I've gotten EWF to work before (in SP1 and original XPE). My previous
method, basically the same as what other topics cover, worked fine. Now,
using SP2, it does not work. My first pass I did nothing aside from adding a
few components we needed and Upgrading the entire config - all using a
previous .SLX that ran EWF just fine.

I've got the PnP component, I've set up the EWF components as described in
the new improved help files (0 Kbytes size, don't start enabled, disable
DLL/COM Registration, etc). I've got only a single partition on the target
drive I'm building on. I have tried various timings and methods for adding
the registry settings required, and variants on the same.

In other words, I THOUGHT I had everything correct. However, I get the
'Failed to find EWF Volume' and 'Failed getting protected volume
configuration with error 1. Incorrect function.' error messages when I try
EWFMGR and EWFMGR C:.

This note in the Help file Troubleshooting section caught my attention, but
I'm not sure what it is I can DO about it. I'm not certain it applies to RAM
EWF type anyway. There are no specific drivers for my Disk Drive type - do I
need to MAKE a component for this?

"Verify that you are using a specific disk driver in your run-time image,
and not a generic disk driver. If you use EWF with a generic disk driver, the
EWF volume may not always be created."

Besides that, the drive I'm making this work on isn't going to be the final
device used. I'm creating the image on a Hard Drive then moving to Compact
Flash afterwards.

Much gratitude for any assistance that might be rendered, O Community.

Hi Kilarny,

Make sure that you have "EWF" value mentioned under
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{71A27CDD-812A-11D0-BEC7-08002BE2092F}.\Upperfilters
Use regedit fro that purpose.

Yep, got that one too. I was not clear on whether the 'volsnap' entry, if
found, should be a separate String value or should be concatenated with the
'EWF' - in other words should that be 'volsnap EWF' or:
volsnap
EWF

Thanks for the quick reply...

Kilarny,

This represent two separate filter drivers so you should add them as separate lines.

volsnap
EWF

Do you have it?

Nope, didn't have them separate. Now, I guess I need to have FBA run again
with the proper entries there?

Hi Kilarny,

Kilarny · Guest

Running with the corrected volsnap EWF entries (on separate lines) didn't
help. I still get the same error state.

I did previously check the FBALOG.TXT and there was no EWF configuration at
all. The FBA is not even trying to look up the EWF configuration. I did a
build with 'Start EWF Enabled' checked just to see if that would happen.
There were no EWF messages in the log, very strange.

I'm probably missing something REALLY obvious, but it has yet to slap me in
the face like a dead fish.

Hi Kilarny,

If you don't have anything in the FBA log then it might be that you have used reg ram ewf aproach and then tried to switch to disk
overlay, if so then you should remove EWF component and add it again to image so that call that tell FBA to initialize EWF is
executed .

Doesn't seem to be that either. I readded the component, dependancy checked,
ran it - no dice. *ponders*

Thanks for the help. Slobodan...I'll look into that, try from scratch, etc.
I appreciate the assistance, I may beg for more help on Monday. I'll review
my .SLX again and see if I overlooked something.

I have EXACTLY the same problems and symptoms as Kilarny. I have configured
my ssystem the same and I too do not have anything relating to EWF in my FBA
log. This is my brand new build with SP2 and I have only ever tried REG RAM
EWF.

So I would be very interested in any more hints or news!

Regards,
Nigel.

Nigel,

For Reg RAM EWF it is normal that you do not see log in fba.log file sice you have disabled it as par of process to make it work.
It apears that EWF problems begin to sound as an epidemy outbreak again :-(

Ah yes that is true of course.

The thing that worries me is that in the Microsoft notes it says it MAY not
work if using a generic disk driver. Well I'm just using the default driver
which I guess is the generic one. Do you think this may have a bearing on
the problem? If so, where can I get an alternative driver? I find it a bit
weird, especially as I made it work with SP1 - using with your component.

Regards,
Nigel.

Hi Nigel,

There is only one disk.sys driver and it is provided by MS for all disk types.

Hi Slobodan,

I don't know where to look to proceed with this problem. When I check the
registry it shows exactly what should be there according to the Microsoft
documentation, i.e:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ewf
Name: ErrorControl
Type: REG_DWORD
Value: 0x00000001 (1)
Name: Group
Type: REG_SZ
Value: System Bus Extender
Name: Start
Type: REG_DWORD
Value: 0x00000000 (0)
Name: Type
Type: REG_DWORD
Value: 0x00000001 (1)

The other stuff I had already set up in TD is also as per Microsoft
instructions:

Key Name:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ewf\Parameters\Protected\Volume0
Name: Type
Type: REG_DWORD
Value: 0x00000001 (1)
Name: ArcName
Type: REG_SZ
Value: multi(0)disk(0)rdisk(0)partition(1)

Key Name:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{71A27CDD-812A-11D0-BEC7-08002BE2092F}.
Name: UpperFilters
Type: REG_MULTI_SZ
Value: EWF

I didn't have a volsnap entry so just added the EWF one.

Do you have EWF RAM REG on SP2 running yourself? If so are there any
differences to how you're doing it?

Regards,
Nigel.

Hi Nigel,

I have not tried it on final SP2 version, but it worked in Tech Preview.
