Great app for Firewire external drives with Yosemite/Mavericks

I’ve had sleep and mounting issues with Firewire 800 external drives since upgrading from Mountain Lion to Mavericks on my 2011 Mac mini. USB drives would sleep OK but Firewire drives would stay spun up unless ejected prior to sleeping the mini. When coming out of sleep the mini didn’t remount Firewire drives consistently. When Yosemite came along I did a clean install and still had the same Firewire issues. My other Mac mini (late 2009) is still on Mountain Lion and has zero Firewire issues so whatever this is it started with the Mavericks OS. Manually ejecting/remounting drives was a pain so I ended up just shutting down whenever I was done with the computer. I lived with this problem for 1.5 years as neither G-Technology nor Apple had a solution. The Mountain app (amongst its other features) now has my drives working like they should.

The Mountain app has resolved the problems with Firewire connected drives so I highly recommend it. I use the "Unmount All and Sleep" feature daily, it unmounts and remounts both USB and Firewire drives consistently. Now I don’t have to worry about my G-Drive staying spun up when the 2011 mini is in sleep mode!
