Boot Camp: Create Partition Error – Files cannot be moved

Recently I was about to install a Windows 7 beta using Boot Camp on my iMac, but it did not succeed due to an error. I was setting the Windows partition to 80 GB with plenty of free space available.

Then I got this error, namely “The disk cannot be partitioned because some files cannot be moved”:

But I did not like the idea of formatting my hard drive due to fix the issue, and make Boot Camp work. However, I found an other solution to the problem, namely installing tool to defragment the hard drive. Defragmentation is not something you usually do on a Mac, but here it came in handy. I found these two tool to do the trick:

What the tools basically do, is that they are able to moved the files, which for some reason is blocking the Boot Camp Partitioning.

    hi,

    didn’t work for me. after 10 hrs of defragmenting, iDefrag simply told me, that not all parts of the disk could be worked with and large parts of the hdd are still deep red. I used quick-mode (on-line) because the other four algorithms didn’t work (the go-btn just stayed red…). after that the boot camp assistent had the same problem as before defragmenting my disk. what a waste of time! I think, I have to look for another solution…
