 To answer your question a true DSDD 3 1/2" drive can't read a DSHD,
 because the media is differenent... so it can't read a disk formated in a
 DSHD 
  my question was could  a DSHD disk formated using 720k parameters on a
DSDD
 drive be readable on a DSDD drive was the question... i know a DSDD disk is
 readaple and formatable on a DSHD drive it just that a DSHD drive can't be
 fooled to write a usuable DSDD disk by covering the whole or any other
 message... because the media on the DSHD disk is different.. 
I covered the hole of a preformatted 1.44mb DSHD diskette and put it
into
my Windows 2000 PC and tried to read it. It stated that the diskette was
not formatted, do I want to format it? Yes, I stated as a 720kb DSDD
diskette. It reformatted the diskette and showed the space at 720kb less
some overhead.
So on my system I could convert a 1.44mb floppy into a 720kb floppy
simply by covering the hole.
Do you need a boot disk (software) or do you need simply a formatted
720kb diskette?
