Vista hibernation disk access

NTDEV

Hi,

Does anyone know how Vista writes to the hibernation file sectors
during the hibernation? In 2000/XP, the OS loaded a separate copy of
the disk driver without any of the associated filter drivers. Is this
still the case in Vista or is the standard disk I/O stack used
(including all filter drivers)? Or is there a new way to register as a
filter for the hibernation sector I/O?

Thanks,
Shaun

This has (finally) been improved in Vista. Filter drivers can be in the
hiber path now. We do still use the dump driver and miniport.
