Key2audio has been tested in 27 drives with Céline Dion's CD (http://www.zdnet.fr/prod/cgi-bin/a_prod.pl?ID=20704) 18 refused to read the CD, while 9 succeeded. For most of these, the CD appears like any unprotected CD, but with some others, it is not directly accessible from Windows, but needs a burning program like Nero or CDRWin in order to be read. About those that can't read the CD, the sympoms are various, from not seeing the CD to freezing the machine through freezing the computer, like with CD-Rom Matsushita CD-ROM CR-594, DVD-Rom Hitachi DVD-ROM CG-7500 or DVD burner Pioneer DVD-RW DVR-104. The burner CD-RW from Iomega ejects the CD after 2 seconds.

Nickname "plex the ripper" points out in EAC's forum (http://www.digital-inn.de/showthread.php?threadid=11599) that Sony drives (DDU1621 above) defeat Sony protection (Key2Audio)... )))
