Sorry, I misread hdiutil's man page and thus didn't go much further... in fact, hdiutil doesn't require stdin to be a tty for its -stdinpass option to be effective.

The reason here is that, when invoked from "do shell script", the shell is by default in a posix-compatible mode, and the "-n" option isn't recognized by echo. One may for example make use of printf (which is anyway the recommended substitute to echo nowadays):

	do shell script "printf 'abcd' | hdiutil attach -stdinpass " & the result

And yes: where do you take the password from? :-)

HTH,
Axel
