I think it's a Seagate 500GB SATA. The drive itself works fine, it's just the network speed when it's in.

How do I ground it? It's screwed into the case in a 3.5" bay, so are you saying I need to jam a paperclip somewhere special between the HDD and the part of the case it's screwed into? So, the metal top part of the HDD case and the metal of the 3.5" bay?
