    I have a 1TB external drive attached to my MBP. If I have the drive running when I start up the MBP, then I get the following error:

    The disk you inserted was not readable by this computer.

    If I turn the drive off and then back on, the computer reads it fine.

    I have other external drives and they all show up properly.

    I used Disk Utility to verify the 1Tb and it was ok. I repaired anyway and still ok. I used the erase function. Still behaved the same way. If I try to re-partition the drive (there is only one on it now), I get an error that says unable to write to the last block.

    Advise Please! Many thanks in advance.

    I'd say either bad drive, or the drive doesn't play nice with Macs. Unfortunately some drives that work great on PCs just don't on Macs. Try a different brand drive before spending much more time on this one or the macbook.

    Have you decided between the iPad and Mac Pro yet?
