macOS How to list all unmounted disks/volumes?

[?gruebel?]

Hi all

Is there a way to list all unmounted disks/volumes with AppleScript?

Thanks for your help.

This should do the trick.

do shell script "diskutil list"

This should do the trick.

do shell script "diskutil list"

Thanks, it works so far. But how to go from there . . .

p.ex.

set all to do shell script "diskutil list"
set one to choose from list (result)

gives
/dev/disk0

How can I get the name of the disk/partition and how can I mount it?

Thanks a lot for your help. I'm eager to learn.

I found this that should help you.

Also, I know a lot of forum members use the fee app Semulov to manage volumes. Might be all you need.

Here is a script that will mount/unmount all external drives

oh well

Thanks a lot for the input

Interesting scripts, food for brain.
But I don't want to have all disks mounted/unmounted.
I prefer to have a list presented to choose the one I want to mount or unmount (without having to pre-difine all my disks in the script).
I don't know if that's possible. - I haven't found any hint in the man page for mount/unmount that you can show/list unmounted disks.
OSX disk utility shows unmounted disks - but unfortunatley it's not an scriptable app.

Anyway, thanks and greetings.

Possible with Objective-C/Cocoa

I prefer to have a list presented to choose the one I want to mount or unmount (without having to pre-difine all my disks in the script).
I don't know if that's possible.

If you can write a little Objective-C it isn't that difficult to call Disk Utility and parse its output ( possibly starting with parsing based on CR( carriage return ) using either CFStringCreateArrayBySeparatingStrings() or its similar Cocoa NSString componentsSeparatedByString: ) and put it in a tableview. Disk Utility could be called with a pipe or using a Cocoa NSTask. Disk Utility identifies all the volumes but AFAICT doesn't distinguish unmounted from mounted. That would take additional code. btw: since you apparently are looking for an Applescript solution, I didn't post code.

Another approach: use Apple's DiskArbitration calls for volume information. ( i.e. #import <DiskArbitration/DiskArbitration.h> ) and register for the NSWorkspace notificationCenter. Process the notifications you are interested in using NSWorkspaceDidRenameVolumeNotification, NSWorkspaceDidMountNotification, NSWorkspaceWillUnmountNotification and NSWorkspaceDidUnmountNotification and update the tableview accordingly.

Here is a link for DiskArbitration code: https://stackoverflow.com/questions/11633425/get-a-list-of-unmountable-drives-using-cocoa. You would need to retrieve different keys from the dictionary ( descDict ) as shown in this code but the basic approach is right. HTH.

Hello briloronmacrumo

Thank you for your effort. Your tips are a bit over my level of knowledge. But I'll to follow your hint.

That's the way I'm doing it now . . .

--- unmount - mount partitions
set all to paragraphs of (do shell script "ls /Volumes")
set w to choose from list all with prompt "wich one?" cancel button name "or activate?" OK button name "go away" with multiple selections allowed
try
	repeat with teil in w
		do shell script "diskutil unmount `diskutil list | awk '/ " & teil & "  / {print $NF}'`"
	end repeat
end try

if w = false then --- if you press "or activate?"
	
	set Part to display dialog "name it!" default answer " " buttons {"none", "this one"} default button 2
	set this to text returned of Part
	set butn to button returned of Part
	if butn = "none" then error number -128 --- Cancel
	if butn = "this one" then
		try
			repeat with wakeup in this
				do shell script "diskutil mount `diskutil list | awk '/ " & this & " / {print $NF}'`"
			end repeat
		end try
	end if
end if

You could also use AppleScript to look in "~/Library/Preferences/com.apple.finder.plist" dict "FXDesktopVolumePositions"
Probably not what you want, but it'll give you a list of everything you have ever mounted.
