Error resizing volume

[CrArC]

About two months ago I got sick of windows and so bricked it, deleting the partition and using the diskutil resizeVolume command under terminal to pad out my OS X partition to fill the drive they were sharing. Worked fine.

 

Now Crysis Warhead is in my grubby hands I want to shrink the OS X partition and dump windows back on there (having realised it will run under parallels/vmware/crossover on the tenth of Never) but it won't shrink!

 

It gives me the most unhelpful error too:

 

bash-3.2# diskutil resizeVolume disk2s1 260G		(it's a 320GB drive, 140GB free space on partition)
Error resizing volume
bash-3.2# diskutil resizeVolume disk2s1 limits
Error obtaining resizing information

Resizing encountered error on disk disk2s1 OSX: Could not modify partition map (-9986)

 

Useless. It could modify the partition map before, the only thing that's changed I can think of is that it's now been upgraded to 10.5.4 and I did the resize operation in 10.5.2.

 

So I booted off an old installation DVD and it couldn't handle it either. Any ideas? The web is just chock-full of rubbish about needing Intel macs and GPT.

An alternative would be to create a clone image of your windows partition with winclone (free), erase the windows partition via bootcamp assistant and re-create it afterwards.

I don't have bootcamp or anything. What I've managed to do is boot Parted Magic (a distro based on Linux) from a USB stick and reconfigure and resize my partitions that way.
