I'm trying to hook up my WD 3.0 TB SATA hard drive to a SATA adaptor. It's also a 3.0 USB drive and the connectors look like those on Western Digital's page here http://wdc.custhelp.com/app/answers/detail/a_id/5389/~/physical-description-of-data-cables,-data-ports,-and-data-connection-types-for They are the first pictures seen under Internal Connections labeled Port. However none of the SATA cables I've seen fit that port connection. Even the plug they show beside that port with the red cable on it doesn't look from the picture like it would fit. I have that same looking port and that same looking connector and I have tired every angel I can think of to mate them and they simply do not go together. The plug even has notches or cutouts so that it has to fit in only one way but this port is made of slightly slanted to flat tynes or metal connectors that in no way accept a plug like the one pictured. What am I missing in making this hook-up? I've seen Youtube videos of SATA hook-ups and as good a look as I could get of the back of the hard drives in those videos the port is sticking straight out and easily snaps into the SATA plug. Is there a special plug for this drive of mine or some other mystery I can't figure out? Thanks for any help.
