SYMPTOMS
After you apply Windows NT Service Pack 3 (SP3) or earlier, the NEC CDR 1800a / 1224 CD-ROM drive no longer plays audio CDs. All other functionality of a CD-ROM appears to be normal; files can be accessed and programs executed from the CD-ROM drive.



CAUSE
This behavior occurs because the NEC CDR 1800a / 1224 CD-ROM drive is not fully compatible with the Cdaudio.sys file installed by Windows NT and the Windows NT service packs. It passed HCL testing with the provision that the Cdaudio.sys file that is available from the Microsoft HCL site replace the one from the source files.



RESOLUTION
The updated driver is available as a downloadable file from the following Web site:

http://www.microsoft.com/whdc/whql/default.mspx

Create a search with the category "Storage/CD-ROM Drive" and company "NEC." Find the disk icon and click it to download the drivers. Replace the Cdaudio.sys file on the computer with the one from the Web site.



MORE INFORMATION
The NEC CDR 1800a / 1224 are produced by NEC Corp., a vendor independent of Microsoft; we make no warranty, implied or otherwise, regarding these products' performance or reliability.
