You are misreading the fsck manual page. Let me take you through it:
fsck - file system consistency check and interactive repair
Note what it says carefully. It says "file system". It does not
say "file consistency check and interactive repair".
If you want your files to not lose a byte, use the "sync" option.
Come on. Just do it. Give it a try. Then you will understand.
