EWF and file registry/files corruption help

[reginald.louis]

Hi!

We have a bunch of PC/104 computers installed for different clients
with XP embedded. I put a EWF Ram (Reg) and I still got registry
corruption (sometime all registry files disappear) or somes files
important to boot XPe get corrupted to (like c_10000.nls or
c_10006.nls). This king of problem even append 3 times for the same
client in 5 months.

Anyone have some clues how can this append? It's is possible that is
not related to windows but electrical problem? If someone ever got
though this, please let me know!

Thanks

A few questions:

1. What type of driver are you booting from?
2. Are you using NTFS or FAT?
3. Is disk cache disabled?

Make sure you've disabled defragmentation (add a registry value named
EnableAutoLayout, type DWORD, data 0 to HKLM\SOFTWARE\Microsoft\Windows
\CurrentVersion\OptimalLayout).

It may also be a hardware issue/bad batch of drives. Does this
corruption happen with more than 1 brand of drive? Does it happen
with drives purchased at different times?

Answer to questions
2. I tried both
3. Disk cache is disabled

For question 1, what do you mean by "what type of driver are you
booting from"? Do you mean the media like compact flash or HD? If so,
I tried both and different kind of compact flash.

Yes it append with different brand of compact flash (Sandiskj,
Transcend, Kingston) and recently (about a 1month) with a fresh mobile
HD from Hitachi!

Take a look at WinSystems:

They have a good line of CF cards that support XPe boot.
