Is there a way to use HORM (Hibernate, Once Resume Many) with EWF
(Enhanced Write filter) on a partition which uses a pagefile, (the
pagefile resides on another unprotected partition.)
--> I'm looking for quicker bootup time, by using HORM.
Basically, HORM stores the snapshot of system memory, when the
hibernation file is created.
--> So the pagefile must match this current state of memory.
--> So if the pagefile which is on the unprotected partition
changes, and you use a state of memory when the pagefile was
different, you can have corruption problems.
Reading other's documentation talks about unmounting all drives which
are not protected by the write filter.
But, you CANNOT dismount a drive, which contains a pagefile. (Unless
there is some hidden windows function to stop the usage of the
pagefile.)
I can see a number of methods which could be used.
1. Force the pagefile to zero, and flush it so it starts with no
pagefile.
Save the hibernation file at this time.
--> I have not figured out how to set the pagefile to zero length,
without causing a reboot.
2. Somehow start with a base pagefile, which become the current
pagefile on every bootup.
So, the system starts with the hibernation file, and the matching
pagefile on every boot.
--> Maybe, using the runonce registry entry one could copy the
base pagefile, (the once which matches the hibernation file) to the
real pagefile.
3. Maybe create a system which has a starting pagefile which is zero,
but can be expanded. Then somehow don't allow the pagefile to be used,
so the hibernation file can be created with a zero length file.
--> This method will probably fail since, subsequent savings of the
hibernation file, will probably result in a pagefile which was used.
Any other ideas, or solutions would be greatly appreciated.
My system has 3 partitions where only the first partition is protected
with a RAM-REG write filter. The pagefile is located on the 3rd
partition.
I've asked this question years ago, and still have not seen any
answers.
Thanks in advance.
