Hi, a few months ago i bought a World Expedition ROM on e-bay and 
installed it into my command station.  It works, although I haven't 
played with every sound on it.  

Last night I was looking around at the Diagnostic Mode and for the 
first time I ran the 'Test Sound ROM' diagnostic on it.  My other ROMs 
pass the test, but the World Rom reports 'BAD BLK  4b'.   I tried re-
seating the card in a different slot and the result is the same.  
Anybody here know what's up with that?  

Thanks!
Mike
