When a program queries for a file name or for volume information, Windows 2000 may exhibit the following STOP errors in Fastfat.sys:
STOP - 0x00000023 FAT_FILE_SYSTEM fastfat.sys
STOP - 0x0000000A IRQL_NOT_LESS_OR_EQUAL
This behavior can occur if the program is written to query for the file name or volume information by using an Async FileObject method. Use of this method is not currently the standard practice in most programs, and the method is therefore rarely used.
To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

Microsoft has confirmed that this is a problem in Microsoft Windows 2000.
This problem was first corrected in Windows 2000 Service Pack 2.
The program queries for a file by calling the Async FileObject and for volume information by using FatCommonQueryInformation and FatCommonQueryVolumeInfo. It can complete IRPs with a STATUS_PENDING, which results in a STOP 0x00000023 or STOP 0x0000000A error in Fastfat.sys.
