DIM X% 31:Y%=X%DIV256
X%?0=0:X%!1=&FFFF7C00:X%?5=8:X%!6=lau%:X%?9=1:A%=&72:CALL &FFF1
 
where lau% is the bigendian sector address.

http://mdfs.net/Info/Comp/BBC/IDE/ADFS/Apps/WEDITOR is a simple
Winchester EDITOR. However, the OSWORD &72 interface does need the
drive to contain a valid ADFS root system before it will allow any
access to it. You can't even write a blank filesystem with OSWORD
&72 if there isn't already a filesystem there!
