1. Is there a way to add multiple external volumes to this applescript? For instance I have a "Time Machine" volume and an "External HD" volume both connected via USB... I'd like to just eject both if both are present, or just one if only one is present.

2. Also, is there a way to get the script to do the same with Network attached volumes?

I have created my own AppleScript to mount (but not unmount) my HD attached to my AEBS. It'd be great to have one ultra script that mounts/unmounts any volume (network or directly attached via USB/FW)! :)

Here is my own AppleScript for the mounting the network volume:

try
mount volume "afp://Time Capsule._afpovertcp._tcp.local/External HD" as user name "Anthony" with password "password"
on error
return
end try

-- mount CIFS shares.app
-- D Zurn
-- Edit the section below to add the specific shares you want to mount whenthe app is run.
-- The list of mounted volumes is good, the list of failed mounts sometimes includes 
--    mounts that really DID succeed. So, there's that.
-- After any share fails, you can say "yes" to the question to open the Terminal so you
--   can try to determine why it might not work. 
-- The script also opens the Volumes folder to see if there are 'failed' mount folders 
--   from previous attempts, cluttering up the folder.

-- No attempt is made to remove failed mount folders, as it's too risky for a simple Applescript.

this worked for me but it doesnt seem to spin the drive down like it does when I eject manually from the finder.

anyone else have this problem?

You can replace

awk '{ print substr($0,69,9) }'

with a cleaner

awk '{ print $NF }'

This command will do the same work (i.e. get the last word of the diskutil output line) without the need to specify the starting column and the lenght of the substring ( that could be different in future releases of diskutil).

Whoa thanks! I wasn't aware of this. I know nothing about how "awk" works, I just looked at some example code and hacked it until I got the output I wanted.

Nice little script, however it seems like others have this base covered: the free iMount and MountnuoM available on MacUpdate; FreeSpace Tab, QuickDisk, and several others on the MAS.

BTW, on MacUpdate, there is also Semulov (Volumes <--- Semulov: quite clever...), which (un)mounts both local and network drives.

Thanks, I was not aware of these apps. However, iMount and MountnuoM don't have a menu item or a keyboard shortcut to mount a specific volume, and FreeSpace Tab, QuickDisk and Semulov can't mount unmounted volumes.

I haven't yet tried the other apps, but Semulov can definitely mount unmounted local volumes: there is an option in the preferences for showing unmounted volumes (and it even shows the Lion Recovery HD!); however, it doesn't seem to remember unmounted network volumes.

My mistake, sorry! I didn't notice that option.

i have a caldigit raid 5 which i accidentally initialized. i want to recover my data back. plz tell me a way. list of command i need to follow.

I have basically the same need for the same reason. I have a MBP 13 2.8 running 10.7.3. I have added a SSD as the primary drive and moved my regular HDD to the optical bay. Most of the stuff I do is on the SSD, but it is nice to have 750 gig of extra storage. However I don't like the extra heat and the slower performance when the HDD is mounted.
My solution was to write a quick script (In Bash because I am old school and not much of a programmer to start with). I called my script mount_HD and it reads like this..


bash-3.2$ more mount_HD

____________________________________
#!/bin/bash

diskutil mountDisk Data_Storage
exit
_____________________________________
I also have an unmount utility as follows..

bash-3.2$ more eject_HD
_____________________________________
#!/bin/bash
diskutil unmountDisk /Volumes/Data_Storage && exit
______________________________________

For each script make it executable like this...

chmod +x {scriptname_here}



For each of these scripts I put them in a directory, made the directory part of my path search and then made an alias of the scripts and dropped it on my desktop. Now I can click the 'Eject' item to unmount, or the 'Mount' button to mount the drive. This is surely not as robust or elegant solution as the other possible solutions offered here, but I think easy to set up on just about any Mac. If you want the terminal session to close the window after it runs the script you can adjust that in the preferences for terminal (Which I did as I rarely use terminal for anything other than running this kind of script). Also you can make the 'unmount' item a startup item and automate the configuration of your system which I did in order to keep the HDD unmounted unless I needed it.

Happy scripting!

This time for sure!

The original script by Swordfish doesn't work for me (10.6.8). nickv2002's version does work, but only for the couple of USB devices I've tested it with. My main Firewire device gives a "cannot be found" message. I wonder if that's because there's a non-English character (ã) in its name. Any idea? I have not a clue how Apple script works...

There's a typo in the script "{ print $NF }' }" should be "{ print $NF }". (without the quotes)

This helps, I can unmount the volume, but I still get a "not found" when I try to mount it again.

I have tried the following script in AppleScript Editor.app on Mac with OS X 10.8.3 (Mountain Lion) and it does unmount PenDrives, but not the internal iMac disks when booting from an external SSD, which is what I want:

-----------------------------------------
set diskName to "Macintosh HD"
tell application "Finder"
if disk diskName exists then
eject disk diskName
else
tell current application
set deviceLine to (do shell script "diskutil list | grep \"" & diskName & "\" | awk '{ print $NF }'")
if deviceLine = "" then
display dialog "The disk \"" & diskName & "\" cannot be found." buttons {"OK"} default button 1 with title "Error" with icon caution
end if
set foundDisks to paragraphs of deviceLine
repeat with i from 1 to number of items in foundDisks
set this_item to item i of foundDisks
if this_item contains "disk" then
do shell script "diskutil mountDisk /dev/" & this_item
end if
end repeat
end tell
end if
end tell
-----------------------------------------

How to fix it?
Thanks.
