So I have a very old mb (P5K) and a 500gb Seagate hdd that I don't know how old it is or how long it was used,when I start my computer it can be heard a sound coming from it that it's like turning off and on,it happened in the past amd after being a genius and just switched the sata wire from the mb to the hdd amd otherwise it stoped for some time but I moved some wires around the hdd this morning to get something that I kept on top of it,btw it's kind of full too
