Can anyone tell me if I can put a Hard drive from a 2008 15" MacBook Pro directly into a new June 2009 13" MacBook pro without erasing the drive and reinstalling OSX
You can. I moved my hard drive straight from my white MacBook to the Unibody one, and it was fine. I do suggest to do reinstall and the restore from a time machine backup anyway. Because you want to have all the correct drivers and stuff for the new machine that might not already be included because the hard drive was used in a different computer.
I think you may be right on this. It could be missing some drivers possibly?
Your initial question was whether or not you could just pull your drive and put it in the new machine - to that question, yes you can. You could also do a time machine restore as well. Time Machine would be easier and require less "surgery." I'd probably try the Time Machine approach, and if I encountered any errors, I'd just swap drives.OK. Thanks for the replies everyone. So, if I am understanding correctly just make the switch. OSX is up to date. Should I do a full time machine install? Thoughts?
