I/O Error. Incompatible medium installed

[addtamx]

When trying to create an image file from disk for a Wii game I get a message that the device is not ready (incompatible medium installed).

What could be the problem

That happens when reading an original Wii game disc? I'm asking because Wii game discs are protected and can only be read by certain drives, and at a very slow speed

[addtamx]

Yes it is. Is there any information to help me out?
