I have a 320GB harddrive with 95GB free. I boot to a 10.5 disk, open disk utility, and add a 40GB partition. Halfway through the progress bar, though, it tells me that there's not enough space. I'm not sure what it means- I'm just splitting my free space off to another partition- it shouldn't need any extra space.
Any ideas as to how I can partition my drive?
Clarification: this is my laptop's internal drive- the one I boot from. I can't boot normally and partition with /Applications/Utilities/Disk Utility.app.
