A word of wisdom/superstition from someone who has just finished restoring
his hard disk (40MB) from a zillion backup floppies for the THIRD time: when
partitioning a hard disk be sure you put "2" in the "reserved" sectors field
of your mountlist for EVERY partition.

The manual that came from my hard disk manufacturer says otherwise.
Right there in the procedure for partitioning a hard disk they show an
example mountlist file with zero reserved sectors for all but the very
first partition.

Now, I haven't disassembled the AmigaDOS binary (yet), but some painful
experimentation has given me the strong feeling that checking for 'DOS\0'
at the beginning of the first sector of any partition is an important part
of AmigaDOS's file system acceptance criteria.  Anyone in the know wish
to elaborate?

While I'm at it, can non-developers get DiskEd?  I found a copy of DiskEd
on some BBS somewhere (don't know if it was legit), but it appears to be the
old version that doesn't grok hard disks.  It would have come in handy; I
had to roll my own instead.

Also, Commodore: you might consider teaching DiskDoctor to patch up the
first sector (assuming that I'm correct about this).  I can see how it
might get kind of messy but it's pretty important.

Oh yeah -- many thanks to Dave Haynie: without DiskSalv like itself would
be impossible.
