However, I could not get it to eject after trying it several different ways by the symbol in Finder, by the Finder menu and by the eject button on the keyboard.
I finally turned the external drive power switch off and received the message that it had not been disconnected properly and may have damage data etc.
How can I safely disconnect the drive the next time I mount it?
Thanks for your help.

There is nothing to gain from explicitly 'ejecting' drives before logging pout, shutting down, or restarting in a normal fashion. MacOS X has a subsystem called 'Disk Arbitration' (primarily the system daemon process 'diskarbitrationd') which mounts drives other than the boot device when a user logs in and unmounts (a.k.a. 'ejects') them when the user logs out.
