Your luck may run out trying to copy it back to the original disk, though, since it's the dreaded 1,457,664 bytes in size. I remember cringing whenever I saw files that size because I often couldn't back them up on used floppies and would need to break out new disks for them. You might be able to take the original disk apart, though, and put a new internal disk into it (so that you'd preserve the shell with the sticker on it). That'd be an interesting project. Either way, good luck.
