Hey there, I'm hoping someone here can help me out. A couple days ago I was using my laptop, and it all of a sudden froze with the spinning beach ball. I tried restarting numerous times, and my Mac could not load past the apple symbol and spinner underneath; it will not even boot into recovery mode! I haven't heard any abnormal noises coming from the hard drive, so I'm wondering how I can tell if this is a hardware or software issue. If it's the former, I plan on purchasing a Seagate Momentus 7200 this weekend and installing that. I don't know what to do on the software front-- any ideas? This is on a late 2009 Macbook Pro running the most updated Mountain Lion.
