Windows NT Does Not Detect Media Change on ATAPI PD CD-ROM Drive

ID: Q226369

The information in this article applies to:

Microsoft Windows NT Workstation version 4.0
Microsoft Windows NT Server version 4.0

SYMPTOMS

Microsoft Windows NT does not detect a change in media when a FAT-formatted PD is removed from the drive. Even if another disk is inserted, both Windows NT Explorer and the DIR command will continue to display the list of files from the first FAT-formatted disk.

If the first PD disk present is formatted with the NTFS file system, Windows NT will correctly detect the change in media when the first disk is removed. Only FAT-formatted media display this problem.

After the FAT-formatted media has been inserted and replaced, the only way Windows NT can display the correct media contents is if the media is reformatted or the system is restarted.

CAUSE

This problem occurs because the Atapi.sys driver, which is responsible for this device, does not handle media change detection on this hardware correctly.
