I have a Seagate Barracuda 7200.10 ST3250820AS p/n 9B413E-033 Firmware 3.ADG number on chip 100404226. I have found a PCB on Ebay that matches all of the above numbers however their site code is a WU and mine is TK. Does the site code have to match?
Does the site code have to match in order to do what?
It really doesn't matter at all if you're just trying to buy another drive to go into a system with an existing drive. Even if you want to put them into a RAID set it's completely irrelevant - you don't even have to use a drive from the same manufacturer.
