Yesterday, I was trying to install Windows 7 on my 2009 Unibody Macbook Pro using Bootcamp. I selected 40 GB for the windows partition but it was unable to partition it and gave me an error saying something about how bootcamp was unable to move some files. So I opened disk utility and verified and repaired disk permissions - it told me to boot from the OSx CD and fix it that way. So I thought why not reformat the computer while I have the installation disk out. So I pop in the installation disk, boot from it, open disk utility to erase the hard drive and it shows me that I only have 465 GB on the HDD and beside that number in parenthesis is 500GB. Now I'm wondering where did the other 40BG go? I've reformatted the hard drive twice since yesterday and the HDD still displays that the hard drive has 465GB. Shouldn't it be something like 499GB? Anybody have any ideas as to what's going on? How can I fix it, and get the remaining 40gb. I remember when I first got my laptop and installed Snow Leopard, it showed me that the harddrive had 499GB on it and went down to something like 489 after 11gb of installation. How come it's showing me 465gb now? Shouldn't it go back to 499gb since I've erased the hard drive and reformatted?
