If your drive is not supported, make sure to download the latest version at HERE
If it"s still not supported, you can try supporting it "generically". (This will require at least version 4.11 b119 released 3/22/06)
If that doesn't fix the problem, and you are using Windows XP, you can try changing the IMAPI setting. To turn off IMAPI, open MP3 CD Burner, click on the File menu and select Preferences. In the CD/DVD Burning preferences, check or uncheck the "Use IMAPI for burning" option.
Finally, if you don"t have Windows XP or you've turned IMAPI off and it doesn't work, you can go into the General preferences and try it with and without the "Acoustica ASPI" option.
