Hi

There was an question on the list earlier answered about the filename of the database.
I suspect the reason for the question was about whether the extension is gdb or not.
gdb is "protected" by system restore / windows file protection facilities, which might interfere.

Sadly, I have seen no answer so far.

Best regards,
Steffen

If I were you I would try to recreate the problem. This is an issue I
have to deal with a lot and I have never seen this. Even with the
Windows disk caching on and yanking the battery from the machine
immediately after commit, I have never seen data lost. That's not to
say it couldn't happen but with the length of time you're talking about
and multiple commits, something seems suspicious here.

It could be specific to the exact tablet or configuration you are using
or it could be a non-obvious problem in your code. I don't rely on just
looking at my code to determine if it's correct. I would get one of
these machines to test and then bash it around. Collect some data then
pull the battery and see if you get any loss and under what
circumstances. Then try the same on another machine (or in a VM). Did
you do this before deploying your application?
