Hi, hoping someone can help me with what is probably a silly question but I can’t seem to find an answer online.
i decided to have a go at opening up my sony vaio desktop pc to replace the failed hard drive.
I removed a seagate barracuda 3.5 inch 500gb drive and ordered a western digitalBlue 3.5 inch 1tb sata drive. But i am confused because the new drive has an 8 pin socket where the old drive had a 4 pin socket. Im afraid to open the new drives clear packaging in case I’ve bought the wrong thing.

can anyone advise?

Ah, I understand now. I assumed that was the socket that i pulled th smaller connector out of, but i see now that that isnt the case. Thanks for your help. Much appreciated.
