Cannot Access NEC CDR-82 CD-ROM Drive

ID: Q136972

The information in this article applies to:

Microsoft Windows 95

SYMPTOMS

When you are using real-mode drivers for a NEC CDR-82 CD-ROM drive, you may receive the following error message when you try to access the CD-ROM drive from an MS-DOS prompt within Windows 95 if the real-mode drivers are not loaded into upper memory:

CDR103: CDROM not High Sierra or ISO-9660 format reading from drive <x>:

If you try to access the CD-ROM drive from Windows Explorer or My Computer, the drive appears, but you cannot see any files on the drive.

Note that this problem does not occur if you boot your computer to a command prompt and then access the drive.

RESOLUTION

To work around this problem, modify the appropriate lines in the Config.sys and Autoexec.bat files so that the real-mode CD-ROM driver and Mscdex.exe are loaded into upper memory. For information about how to do so, consult the CD-ROM drive's documentation, or contact the manufacturer.

STATUS

Microsoft is researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
