    Im running mountain lion, With all updates on a 2007 iMac c2d with 2gb's ram.

    My hard drive inventory is as follows -

    MAC OS
    Time machine ( Seagate 320gb ext )
    Media 1 ( WD Elements 1tb ext )
    Media 2 ( WD Elements 1tb ext )
    Life studio ( Hitachi 500gb ext )

    Media 2 is the issue.

    One moment its there, then I get the message about not ejecting correctly ( I haven't ejected the drive )

    I reboot with the drives unplugged, Then replug them in and its there again for a moment.

    All of my ext drives are connected to two powered usb hubs. ( So theyre drawing power from the wall and not my mac )

    If anyone has any ideas I'ld love to hear them please as this is infuriating me no end lol!

    How does it react when its connected directly to your iMac?

    Havent tried yet as I cant get behind my desk until tomorrow now.
    But I will try it and I'm thinking about minimizing the amount of USB devices I
    have plugged in.
