Hello all! Well, here I am trying to figure out why when I plug in my brand new HD Samsung ST1000LM024 (https://www.amazon.com/gp/product/B007NVGWV0/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1) it gives me the four lights. I thought I had done my homework effectively and found a PMR drive with low cache to replace. Can anyone tell me if I need to format it, perhaps? I don't want to mess with it too much if I need to return it to Amazon. Thanking all y'all in advance!
