System Hangs with Audio CD and NEC Intersect CDR-37 Drive

 * }

Q128495

-

The information in this article applies to:


 * Microsoft Windows 95

-

SYMPTOMS
Your computer stops responding (hangs) when you try to use an audio compact disk (CD) in a NEC Intersect CDR-37 CD-ROM drive. Ejecting the CD causes the error message "Drive Not Ready" to occur. You can use the system normally once you close the error message box.

CAUSE
The NEC Intersect CDR-37 CD-ROM drive is not supported for CD Audio when you are using the Windows 95 protected-mode drivers because it does not respond correctly to CD Audio commands.

RESOLUTIONS
This drive should function correctly with audio CDs when you are using real- mode CD-ROM and MSCDEX.EXE drivers. To use real-mode drivers instead of the Windows 95 protected-mode drivers, load the CD-ROM driver in the CONFIG.SYS file, and load MSCDEX.EXE in the AUTOEXEC.BAT file following the manufacturer's instructions. Note that if these drivers were already installed when you installed Windows 95, they may still be in the CONFIG.SYS and AUTOEXEC.BAT files, but be remarked out.

If using the real-mode drivers does not resolve the problem, you may need to disable the CD-ROM drive in Device Manager. To do so, follow these steps:


 * 1) Double-click My Computer.
 * 2) Double-click Control Panel.
 * 3) Double-click the System icon.
 * 4) Click the Device Manager tab.
 * 5) Click the CD-ROM drive, then click the Properties button. Note that you may need to expand a branch of the hardware tree by double- clicking the branch or by clicking the plus sign (+) to the left of the branch before you can click the CD-ROM drive.
 * 6) Click the Original Configuration (Current) check box to remove the check mark.
 * 7) Click the OK button.
 * 8) Click OK.

NOTE: If the CD-ROM drive is on its own controller, you may also need to disable the controller. To do so, follow the steps above but choose the CD-ROM controller card in step 5.

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