I have a MacBook Pro which I regularly dock to an external monitor.
I have my mouse, keyboard, and iPhone dock, and an external hard drive connected via a USB hub so that I only have to make one USB connection when docking.
The external hard drive is used for Time Machine backups. Every time I undock, I simply unplug the single USB cable. Unfortunately this causes a warning message that says that I should remember to eject the external hard drive before unplugging it.
What I would like to know is if there is a way that I could have it automatically eject the external hard drive each time after Time Machine runs.
I usually undock and redock at least once a day so the next time it is docked, the drive will be re-mounted and then Time Machine could run while the system is docked.
