The information in this article applies to:

  • Microsoft Windows 2000 Server
  • Microsoft Windows 2000 Professional

This article was previously published under Q287524

SYMPTOMS

When you mount a volume under high-stress conditions, your computer may stop responding (hang) and you may receive an error message that is similar to:
STOP: 0x0000001E (0xC0000005, 0x801725bc, 0x0000001, 0x0000030)
KMODE_EXCEPTION_NOT_HANDLED
Note that the values in the error message may vary.

The fault address (the value in the sample error message is 0x801725bc) is in the operating system kernel (Ntoskrnl.exe).

CAUSE

This error occurs because a volume parameter block (VPB) is modified without being protected by a global spinlock when you mount a volume.

MORE INFORMATION

From the Microsoft Windows 2000 Device Driver Kit (DDK):

A VPB is a structure, defined by the I/O Manager, that maps a file system's volume device object to the device or partition upon which the volume is mounted. The file system's device object is actually used to represent the volume (VPB) mounted on the actual device (physical device object). Device objects for physical disks, tapes, CD-ROMs, and RAM disks have associated VPBs.
