A file write operation from a device driver that is loaded prior to
Autochk.exe causes Chkdisk.exe to execute. This occurs even though the last
shutdown was clean.
CAUSE
The Autochk.exe utility, which performs the sanity check on a file system
when the system loads, runs at the end of Phase 5 of the system load
process. Any file write operation by a device driver that loads prior to
the Chkdisk.exe causes the dirty bit to set in the volume control block of
the drive. When Autochk.exe runs and finds the volume dirty (that is, the
dirty bit set in the volume control block) it starts Chkdisk.exe,
regardless of whether or not the last shutdown was clean.
This is by design.
RESOLUTION
Do not perform file IO from driver initialization routine of any drivers
that is loaded prior to SERVICE_AUTO_START (Start=2).
