I tried to make a backup copy of MOHAA italian version, using CloneCD 220.127.116.11. Settings used:
Read speed: 4 X (as suggested by ClonyXXL)
Fast error skip enabled
Write Speed: Maximum
Amplify weak sectors enabled
Results: the backup copy works perfectly in the Plextor Writer, but not in the ASUS 50X CD Rom reader.
Anybody else has other tips?
Thanks to everybody.
