   HELP ME.....PLEASE!!!

Ok! Lets try.

|Stuff deleted here...{

   Well, first of all, my Amiga decided that my boot partition (dh0:)
   was no longer a DOS drive, so it refused to read/write it.  I recovered
   all the dh0: files with DiskSalv (thanks Dave) and backed up dh1:.
   I then formatted the entire drive with the Map option on (using SupraFormat)
   to map out the bad sectors (I know this wasn't absolutly necessary,
   but I did it anyway).  I restored dh0: with the DiskSalved floppies.
   Then, my Amiga refused to boot from the HD, instead asking for a Workbench
   disk.  It seemed to only partially use the Workbench disk because my
   startup sequence on dh0: was being executed.  Anyway, I was trying to 
   fix my boot problem by using SupraEdit.  When SupraEdit was run, it 
   would tell me:

	   Warning: Found invalid FileSysHeaderBlock structure.

Ok, this is something I have also encountered with my Supra Harddrive.
The problem is (I suppose) that you have also formatted whole
bootpartition info. You can write it again with a program called 
SupraInstall (or something like that) and it can be found from
original Supra-bootdisks!

   I tried coping dh0: to dh1: and changing dh1: to my boot partition, but
   it still wouldn't boot from the HD.  I played with SupraEdit some more,
   changed my boot partition back to dh0: but nothing seemed to work.

Yes, it won`t help.

   ok, the real problem:
   The last time I ran SupraEdit I got the following messages:

	   Warning: Found invalid FileSysHeaderBlock structure.

	   Warning: Found invalid LoadSegBlock structure.

Yes, looks very familiar from my experience.

   And now, when I try to boot the system I get a GURU!!!! I can't even
   boot from floppy!  The GURU number is #81000005.000007D8.  WHAT'S
   GOING ON???? 

This is certainly something, I haven`t seen. I dunno anything about
this! Sorry!
