Maybe that could be it!

I've tried inspect the CF card after writing the image with fdisk, and 
it reports different problems.

Something about differences between logical and physical sectors on the 
CF card and some issue with the partition in BSD mode (fdisk on a ubuntu 
linux distribution).

BUT I'm doing this from a laptop using an external cardwriter (HP 
printer with internal writer). So I have to the best of my nowledge no 
option of specifying  geometry  of  CF card in my bios.

Regarding geometry:
1. how do I find out what the CF cards geometry is?
2. what "system" is it that has to now this geomery? My computer - so it 
writes the CF card correctly?
3. has anybody used external flashcard writers to write the cards on a 
linux based system? And which? Maybe it's the "writer" that causes the 
problem...


- and an off topic note: it's fantastic how people help each other out - 
thanx!
