Q: Disk Erase failed with the error:  Couldn’t unmount disk. Running Mavericks

I am running Mavericks OX 10.9.1 and am trying to erase an external hard drive that has been partioned. I keep coming up with the error message "Disk Erase failed with the error:  Couldn’t unmount disk." Any suggestions?

iMac, OS X Mavericks (10.9.1)
