Unfortunately, I couldn't reproduce this problem. Maybe the problem 
depends on some very specific geometry settings? (number of heads, 
number of sectors?).

Could you maybe send me an image which exhibits the problem (second FAT 
not updated when copying a file which falls on these clusters), or, if 
not possible, mail me a sequence of commands which produce this problem 
starting from an empty filesystem.
