Hi Eric
 I think for now, we are keeping both the H8D and the
H17 ( SVD ). We have added that for the H8D, there
can be one optional byte added. This would be to have
the volume number for non-HDOS disk. We believe that
this should be backwards compatable with most of the
code so far but allows one to state the volume number
when it is not part of the normal data. The additional
byte would be the last byte of the file so that the
H8D file would otherwise seem the same to a program
that only transfered the first 100K.
 So far, all of the non-HDOS have been volume number
zero but that could always change. I used the volume
number zero this weekend for the CP/M stuff and it worked
fine ( after I read my own instructions ).
 I forgot that one needs to run the disk boot with the
drive empty to setup the drive parameters. I even noted
in my readme that one needs to follow the steps exactly
of it wouldn't work. I proved this to my self several
times before I actually did a step by step.
