I am trying to partition the hard drive on my mac and install windows so that i can run windows based programs and other reasons, but my mac is not new and it is harder than brain surgery to locate all the files i need to back up and the ones i dont. when i open boot camp, it starts partitioning the hard drive for a few minutes and i get the 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 single Mac OS Extended (Journaled) volume.  Restore your information to the disk and try using Boot Camp Assistant again. i cant format the disk because the computer only has one disk. and i cant format it. Please help!

iMac, Mac OS X (10.5.6)

    A very good way to handle this is to buy CarbonCopyClone ($40 download) and an external drive.  Then clone your startup disk to the external, and clone it back.


    What has happened is that after several years you have created so many tiny unused disk spaces (some only 1 or 2 blocks large) that OSX cannot relocate everything and make room.  When you "clone back", all files will be in a large section at the bottom of the available disk space and there will be plenty of room for BootCamp.

    Thank you very much. i have an external drive that holds about 300 gb but i filled it with alot of data on my computer to speed up the resolution for a simulator i have gone all pro at. I just need to wait until i get enough money for the download. Thanks again.

    You can download a 30-day free trial.  It will make a clone, but will not take any "updates" until you pay.


    That at least gives you an immediate clone ability, even if the complete solution takes time.
