    I really don't know what is going on.

    I tried both ports on my rMBP, it powers on, spinning nicely but nothing available in disk utility or in startup menu.

    The driver is just fine, it works on my late 2010 MBA and Early 2008 MBA, as well as on my PC desktop...

    Please don't tell me that retinaMBP does not have enough juice to run this external drive... :(

    Just loaded up a Toshiba usb 3.0 last night and the rmbp detected it without a problem. However, it wouldn't see my Seagate freeagent 3.0, and disk utility told me it needed repairs. I returned it to costco instead and will use my Toshiba for now. The Seagate did what you describe with yours, but disk utility would see it, so might try that again?

    Same thing happened with my 2012 13" MBP. It would not detect the toshiba drive, but my girlfriend 2011 MBP 13" would detect it. Both would power it up. But the 2012 would not mount it, nor viewable in the disk utility.

    Try a different cable, sometimes that's the issue.

    Wow... this is really annoying!

    I just tried same drive with a regular micro-usb to usb2.0 cable (from my blackberry) and it works like a charm!

    if I switch cable to the original toshiba usb3.0 cable it only spins and nothing happens...:confused:


    I tried another usb3.0 cable from seagate freeagent external drive already, same thing happening...:(

    You just troubleshooted your own problem. Clearly its the cable, but why is the question.

    If it works with a 2.0 cable then the drive works.

    Try using the 2.0 cable, formatting the HDD, unmounting then trying the 3.0 cable.

    Avoid Toshiba at all cost. There a reason why their stuff is lower in price compared to their competitors. This is speaking from experience.

    Yep. Toshiba 3.0 drives have issues with MacBooks from the start. Google it. Then, return it and get a WD My Passport.

    I have 4 of this 1tb hdd and all works perfectly on my macbooks and pcs. I am not saying they are the best but they just work for me.

    Seagate Go Flex is actually better. The reason is the WD portable drives integrate the ports in a proprietary format so if your connector goes bad, there no way to put the hdd into a different enclosure to retrieve your data. Again, speaking from experience...lol
