With all due sympathy for Rick's problem, the fragility of the Amiga file
system is one of the primary reasons I didn't bother renewing my "Developer"
status last year and stopped developing commercial software for the Amiga.
[The advent of SVR4 on the Amiga will, of course, change my opinion. :-) ]

I hope, for everyone's sake, the problems have been fixed in 2.*

Nowadays, I develop new software on UNIX where it's "safe" to do so, and I
port the occasional program over to my Amigas.  If you think Rick has a
problem with 92MB, mine would be over 10 times more severe if I had that kind
of trouble occur to my HD during development; definitely NOT worth the hassle
for something that shouldn't be occurring in the first place.

Without a doubt, the things that are needed for the Amiga (and from CBM as
officially supported tools) include:

	1. equivalent to UNIX's "fsck"
	2. equivalent to UNIX's "fsdb"
	3. easy and convenient (ideally automatic) bad-block mapping while
	   online (SCSI *can* do this automatically in case you were unaware)
	4. SCSI tools along the lines of those found at "adaptex" by Roy Neese
	   (of Adaptec) for the MS-DOS world ... these tools are simply
	   incredible.  If you want to grab them, I've included an extract
	   from my /usr/lib/uucp/Systems for you to uucp them yourself.
