Recommended way to format disk from assembly?

[Egan Ford <datajerk@gmail.com>]

Hello all,

I am trying to create a dumb-down one-way version of ADT, but I am
getting strange (but consistent) results.  If I create a diskette from
an image (computer -> //e disk), and then use ADT to read that
diskette to create a new image (//e disk -> computer), the images are
identical, yet my diskette will not boot.  If I use ADT to create an
image, then it does boot.  Both the booting disk and the non-booting
disk when ripped by ADT have the same md5sums (I also did a bit for
bit check).

Stumped.

I am using RWTS to format as well as write out the data.  My guess is
that the format is somehow not correctly skewing the disk.  Dunno.
Ideas?

Thanks.
