I tried to create a maxi image:
- Created a normal image from CD 1 => image is accepted by NFSMW/SD4.

- Zeroed out the data part => "Insert correct CD"

- Restored the image => image is accepted again (wasn't luck or random)
- Zeroed out just the content of the big ZIP file "0_compressed.zip" => "Insert correct CD"

The error message appears quite quickly, so SafeDisc shouldn't have done a CRC check.
Does SafeDisc check the data with a kind of spot tests?
