First of all, this is exactly why SPIN is treating an empty drive identical
to a "blank" CD. This is usually more convenient than seeing the critical
error handler.

If you want to get rid of the critical error handle, you can just install a
dummy one. I can send some sample code tomorrow, in case you need that.
