So I have a older seagate barracuda 500g 7200 rpm hard drive. My old pc was having Bsod issues and random shut downs and alot of other issues so I decided to take it apart and salvage what I could for my new build. I just want to know what the chances of my hard drive being bad and if I'm better off buying a new one. If it is reuse able then can I erase it fairly easy?
