Death of a Hard Drive

I have some sad news. My laptop has died. The error code tells us the hard drive is dead. We're debating on whether it would be better to buy a new hard drive or a new computer. What if there are more problems than just the hard drive. I'm thankful that I backed up all of my photos in December, so I didn't end up losing all that much. I've been lost this morning without my computer, and now I'm borrowing Alex's computer to post a blog... Hopefully we will figure out what do to and I'll be posting from my own computer again soon...
