Removing partition from external HD

I have an old MacBook Pro HD (Mid 2010, 500GB) that I bought an enclosure for and all works great, except that the drive was partitioned 400GB for the Mac and 100GB for Bootcamp. Now when I plug in the drive as an external, both partitions are showing separately. I haven't had any success erasing the drive through Disk Utility to remove the partition and restore it to a single 500GB drive. Does anyone know how I can erase this hard drive and return it to a single partition?

Thanks in advance!

MacBook Pro, OS X Mavericks (10.9.2)

Select the ENTIRE Drive BY Hardware-name, and choose ERASE. The defaults of GUID partition Map, MacOS HFS+ Extended (journaled) should work for ever purpose, unless this drive is for interchange with Windows.

If using recent version of Disk Utility Volume-view is the default, and you must choose Device-view to do this.
