Okay.  Instead of mounting jffs2...
start with an erased volume.
'dd if=/dev/mtdX of=/original_data bs=32 count=1'
try 'flash_eraseall' then
'dd if=/dev/mtdX of=/erased_data bs=32 count=1'
try 'echo "jared is cool" >> /dev/mtdX'
'dd if=/dev/mtdX of=/written_data bs=32 count=1'

Now what do each *_data contain?
