Hi guys I just received my new blackbook and I am loving it. I transferred all my files over from my iMac and cleaned the iMac up so my family can use it as their main computer. The iMac is running Tiger and the blackbook Leopard. Both have 250GB hard drives. I have never had any prompting about a full start up disk before. Both computers have over 100GB free HDD space. I just completed a 'repair permissions' and 'erase free space' in disk utility for both machines. At the completion of this both machines warned me that my startup disk is almost full What does this mean and how do I fix it? Is it an error, since I have 100GB free at least? Thanks for any help.
