It's not a server or a hardware problem because I tested my data.fs on another hardware,machine. As well as it's not a another file in zope, because I tested that data.fs on zope linux, and zope windows. So it's really inside data.fs

The data file is definiately corrupted. That's what the error tracsbeack says. It's a "FileStorage.CorruptedTransactionError". The question is how the file got that way.

Johnathan, A few days ago R. David Murray posted this to you:

This may not be of any help, but I got this kind of error when I was trying to build a Zope site on a computer that had one of the bad Intel motherboards. I banged my head agaist the wall hard before I finally figured out that it was a hardware problem...

Have you verified that you're not running into the same problem (or same sort of problem)? Its easy enough to fix a corrupted database, but it will do you no good if you actually have a hardware problem because it will just happen again eventually.
