    I'm trying to erase and reformat an external hd, i bought a new one for my macbook and this is the original hd from it i put in a new housing. when i try to format it in disk utility it gives me an error message that says it can't unmount the drive to erase it, any clues?

    Worst case? Reboot and all should be well. An application or file from that drive is probably in use.
