I have 10.6.8 on  MacBook Pro.  When I try to eject my 1TB external hard drive, I get the error message “one or more programs may be using it.”  When I tried to eject it from Utilities, it said that “it could not be unmounted.”  What’s the safest way to unmount it?  Can I just shut down my laptop and then turn off the external hard drive after the computer is shut down?

MacBook Pro, Mac OS X (10.6.8)
