    For quite a while now some of my external hard drives have not worked when directly plugged into my Macbook Pro (Mid 2012 running 10.8.5). They work perfectly when plugged into a USB hub and then into the macbook but not directly to the mac. Standard small USB flash drives work fine straight in to the macbook, the real problem appears to be USB 3.0 hard drives. These will not show up on desktop or disk utility unless I plug them in via a USB hub (which is USB2.0). The hard drive format doesn't seem to be important, currently my Mac OS Extended Time Machine backup HD is only working through USB hub, and my MyPassport WD external drive is NTFS and hasn't worked directly into the Mac for a while now.

    Normally this is not a big issue, but when I am on the go it is useless to carry a USB hub around along with a MyPassport hard drive! In addition, there are times, such as when backing up, that I want the speeds offered by USB3.0 from my macbook to my hard drive.

    What could be the problem? I run NTFS for Mac OSX, not sure if that would cause an issue with the direct connection.
    Please help, this one is grinding my gears!

    Thanks

    Perhaps a power issue. Do the drives work when powered by an AC adapter? I don't have any issues with Hitachi USB 3.0 drives, but I also have a 2013 rMBP.

    One of the drives I use is an unpowered device (powered through USB) and the other is a HD dock so that uses power. Both fail to work via their USB 3.0 cables straight into the macbook. I wonder whether there is an issue with the USB3.0 drivers on my MBP?

    Are you pushing the USB plugs all the way in? There are additional pins with USB 3.0 that require you to fully push the connector into the socket on your computer.

    I can definitely be sure that I am plugging the HD in properly.
    Seems like this is a known problem with Macbook Pro USB3.0 ports, lots of people have had issues before. In terms of fixes, doesn't seem to be too many reliable ones :(

    Specifically, which HD dock are you using?

    Have you tried switching cables around?
