I have a MBP with the 160 gig had option - of the 149 gigs that are usable, about 38 are free and I haven't created any partitions. This computer is coming up on its third birthday. I wanted to install XP on boot camp, so I got a copy of windows, printed the guide and sat down to work. Off the bat I got the following error: (having image issues - the error says "Back up the volume and format it as a single OS X Extended (Journaled) volume and try again restore your information and try again) I then tried a few things: 1. In disk utilities I repaired disk permissions/verified disk (no issues)/erased free space and tried again. 2. Again in disk utilities, I tried to create a simple 5 gig second partition on the drive to see if I could do it outside of boot camp assistant. Trying to create a second partition caused this error to appear: (having image issues - the error says I can not creat a 2nd partition) I am not sure what to do next. It seems odd that a drive with 38 gigs can't add a five gig partition. I was thinking of doing one of the two things: 1. Reinstall OS X and restore from boot camp; or, 2. Buy iDefrag and defrag the disk. Does anyone have any thoughts or alternative solutions? Thanks.
