    Select the Drive itself (not one of its partitions) in the list on the left, go to the Partition tab, and click the Options... button down below the graphical representation of partitions. You should be able to select APM, GUID, or MBR from the dialogue that appears.

    Unrelated, but I just noticed that it looks like Leopard's Disk Utility can repartition on the fly now?

    Os X 10.4.11 (intel) Disk Utility Has No Partition Tab!

    why am I the only one on the face of this earth to NOT HAVE THE PARTITION TAB ON MY DISK UTILITY-OS X 10.4.11?

    Is the GUID the same as a DOS Drive format?

    You won't see the partition tab until you select the drive (top level drive, not a named partition) in the left pane.

    If you still don't see the partition tab, something is wrong.

    Its because Apple only introduced that functionality into the Disk Utility for Leopard and Tiger got left out.

    Option button grayed out

    The option button will be grayed out until you select a Volume Scheme above. Leaving the Volume Scheme as "Current" will leave the option button grayed out.
