The guy was having trouble getting his Floppies working.
So, if he needs to format it to get it to work, then he needs
to format it.   Regardless of how you read the text.  He seemed
to be wasting more time trying to write floppies with defects
than he would have by running the format.

It formats out to 1,457,644 bytes.   That is what he needs.
He was seeing less than that, until later.  I don't think
his response went to the list, though.
