Yes, as has been said by me before, formatting a Zip disk with the patched Apple HD SC Setup tool will install standard Apple drivers to the disk, making the machine think it is a regular disk with all the associated attributes thereof, which is really handy because you no longer need any special software to use said Zip disk, and as a side effect of this, it won't be ejected at shut down or restart, enabling one to use it as an internal hard drive replacement.
