tomcat-users.xml corruption problem

[sagin]

I have been running tomcat on windows 2003 with no problems until the computer was unexpectdly shut down (power cut).

When I restarted the computer and tried to run tomcat again it wouldn't work.

I saw the following exception in the catalina_log:

2005-12-27 17:02:30 UserDatabaseRealm[Standalone]: Exception looking up UserDatabase under key UserDatabase

After inquiring a little I discovered that the tomcat-users.xml file located at conf directory is empty.
After I replaced this file with a valid one, the problem was solved. I saw some more messages in this forum that regard this problem.
And here's my question:

I don't want to need to replace this file every time the computer crashes unexpectedly, how can I prevent this file from being corrupted?

I'm not really sure what this has to do with Tomcat - its more of a OS related problem.

You CANNOT prevent a file from being corrupted if its going to be corrupted due to unforseen circumstances.
