    Hi all,

    When I bought my Macbook about a year and a half ago, a computer savvy friend set it up. So far as I can tell, he split my hard drive in half with one side intended to be a backup. Now I'm receiving constant notifications that my startup disc is nearly full.

    How do I undo whatever he did and make my startup disc as large as it can be? I've found some answers via Google, but I'm hoping there's another way (in large part because I have no idea how to backup everything and reinstall):


    Why, oh why, did he do this to my computer. It looks as though the backup portion has 41.95 GB available, whereas my regular drive has only 236.4 MB available.

    Thanks for all your help; it is greatly appreciated :)

    Are you on 10.5?

    Can you afford to erase the backup partition?

    If you answer yes to both then go into disk utility, select your drive, click on the partition button1., select the backup partition 2.and then click the minus button3.

    The system partition is not erased in 10.5, a dialogue box should pop up and confirm that.
