"preformatted" means: 
---------------------
- Created on the PC using the HxC software.
- Can be produced directly by using the "5-1/4 inch LIF" format
  available as a "Predefined Disk Layout" in the HxC Software.
or:
- I have created mine by loading an LIF image description from an 
  XML file and writing this to the HFE file. I used this technique because I 
  needed only one sector for directory entries for the CP/M files. 
  This is not the problem, I also tried the images produced by the
  default HxC "5-1/4 inch LIF" "Predefined Disk Layout".


"formatted" means:
------------------
- Formatted on the HP-86 using its "INITIALIZE" command. 
- This command performs a raw format and then writes a volume name 
  and directory information to the first sectors.

"seek problem" means:
---------------------
When a file is to be read the system first looks into the directory in sectors 3
and following. Then it seeks to the sector where the file starts.
when trying to read or load a file which is beyond circa cylinder 27 the 
read/load fails.

Disk images:
------------
DSKA0000.hfe  CP/M disk created by using a preformatted image file on the PC
              and then using the HP-86 "COPY" command to copy all files from 
				  a real 5-1/4" disk (with CP/M system files) to the HxC image.
				  The result looks good, but cannot be read because of the 
				  "seek issue". The files that have to be LOADed start at high
				  sector numbers, so that a seek from sector 1 (directory) 
				  to the desired starting sector fails.
				  A valid LIF file.
				  
DSKA0001.hfe  just "preformatted", nothing done to the image, so
              the same as "DSKA0000.hfe", but left untouched.
				  A valid LIF file.
				  
DSKA0002.hfe  the same as "DSKA0001.hfe", but then "formatted" on the HP-86.
              Writes over all 35 cylinders, then fails with disc error when
				  the volume and directory sectors are to be written.
				  Therefore no valid LIF file.
