External Hard Drive Not Showing Up on My MacBook, How to Fix?

I've had my external hard drive for my MacBook Pro for about 4 months. Today I went to plug it in via USB, it was working fine, then I accidentally unplugged it without ejecting it. Now it won't show up on the Desktop or the Finder. I used Disk Utility, and at first, it showed up there, I selected to repair it and it said the hard drive can't be repaired. Now it won't even show up in Disk Utility. I have a lot of pictures and video on the hard drive I can't lose. Any ideas of what to do now?
