, has developed bad sectors. I am using it for archiving movies and photos. I do not care about recovering the data, I want to flag these sectors as bad and risk using the HD a bit longer.
The symptoms are that some movies just hang, and only after a timeout of about a minute can the viewing program (ZoomPlayer) be killed. Usually when there are logical errors on the file, like it being corrupted or not finished, the movie just stops, but here it is like the OS is timing out trying to access adisk sector.
I ran Macrorit Disk scanner and apparently it flagged some sectors as "bad". I did not check the SMART status before the operation, after the scan CrystalDiskInfo shows 0x874 "Uncorrectable Sector Count", with a "Current Pending Sector Count" of 0x873.
So now I presume that the bad sectors are flagged as such and the OS will not try and access them? Except these bad sectors are still part of the movie files, and the movie player still hands on them as it did before. So they are not flagged as "unreadable"? I was thinking of testing all the movies, and moving all the bad ones into a directory named something like "_BAD". But this would be rather time consuming, with the long timeouts on each file. If I erase the files, will the OS try and reuse the bad sectors? Or does the flagging as "bad" only work for writing? So if I erase the files nothing will read nor written on those sectors any longer?
(yes, I understand there is a strong possibility that more and more sectors will become bad, no point in starting this discussion here)
