    So I ordered the following two things:

    HGST Travelstar 7K1000
    BrainyTrade HDD caddy

    I installed them, booted up and decided not to click initialize when the message initially came up. I used disk utility to create two partitions 1 OSX Extended and 1 exFat. It created the partition table fine, but then gave an error while formating the OSX Extended. Since then I have reformated it 1 giant partition. I try to conduct file transfers to it and it seems like there is a 30 second gap where it will do nothing and then transfer 15-25megs and then another gap. I can't seem to figure out what might be the problem or if I missed something.

    Any suggestions?

    Thank you

    Well I updated the SMC firmware, rebooted and then went back to try to update the EFI however when I open it, it states that it is not supported on my system. I made sure I downloaded the correct version, so I am guessing it is either already running it.

    This means it is either the drive or the caddy. I guess tonight I can pull the drive and put it in an external enclosure at test it that way.
