Hi I don't know if I'm in the right place. I don't know much about hard drives and was looking for some advice. I am helping a friend with his CCTV and the hard drive has died. The one I took out of the cctv was a Seagate pipeline HD .2 st31000322cs and I don't seem to be able to find a new one can anyone recommend a replacement drive please it's to go on a ray sharp CCTV system. Thanks in advance
