Product(s): Microsoft Windows 95.x Retail Product
Version(s): 95
Operating System(s): 
Keyword(s): win95
Last Modified: 17-DEC-2000

-------------------------------------------------------------------------------
The information in this article applies to:

- 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.

RESOLUTION
==========

Contact the manufacturer of the CD-ROM drive about obtaining a firmware update
to bring the drive into compliance with the ATAPI 1.2 specification.

This issue is resolved by the following updated file(s) for Windows 95, and later
versions of these file(s):

  SCSI1HLP.VXD version 4.00.951 dated 9/5/95 19,189 bytes

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
