So I found this old 3.5" HDD lying around at the house, seems to me it was from our old home PC from 2012,
Connected it and it was empty, ran Crystal Disk to check it and it looked something like this:


Can anything be done to fix the sectors, or can I make it so the HDD never accesses those sectors so it won't crash? also, would it give any sell value or should I just throw it away?
 
Bad sectors is a physical defect on the surface of the disk thus cannot be fixed.
HDD will not access those sectors once the pending sector count goes back to 0.

Your HDD never shows full space in windows because it has hardware reserved space just for this purpose, to replace bad sectors with new ones from reserved space.
If pending sector count doesn't go to 0 or bad sectors keep increasing that means the disk has gone faulty or has exhausted the reserved space already thus is unreliable and should be discarded.
