I have a 4TB WD Elements that's failing. Areas of the disk that can't be read, etc. CrystalDisk reports a condition Red - Bad, and right now, running CCleaner on it to do a 7-pass wipe to see if it can finish, it says it will take 2067 days, so, not likely.
Is it likely that this issue is the drive itself, the controller going bad, or a combination? Is it worth pulling the hard drive and installing something like a WD Black in it to help improve reliability?
