Article ID: Q142628
The information in this article applies to:
  • Microsoft Windows NT Workstation version 3.51
  • Microsoft Windows NT Server version 3.51

SYMPTOMS

A STOP 0x00000023 FAT_FILE_SYSTEM error message occurs when a floppy disk is inserted or removed while Windows NT 3.51 is in the process of shutting down.

CAUSE

The version of Fastfat.sys distributed with Windows NT 3.51 has the potential of showing the above symptom. There is a very small window of time while Windows NT is mounting a FAT volume, such as a floppy disk, during which a request to determine whether or not it is safe to unmount the same volume may cause the above error.

WORKAROUND

Install Service Pack 5 or later for Windows NT 3.51.

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 3.51. This problem was corrected in the latest Windows NT 3.51 U.S. Service Pack. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
