JAY GEE Level 1 Level 1
Every time I try to partition my hard drive, via boot camp, it fails, and it says the following: 'Back up the disk and use disk utilities to format it as a single mac os extended (jouraled) volume. Restore your information to the disk and try using boo camp again.'

I haven't attempted this for the simple reason I don't understand what it is saying, and why do I need to do this anyway? What has gone wrong?

Thanks in advance

Macbook, Mac OS X (10.5.5)

    There isn't enough free space that is unfragmented.

    You should have a backup before doing anything. So it is just a matter of reformatting your drive and restoring from SuperDuper or TimeMachine backups.

    How do I reformat my drive. I did back up using Time Machine, just before I tried to do it.

    This all sounds complicated. I thought it was meant to be easy installing Windows onto your Mac, using Boot Camp. This doesn't seem that easy to me.

    Well, it's easy if your computer is new. The problem is that when you use your computer for a long time, the data on your Hard Drive gets fragmented (meaning each file has pieces all over the physical drive platter, but your computer knows where all those are, so you never notice the difference).

    The solution isn't so hard, but it will take a little bit of time. First make sure you're all backed up using Time Maching (or Super Duper as someone else mentioned, but that process is different). Then put your OSX disk in, and reformat the entire drive (read: erase) then re-install your OS. When you start the OS for the first time it will ask if you want to use Migration Assistant to restore your stuff, point it to the Time Machine drive. Let it do it's thing and all the sudden you're up and running like nothing happened and your drive isn't fragmented at all. Whoo hoo! Look around on Apple's support site and these forums if you need more direction on what I just said.

    Then, finally, when you use Boot Camp Assitant it shouldn't have any problem reformatting your drive.

    Hope that helps.

    The idea of using TimeMachine is... you don't need to reinstall!

    Also, the Help menu in Disk Utility will walk you through, as do TimeMachine support pages.

    If you have question on how to use TM or run into questions, there is a forum devoted to Leopard TimeMachine.

    I thought Mac OSX didn't need defragmentation because of the HFS+ it uses.

  • The hatter Level 9 Level 9
    fragmented free space is a different issue which HFS doesn't worry about.

    Doesn't need also doesn't mean you can fill a drive beyond 90%.

    You can have all your files unfragmented but not have a single free space large enough to take out and create a partition for BootCamp also.

    Okay, he's right. If you put your OSX disk in, reformat the hard drive, then go to Utilities->Restore System From Backup it will let you select a Time Machine backup and go from there.

    And yeah, good point about HFS and not fragmenting files. The fragmented free space is the issue.

    Just a little question..

    If I got a ekstern drive where I can make a copy to of my leopard and boot from there (using carbon copy or super duber)

    Should my intern drive then be as one partition and some free space to install windows through boot camp, and then copy leopard back to the maked partition, or just one big partition ??

    Know it's not the easiest way, but dosn't have a disk for time machine at the moment, and don't wanna start over from scrath..
