Windows On Mac :: Cannot Make BootCamp Partition - Error Message

To make a long story short, I cannot get past the stage in the Boot Camp install process where you make a partition on the hard drive for Windows. I get this error message: The disk cannot be partitioned because some files cannot be moved. Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again. I do not have a removable hard drive to back up my data on. I've got two flash drives that I put my most important documents on but that's it. I can use my IPod Nano to store my ITunes library until this gets figured out.

The only data I would really lose would be my firefox information, though I did get the book mark history, my video game saved data (4 games), and programs like Word 04, Flip4Mac, and other miscellaneous gadgets. I have already shelled out $80 for the Leopard upgrade and $120 for XP. I have no other need for a removable hard drive and as such I will not buy one. I just got off the phone with Apple Tech Support, one hour of it, and after trying repairing disk permissions and other Disk Utility functions we got nowhere. I tried booting from the Leopard disk and doing the same Disk utility repair/repair permissions to no avail.

Varying the size of the partition had no effect. I tried wiping the free space on my hard drive via Disk Utilities and that did nothing. I have plenty of room on my hard drive, it's 120GB and I have a shade over 60GB remaining. The information on "Mac HD" is as follows:
Mount Point :/Capacity :111.5 GB (119,690,149,888 Bytes)
Format :Mac OS Extended (Journaled)Available :62.4 GB (67,002,867,712 Bytes)
Owners Enabled :YesUsed :49.1 GB (52,687,282,176 Bytes)
Number of Folders :135,138Number of Files :623,284

During the rebook with the Leopard CD, there were apparently some disk permission errors. During the repair permissions process it appeared they could not be repaired but were modified or something to that effect. I just ran another -verify disk-verify disk permissions-repair disk permissions and these errors did not show up. A subsequent attempt at partitioning failed. I was directed to call tech support tomorrow AM and am supposed to ask for someone in 'Tier 2', but I'm hoping someone has some ideas that do not including wiping my entire hard drive and starting from scratch. Particularly since I don't know if that will actually work
