CloneCD and Yamaha 4416S

[Robaerus]

Anyone could help me, please?
Somedays ago I tryed to copy Cleo, and I've tried to do it with the Yamaha 4416S as a reader and writer, but...as it starts to copy the image file, the whole computer locks!!! I tried to reinstall the firmware (actually is 1.0j), the new drivers ASPI, to install a newer version of CloneCD (2.7.8.1), but I still have the same problem...
CloneCD works if I use my CD Asus S500, but I see that the copies are able to install the game, but NOT to play it (both Cleo and Zeus, italian versions).So, any suggest?
Thanks for your replies.
