    I've read up on similar issues but I can't seem to find a solution.

    I bought a 1TB Iomega Prestige drive, it worked great for a few months. Started making loud clicking sounds. Iomega sent me a replacement drive (refurbished).

    I am using it as my time machine backup in Leopard, so it was really just a matter of plugging it in, formating it with the OSX file system and setting it up for time machine.

    When attempting to format from Disk Utility, I get an error (see screenshot).

    Is there a fix to this, or did Iomega ship me a dud?

    (Additional info: I can access it and format it without any problems from Windows 7 based PC).

    The partition table is probably in Master Boot Record, which can't be formatted in HFS+.

    Instead of what you are trying, select the "930GB" drive (the one above disk2s in the source list), and the Partition tab will appear in DU's main window.

    Select the PARTITION tab
    change CURRENT pull down to 1
    click OPTIONS below
    change to your need (GUID for Intels)
    select Mac OS Extended (Journaled) or whatver you want
    give it a name
    click APPLY

    Unless the drive is potentially damaged, this will work.
