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?) -mike
