Sounds like you need to force it to dismount from the command line.
I think the answer is probably yes as long as your G5 desktop contains an Intel chip. If not, then it is out of luck. I am not sure how long it takes to finish the job between two intel computers.
This is kind of crazy to me. Please consider to replace the CD/DVD drive without a hassle or avoid to waste your time.
