Hey Folks, After my macbook hard drive kindly failed on me, I ordered a new Seagate Momentus 5400.5, 320gb hard drive. I popped that sucker in this afternoon and began to start up my macbook with the OS X disc 1. Everything was going smoothly, except that it can't find the hard drive. It is recognized under my disk utility, but when I click to partition it, select options, select GUID, click 'OK', I can neither Name it 'Macintosh HD' or do anything else. I can't proceed with anything because when it asks me to select a HD, the HD does not show up. Again, everything works except that the hard drive is not found. I pulled the hard drive out. Made sure the screws were alright. Made sure everything was all snuggly, and yet it still won't work. Any suggestions? I'm going to bring it to a mac store in town... hopefully they'll know what to do with it.
