Incorrect Number of Drives Appear for Pioneer DRM-600

• Microsoft Windows NT operating system version 3.1
• Microsoft Windows NT Advanced Server version 3.1
• Microsoft Windows NT Workstation version 3.5
• Microsoft Windows NT Server version 3.5

SYMPTOMS

When you use a Pioneer DRM-600 Multi-CD player that holds 6 compact discs (CDs) in Windows NT, 8 CD-ROM drives appear in File Manager.

CAUSE

This problem occurs due to older firmware versions of the Pioneer DRM-600 Multi-CD player not returning a status byte of 7Fh for device 6 and 7h. When Windows NT queries the SCSI chain looking for valid devices, it examines the status byte returned from each SCSI device it addresses. If the device returns a status byte of 7Fh, Windows NT considers it as an invalid device and does not create a Registry entry for it.

RESOLUTION

To correct this problem, call Pioneer Technical Support at (800) 872-4159 to obtain the latest firmware revision for the Pioneer DRM-600 Multi-CD player. Pioneer Technical Support recommends that you upgrade the firmware to at least Revision 804. Revision 806 is the latest firmware revision and order number is Pioneer P/N DRM-600UPG.
