Re: USB boot and EWF RAM REG

Tech-Archive recommends: Fix windows errors by optimizing your registry

Sean,
I'm using TwinMos Mobile Disk M1 USB2.0 and LG USB Drive Silver both are
2.0. During transfer I read speed: near 9 Mb/sec read, and 1Mb/sec Write.
( ms recommends 9Mb/sec write!)
Both are much faster when EWF is enabled.
I plan to use PQI U350H, I'll report if it give better performance.
Regards Raffaele

Not all USB flash disks are created equal. Some have fast controllers so
do not. I am starting a list to capture this information:

If FBA is taking 2 hours, then you have a slow controller.

Konstantin,
the procedure you suggested unlocked the stick.
I also tried to reset the same key on XPE itself, but it restarts with
EWF still enabled.
I must say that the FBA phase has been done on a CompactFlash and not on
the stick itself, to speed up operation. The first, and only time I did
on the stick it took about 2 hours!!
After that I do on the CF and at the end copy all files onto the stick.
CF and stick are both FAT32 formatted.
Perhaps some disk architecture for EWF is different.
Any idea to reduce the FBA phase time? a faster stick of course, but all
I've checked are slow.
regards, Raffaele

Raffaele,

EWF RAM Reg mode works quite well for me on all USB images I created.

If you want an intermediate (dev) solution, you can open up the image's
system registry hive offline (from another OS such XP Pro) using
regedt.exe/Load Hive function. And disable EWF there by setting the
appropriate registry value to 0:
[HKLM\System\ControlSet001\Services\EWF\Parameters\Protected\Volume0],"Enabled"=dword:0.

Hello all,
I have installed XPE image ( FP 2007) on a USB stick and boot from it.
It's rather slow, but it's nice.
I have EWF RAM reg mode and if protection is enabled it boots faster
( about 1 min. for 300 mega bytes image).
I can't disable any more EWF, since command
-disable
or
-commitanddisable hangs up the computer, that stops to reply. I only
can shut off and restart.
EWF is still enabled.
Has anyone checked EWF and BOOTUSB?
regards
Raffaele
