Latest research supports 'b*ggered' theory, there is no driver to update having tried every windows xp dodge yesterday.
I can't fit a new drive though as being internal I don't have the knowledge to remove the back and poke around. I wouldn't in a car and would definitely not with a computer.
The trouble is this accounts package refuses to save files to anything but floppies, there are still programs that require them and until they allow it to burn to CD it's that or lose the lot. Not a happy prospect...
