    12. CD/DVD writing software does not recognize the drive
    If the CD/DVD writing software displays messaging that no drive is detected, use the steps in this section.
    注 :Disc recording software that comes with HP and Compaq computers are made to recognize only the original CD and DVD drives that come with the computer. If you have added a new drive, use the disc burning software that came with the drive or use the native burning capabilities of Windows 7.

    Upgrading the operating system or installing certain types of software can cause other recording software to lose their connection to the drive. Installing software that can burn discs, some music software, and some DVD authoring/decryption software can cause these types of problems.
    To correct the problem and allow the software to detect the drive again, uninstall the CD recording software, restart the computer, reinstall the disc recording software, and then restart the computer again.
    注 : If the CD/DVD writing software that you use was purchased separately, uninstall the software, restart, and then use its installation discs to install the software, and then restart again.
    The following procedure is an example of how to correct a No burner is currently available message in CyberLink Power2Go.
