So - It starts out with a key change error in disk utility. Next, I try to repair in Disk Utility but oh no, it doesn't work. So then it shrinks my hard drive somehow and I have 0.0000000 GB left and I can't access the partition from Windows. I can't get my digital downloaded Sims 3 games from there. I've never been so screwed in my life. I had high expectations to finish my work, but I guess I can't now because I can't access OS X. All's I get is this beautiful blue screen with just a cursor. I can backup the hard drive and reformat, but I don't have the $100 to go out and get an external hard drive. I have lots of important stuff on there and I'll fail a couple of my classes without them. I need help.
