I just upgraded my Falcon JTAG they had to a new Trinity Slim and did the RGH on it and yesterday I went to hookup the 1TB they had in the other console and it wouldn't fit. The original HDD is 9.5mm and the 1TB is 12mm. Has anyone else done this and if so how did you get it to connect?

I got it. I removed the screw from the hdd cable and put a piece of paper on one side and put the screw back in and it is at an angle now that accepts the hdd now. I also had to bend the hdd.mount bracket on top just a hair so it would push the hdd. Down.

Antman, I know you said you got it, but you shouldn't really have to do any kind of modification, it should slide right in. I put some masking tape on both sides to help pull out easy after closing everything up. The new WD10JPVT 1TB drives are 9.5mm, but this one I have here is the 12.5mm model
