problem saving matlab workspace

I'm using matlab7.0.
The code tries to learn a particular game.
So the game is played several thousand times.
So it would take hours/days to complete the simulation.
Becuase of the regular power cuts i usually resort to
saving the work space at the end of each game using
save('filename').

Intilaly i did not face any problems with this.even though
the number of games played were as large as 10,000. But
ocassionally i had an error saying that unable to save in
the specified file. But it used to work if i either
restarted the game or changed the filename.

But now the error is now more persistent. Almost every
time the same error pops up and this usally happens around
the 1200th game or 3000th game.Can someone help me out
with this problem.

I'm not sure what is causing your error, however you could
try wrapping the SAVE command in a try/catch and repeating
until the save is successful.

errorOccurred = true;
while errorOccurred
  try
    errorOccurred = false;
    save(...)
  catch
    errorOccurred = true;
    % Maybe put a pause or drawnow
    % or even changing the filename here
  end
end

Also, within the CATCH, you might want to verify (using the
LASTERROR command) that the error that occurred is actually
the one you want to ignore.
