Applescript to Mount/Unmount A Disk...

--Assuming the name you have given to the drive is "External FW" try this:

set driveName to "External FW"
set driveInfo to do shell script "diskutil list | grep \"" & driveName & "\""
set driveID to last word of driveInfo
--In the following:
--TO MOUNT (use mount to mount just the single volume, if the disk is partitioned, or use mountDisk to mount all volumes on the disk)
--To UNMOUNT (use unmount for just the single volume, or use unmountDisk for all volumes)
--For example:
do shell script "diskutil mount " & driveID & ""
--do shell script "diskutil unmount " & driveID & ""

--I'm assuming you can work this into any remaining
--script you need. The "unmount" can be pretty slow.
--An alternative is:


tell application "Finder"
eject driveName
end tell

--but there's no Finder equivalent for "mount"
