Help with HOMM 4 - can't make working copy

[Marshall4]

I am using CloneCD v4.0.1.6 to make my copy with a Lite-On LTR-24102M CD R/W. It can use the SAO-RAW mode. I used the Universal Backup Instructions for RAW mode. The game won't recognize the CD. I have applied the patch to run without CD and it works, but would like to make the back up CD so I can put the original away so the kids won't ruin it.

I've seen some suggestions to set CloneCD to "Hide CDR Media" - but this is disabled and I can't select it. The manual for CloneCD says it's not available in the US.

Any help appreciated.
