i just got a brand new mac mini from apple online store shipped yesterday. It's a 2.53 GHz mac mini. It started up fine. I restored the mac mini with my previous backup from my external Hard drive that was previously connected with my late 2009 15" MBP. I have a seagate 500GB Hard drive and I tried taking it off my mac mini but it keeps saying its in use when I'm not backing up anything. Each computer is using only about 85-90GB of hard drive space and the seagate is showing that I only have 32GB left?! I have another file in the seagate external with movies but thats about it and it only took up 12GB. Whats going on? Should I fresh restore the mac mini?
