you're right ... i'll claim that i was deceived by the lack of input checking.  
sounds like the code should be aborting if the input is too large instead of 
silently truncating.  then the memset/{0} is unnecessary:
	- write out the data read
	- lseek to the checksum position
	- write checksum
	- ftruncate to total length (16KiB?)
