I'm new to Windows 8.1, last I used was Vista before I went OSX, and I can't seem to find a way to eject the mounted drives/partitions. With external drives (USB/Firewire) I would normally right-click on the drive letter and Eject would be an option in the popup menu, but that seems to be missing. The only thing I can do is shutdown Windows (not sleep or hibernate) and then unplug the hard drive. Is there any way to eject/unmount the drive without this workaround?
