EWF partition on second disk?

[Mike]

Hi,

I use EWF and create EWF partition on second disk,
it works fine,
but when I change the second disk, the EWF partition can't use, the EWF
disabled.

How to enable EWF? I won't deploy again.

Thanks!

Mike,

First do you need disk overlay, or you can use RAM overlay.

Just to make sure that I understand.
What do you mean by second disk?

You have two disks in your device.
Run FBA on one then copy post FBA results on other?
Or you remove first disk?
How do you choose from what disk to boot?

How did you deploy your image in the first place, and where?

Please clarify this so we can help you.

Regards,
Slobodan

I have two disk in my device,
the disk #1 has only one partition, the disk #2 has unpartitioned space.
So I copy Run-Time Image to disk #1 and run FBA, it create EWF partition on
disk #2.
The problem is when I use disk #3 to replace disk #2, the EWF can't work.
I know the disk #3 has unpartitioned space but no EWF partition, please tell
me how create EWF partition on disk #3.

Mike,

rundll32 ewfdll.dll, ConfigureEwf Start

Undocumented, and may not work so use at your own risk.

The original question isn't clear, but it sounds like it could be the same
problem I had some time ago: EWF stops working after cloning disks.
There are two solutions: use another method to clone the disks (byte per
byte copy instead of ghost's fast and friendly way), or else clone before
FBA. Both mean device preparation will take several times longer.


In my case, ewfdll must have said to itself "I see no protected volumes, so
this EWF partition isn't necessary".

Before I ran it there was a valid EWF partition, but ewfmgr reported 0% in
use and found no EWF-enabled volumes.

After running it there were still no EWF-enabled volumes, and there no
longer was an EWF partition either.

Mike:

To re-create the EWF partition you can try this reg hack. Under
HKLM\CurrentControlSet\Control\WindowsEmbedded\FBA find the key that
contains the EWF creation info, i.e. where the EWF data store is created.
The value DllEntryPoint will be ConfigureEWF in the Parameters subkey.
Change FBAWasHere from 1 to 0 and reboot. This will tell fba to re-create
the EWF partition hopefully on your disk #3 the next time you boot.

From my experience, this doesn't always work which is why I now use Ghost to
deploy the EWF partition.

Thanks for your replies!

I have tried to use your methods, but it cannot work.
It is difficult to clone disk by using Norton Ghost for my customers,so I
need a better way to re-create the EWF partition.
