Hello, I'm running a MacBook 2006 Core Duo, and need to partition my iPod Classic 80GB into GUID. However, when I use Disk Utility, it pops up saying, "Disk Utility internal error. Disk Utility has lost its connection with the Disk Management Tool and cannot continue. Please quit and relaunch Disk Utility," after which my only choice is to close Disk Utility. What I also find odd is that I am in no way able to partition my HDD either, even though there is a large amount of space to do so. All my choices are grayed out except for the Volume Scheme drop down menu and Options button, but they unlock no other options regardless of what I pick. Any help would be grateful, I haven't found an answer anywhere else.
