Truncate

Hi. I got a corrupt database (I’m running a service to get a realtime backup from a dodgy server at one of our customers, so it’s faulty hardware that’s the problem).

I need to drop the last chunk. As fa as I’ve understood I should just be able to set truncate.chk to the last position I wan’t keep? How can I determine the last valid position when I can’t start the database?
