    Ok, this may be the wrong forum section for this, but seeing as it's occuring on my MacPro and there are generally more advanced users in here,

    I have a 640GB WD Black hard drive in my computer, and that I had accidentally formatted during my creation of a XP boot camp drive (I have another hard drive in the MacPro with this present)

    At the time I lost a majority of my media and had to rerip it all (learned my backup lesson there)

    So when it was reformatted it was changed from OSX extended journaled to MS-DOS Fat

    I then used the drive to store the media on again as I reripped and pulled some from Time Machine.... I kept running into problems where some files would not copy over

    So I reformatted a different drive and copied all the media to it, which fixes the other issues, and now I'm trying to reformat the MS-DOS 640 GB drive back to osx extended journaled


    When I use disk utility I select the drive, and change the volume format from MS-DOS (FAT) to Mac OS Extended (Journaled) and click Erase

    ......and then it stops and says "Disk Erase failed Disk erase failed with the error: File system formatter failed"

    I tried googling, any ideas?

    I managed to do something like this last week, though I was moving a HD from one system to another.

    Ditto on the good tip! I just plugged in a 2TB Seagate Exchange via USB. It would not allow me to re-format the usual way.

    Changed the partition option and VOILA!

    Thanks for the help.
