Jettison folks 2007, Magnum opus, be moving, offers poisoned commentary on the film industry. It's a honey industry. The artificial boundaries we put up between ourselves and those around us, as well as the true meaning of friendship, romance, and following your dreams. Install Jettison from Mac App Store. Use sleepwatcher to unmount the external devices before system go to sleep. But for me, install Jettison is not free of charge, and this application will place icon on the right corner of the statue bar once get installed, which is not a good solution from my point of view.

Jettison automatically ejects external disks from your Mac before your computer goes to sleep. Simplify those last few seconds when you grab your MacBook and run out the door. Just close the lid and Jettison will automatically eject your backup drive, iPod, or whatever is connected so you can safely unplug it. Say goodbye to 'disk was not ejected properly' errors and waking your computer back up because you forgot to eject everything.
Jettison even makes sure that Time Machine backups and file server volumes are properly shut down before they're removed. Your backups and shared files are safe and sound.
And what if you decide not to leave, and open your MacBook back up? Jettison will check to see if your drives are still connected and will mount them back on the Desktop if they're there.
Compatibility: OS X 10.9 or later 64-bit
