Symptom
Third-party FireWire drives eject or fail to recognize audio CDs.
FireWire 2.7 software, included with Mac OS 9.1, includes built-in support for third-party mass storage devices such as CD-R drives. This does not, however, eliminate the need to install any third-party software included with the drive. In the absence of appropriate third-party software, Mac OS 9.1 may allow the third-party device to recognize data but not audio CDs.
Solution
Follow the installation directions included with third-party FireWire drives for any required software.
Alternatively, you may use the Macintosh computer's built-in CD-ROM, DVD-ROM, or DVD-RAM drive for audio CDs.
