You need to use error free floppies.

You are throwing something together. The bin.xxx files should
only have a size of 240Kb and this files are simply copied
onto DOS disks and then read under unix with mread.
The dist.fs are written onto floppies with the rawrite or rawrite3
program and they have exactly the size of a full 1.2Mb floppy.

Under DOS you see only 1213952 bytes, because DOS itself needs
some space on the floppy to maintain it's own file system on it
and to hold a potential boot block on it.
