Hi Lothar Belle - Not quite what you asked, but may be of interest for your  
  
problem.  (I'm assuming you have an NT-based OS such as Win2k or XP.)  
  
Get Erunt here for all NT-based computers including XP:  
  
http://www.larshederer.homepage.t-online.de/erunt/  I've set it up to take a  
  
scheduled backup each night at 12:01AM on a weekly round-robin basis, and a  
  
Monthly on the 1st of each month.  See here for how to set that up:  
  
http://www.larshederer.homepage.t-online.de/erunt/erunt.txt, and for some  
  
useful information about this subject  
  
The following tutorials are useful:  
  
Installing & Using ERUNT  
  
http://www.silentrunners.org/sr_eruntuse.html  
  
To see an illustrated registry restore procedure  
  
http://www.silentrunners.org/sr_erdntuse.html  
  
This program is one of the best things around - saved my butt on many  
  
occasions, and will also run very nicely from a DOS prompt (in case you've  
  
done something that won't let you boot any more and need to revert to a  
  
previous Registry) IF you're FAT32 OR have a DOS startup disk with NTFS  
  
write drivers in an NTFS system.  (There is also a way using the Recovery  
  
Console to get back to being "bootable" even without separate DOS write NTFS  
  
drivers, after which you can do a normal ERDNT restore.  See erunt.txt for  
  
detailed instructions.  Basically, if you make your backup into a folder  
  
inside your Windows or Winnt folder, you can restore at a Recovery Console  
  
boot by copying the files from that ERDNT folder into the system32\config  
  
folder.  After a good boot, then do another normal ERDNT restore to restore  
  
the user hives also.)  (BTW, it also includes a Registry defragger program).  
  
Free, and very, very highly recommended.  
  
FYI, quoting from the above document:  
  
Note: The "Export registry" function in Regedit is USELESS (!) to make a  
  
complete backup of the registry. Neither does it export the whole registry  
  
(for example, no information from the "SECURITY" hive is saved), nor can the  
  
exported file be used later to replace the current registry with the old  
  
one. Instead, if you re-import the file, it is merged with the current  
  
registry, leaving you with an absolute mess of old and new registry keys.

Hi,  
  
we have sometimes a broken system-file.  
  
I think this happens during shutdown prozess.  
  
With ntbackup i can make a copy of the registry files with the emergency  
  
option into %windir%\repair  
  
Unfortunatly  there i didnt find any commandline parameters to make a  
  
Batchfile which make this backup every day.

The article 281672 is in English for me. It means the write cache may not  
  
always be flushed to disk at shutdown hence some pending registry writes may  
  
not take place leaving the registry corrupted.

I am not exactly sure what you want to accomplish. So what I say below  
  
may not apply. In any event, you can capture the command line as  
  
follows.  
  
Use the NTBACKUP Scheduler to create a schedule with the desired  
  
effect. Go to Control Panel -> Scheduled Tasks and retrieve the  
  
command line from which you should be able to make a batch file.

Please explain in English why it is important to disable the Write

Maybe that's what is causing the disk corruption problem I am

Yes, I managed to get that much out of it.  
  
What I am looking for are comments that Microsoft's lawyers would not  
  
let the developers put in, like why is it there if it doesn't work  
  
reliably.  
  
The most important question to me is what happens if I turn it off. It

A source and ID may help.  
  
I will catch up on that thread when I get a couple of days off next weekend.

Strange I have been running with this cache on all these many years,  
  
and now I need to turn it off.  
  
BTW, I thought the problem mentioned in those MS articles was fixed  
  
for Win2K with SP3. I am running SP4 so presumably I do not have any  
  
problem.

It puts an entry in Event Viewer every time I reboot. It says that the

They are all chronicled in the thread on this forum entitled  
  
"Repairing Usn Journal"  
  
Something is corrupting my volume and based on the description in  
  
those articles, it could be the write cache. It all began when I  
  
commissioned three new WD drives. I also commissioned some other  
  
things which masked the problem. Now I have no other things and the  
  
problem persists.  
  
The corruption is apparently a random event since I cannot correlate  
  
it with anything. I thought it was caused by Norton Protect but I have  
  
removed all that and it still persists. I now have the write cache  
  
disabled, so I will find out soon enough.

It's a transaction log component. More on this later.

I appreciate your looking at this. All sorts of weird things are

In the meantime I may do an IPU to clean things up.
