So what I did here is create a applescript app that we run before we start imaging with casper imaging. I saved the file as an application thus it can run without applescript editor.
Sorry for my lack of commenting on what is done. See if you like it and maybe you might be able to offer some improvements.
do shell script "diskutil list | grep /dev"
set Drives to paragraphs of result
set FullList to do shell script "diskutil list | awk '{print $1 $3 $4}' | sed 's/#:NAMESIZE//g' | sed 's/[0-9]://g' | sed '/^$/d' | sed '/disk[0-9]/ i\
'"
set selectedDrive to (choose from list Drives with prompt "" & FullList & "
Which drive would you like to format? By default, you should format disk0" without multiple selections allowed) as text
if selectedDrive is equal to "false" then
display dialog "Exiting Program"
error number -128
end if
set SkynetRemoval to display dialog "Are you sure you want to format: " & selectedDrive buttons {"Yes", "No"} default button 2
set SkynetRemoval to returned of question
Removal(selectedDrive, SkynetRemoval)
display dialog "Drive: " & selectedDrive & " has been formated"
on Removal(selectedDrive, SkynetRemoval)
try
if SkynetRemoval is equal to "Yes" then
set Finished to do shell script "sudo diskutil partitionDisk " & selectedDrive & " 1 gpt jhfs+ "Macintosh HD" 100%"
end if
if SkynetRemoval is equal to "No" then
display dialog "Almost destroyed the world....."
end if
on error
do shell script "diskutil unmountDisk force " & selectedDrive
do shell script "diskutil mountDisk " & selectedDrive
end try
end Removal
Enjoy!
