Hi there,
sorry missed this post...
This should do it, I haven't tested it yet will do tomorrow...
Code:
property diskname : "your disk"
tell application "Finder"
if not (exists the disk diskname) then
do shell script "diskutil mount `disktool -l | grep 'your disk' | sed 's/.*\\(disk[0-9s]*\\).*/\\1/'`"
delay 1
end if
end tell
replace the "your disk" with your disk name...
The simplest way is to turn the drive off, then back on again, and it will reappear.
I'll check the script tomorrow...
regards
Ric
