Microsoft Windows 95

SYMPTOMS

When you insert a particular audio CD in the CD-ROM drive, it may not be recognized and CD Player may not be started automatically, even if the Auto Insert Notification option is turned on.

If you start CD Player manually, the CD-ROM drive light may flash continuously, and you may receive the following message:


   Data or no disc loaded
   Please insert an audio compact disc.

Most other audio CDs are recognized automatically.

CAUSE

Your IDE CD-ROM drive is not fully compatible with the ATAPI 1.2 specification for IDE CD-ROM drives.

MORE INFORMATION

The following IDE CD-ROM drives are known to exhibit the behavior described in this article:


   Manufacturer           Model    Firmware revision
   -------------------------------------------------
   Panasonic/Matsushita   CR-581   Earlier than 1.04
   NEC                    273      Earlier than 4.21

This behavior occurs with a few audio CDs that are mastered in an unusual manner. Normally, track 1 begins at the 2-second mark on the disc. On the audio CDs that trigger this behavior, track 1 does not begin at the 2- second mark. When the Windows 95 CD-ROM driver attempts to locate track 1, the drive reports a status that is not expected under the ATAPI 1.2 specification. Based on the status returned from the drive, the Windows 95 CD-ROM driver tries to find track 1 continuously, never receiving the expected result code from the drive.

The following audio CDs are known to cause this behavior:


   Title            Artist   Publisher
   -----------------------------------------
   Shepherd Moons   Enya     Reprise Records
