Script to unmount a volume at startup

[Ben J.]

Hi, folks.
I know very little about Terminal commands and such, but I know that if I paste:

diskutil unmount /Volumes/AU0039

AU0039 will unmount.
(This is a fixed partition on one of my external drives, probably with some enabling software for windows and such, that is impossible to get rid of. It's 30MB, and it's just annoying to have in Finder and dialog boxes.)

I've been playing around with Automator and Scripteditor to try and make a small script/app that I can put in startup items, so I never have to see that volume again.

I'm shure this can be done easily.

Thanks in advance.

I am not an AppleScripter but did find this:

Automatically Mount External Drive to Clone a Mac » The Appademic

A good example of a simple macOS automation. How to automatically mount external drive to create a bootable clone backup.

So, in your case:

1. Launch Script Editor
2. Input

do shell script "diskutil unmount /Volumes/AU0039"

3. Go to File -> Export...
— Name the file whatever you want (e.g. unmount-ext_AU0039)
— Choose a save destination
— Verify the File Format is Script Application
4. Add the file to Startup/Login Items

I have not tested this on (re)boot to ensure that macOS runs the script and does not simply open the editor.

BINGO!
Thank you MacCheeta3, that was almost spot on, only thing was; I had to save as an application in Script Editor, then add to loginitems. A script would just open the editor.

I restarted just now, and the little annoying volume disappeared after a second or two of the Finder appearing.

(JFYI: this volume was especially annoying because it could not be erased or removed in Disk Utilities, and if you tried to eject it in finder, it would just pop up again. Only way to eject it was thru Terminal or 'Deactivate' in DU.)

Thanks again.
