did you double click the image file? if so you likely ruined it, disc
copy will mount the image read-write then MacOS will probably see the
`macos' on it is fake and remove the boot blocks. =20
here is a howto on making a boot floppy from image in macos i wrote

Thanks, Ethan. That solved the problem with the weird disk size. Now
I notice that the version of miBoot in the BootX distribution _does_
have the right MacOS type and creator, and it looks as though this got
broken when putting it into Debian. (That is, the mkboot.sh file in
powerpc-specials/miBoot would be improved with conditional code to fix
the type and creator in case we are on pmac.) It now does seem that
the boot blocks are not a big deal here, as my new floppy seems to be
acting the same as the one I made before by just copying the files.
