    I've been wanting to nondestructively partition my Emac harddrive for a while so I can have both OSX Panther and OSX Tiger. I am currently using the latest version of OSX Tiger.. 10.4.11. I tried diskutil, and I received an error when I tried to do "diskutil resizeVolume disk0s10 limits".. Disk0s10 was right next to "Apple_HFS Macintosh HD /dev/disk1" with a 38.0 GB size when I did a "diskutil list".. I had an error that said:

    Error obtaining resizing information
    Resizing encountered error Could not modify partition map (-9986) on disk disk0s10 Macintosh HD

    Then I tried disk0 instead of 0s10, which was right next to "Apple_partition_scheme" that had a 38.2 GB size.. I got:

    Volume format does not support resizing.

    Before I did this, I disabled Journaling just in case that would help. But here's a fun fact: This was my third time attempting this, and first time that I disabled Journaling. So that had nothing to do with it. Some nice facts about my Emac is that it's the 700mhz model. I can't read or write DVDs, but I can read and write CDs. I tried ipartition, but to burn it on a CD required a DVD or a backup drive.. or a magical CD that has a size of over 2GB. I have no external harddrive or a USB flash drive. I feel screwed.

    Im not sure if you can actually resize system partitions in Tiger. AFAIK that capability was only added in 10.5 Leopard (which will run on your eMac, as I have it on my eMac/700).

    Hmm.. Is Leopard running well on your Emac? I'm thinking of installing it with Leopardassist..

    The ability was added in Tiger 10.4.6, but (i believe) any volume to be [non-destructively] resized would itself need to have been *originally* initialized (formatted/partitioned) with the corresponding updated version of Disk Utility (i.e., Disk Utility v10.5.5 or higher).
