Thanks everyone for all of the suggestions. What is the correct way to
postpone accessing the filesystem? If I just poll on the ZwCreateFile()
call, this seems to block the system from ever fully booting. Is there a way
to be notified through a callback when the filesystem is accessible?

Is it possible to access files on a FAT32 parition during boot time from
a
PnP driver? ZwCreateFile() is returning STATUS_UNRECOGNIZED_VOLUME. I
tried
playing around with dependencies and load order, but that didn't seem to
do
anything. If I re-start the driver after the system has fully booted, I
am
able to open the file.

During boot, only the system disk is available immediately,
other disks come later.
Due to boot optimization, your driver may start early
and the load order does not control this completely.
Try to be more flexible. If your driver can wait, delay
whatever it does, until that disk becomes available.
