All day Saturday I was having problems with my Macbook Pro laptop. It seemed to be freezing up and I would have to keep re-booting, it was like a Windows pc. Finally around 7:30 pm it just stopped completely, I ran the disk utility and tried to re-install, but it said it was done. After 3 plus years the hard drive finally crapped out. The good thing was I knew that the Time Machine was working every hour, so I would have my data to that point. Before going to bed, I had pulled the hard drive from my laptop and had figured out which replacement drive I was was going to buy today. After picking up a 500GB hard drive for $70,  I had it back in the laptop and was restoring it with my Time Machine backup from 6:23 pm last night. By 4:00 pm, my laptop was booting up and running like normal.
