Hey there, I'm running Alfred 3.3 on El Capitan 10.11.16 on a mi-2012 Macbook Pro. I replaced the SuperDrive with a hard-drive. Worked fine until recently : i would use a workflow to automate the mounting of the disk, and then use the "Eject" function via Alfred to quickly eject the disk and avoid the sound of this 7,200 rpm hard drive when not needed (how did we do before having SSDs ?). However, "Eject" will no longer recognize the hard drive. Every other removable media will appear, but not this internal drive. Does anyone have an idea to fix this ? I would appreciate your help. Thanks for reading, Pierre
