automatic commitanddisable on shutdown with RAM-based EWF overlay

[Guest]

hi everyone,

we are using a RAM-based EWF overlay on our system partition, and sometimes
need to write to disk during startup. To do this, we use the ewfmgr c:
-commitanddisable command before shutdown. Of course, getting the
commitanddisble done automatically before each shutdown would make things in
embedded-world a lot easier for us ;-)

Is there a way, maybe registry key, for doing this automatically?

Thanks for any help!

Hi Martin,

RAM EWF does not work that way.
You can call commit or commitanddisable at any time during the run time of XPe and this will only set one flag that tell EWF driver
that on graceful shutdown he should write data to disk.

So you can use run request of Windows XP/XPe to execute ewfmgr with C: -commit and if you shutdown device gracefully at some point
all data will be saved if not they will be lost.
If you want to cancel this operation from happening you can use ewfmgr to remove this flag.

Anyhow only disk EWF can store or delete data on system boot. RAM EWF can only save data on system shutdown.

Best regards,
Slobodan
