EWFmgr info for EWF RAM reg

[Piotr Rezmer]

hello,

Can anybody tell me what should ewfmgr say when launched without parameters.
I want to have RAM reg mode of EWF. There are entries in registry, but
ewfmgr (run on HD) says:

The EWF volume is "\Device\HarddiskVolume3"

The EWF volume is used as storage for EWF config. But when I use registry I
don't need any partition. Is this behaviour caused that EWF RAM reg is not
correctly configured, or this message appears even in correctly configured
system.

best regards
Peter

If you want to check on the status of EWF always add the drive you wnat
information about:
ewfmgr c:

Hi Piotr. As Franz pointed out, you should use "ewfmgr c:" (substitute the
correct drive letter if it's not c to determine the current EWF status for
a particular partition. The fact that ewfmgr is pointing out an EWF volume
most likely means that an EWF partition exists on your media regardless of
your actual setup. This may have been from an earlier runtime where you
used an EWF RAM or Disk overlay, or because you may have configured your
system for RAM REG operation within the runtime, where a RAM overlay existed
before.

If "ewfmgr c:" indicates that your overlay type is "RAM (REG)", then your
overlay is configured correctly and you should be able to ignore the
presence of the EWF volume. You can also use diskpart or Disk Manager to
delete the EWF partition.

When I enter (on boot from HD) "ewfmgr c:" I receive:

I tried this component, however with no progress... On HD I get:

"Protected Volume Configuration

On CF I get:
"Failed getting protected volume configuration with error 1.
Incorrect function."

According to Slobodan readme, it means that volume on CF is not configured
for EWF.

Now it's working. It was necessary to change using regedit
HKLM\SYSTEM\CurrentControlSet\Services\EWF\Parameters\Protected\Volume0\enabled
from 0 to 1. Then after reboot ewfmgr c: displays no error.

Now I have:
"

Piotr,

It looks like you have used boot from CF and original master HDD was present at the time.
1. You must boot only from CF without HDD present.
2. EWF config partition will always override the setting that you make in registry. So you must delete it. Follow Mats description.

Piotr,

HKLM\SYSTEM\CurrentControlSet\Services\EWF\Parameters\Protected\Volume0\enabled
from 0 to 1. Then after reboot ewfmgr c: displays no error.

Actualy this is same as if you have typed "ewfmgr c: -enable".
And this did not solved your problem. You have probably tryed booting without HDD present or something like that.

The system is working now. ewfmgr says : RAM (REG), state: ENABLED. After
restart, system discards any changes that were made during last session, so
it means that EWF is working.
