[net.micro] M10

Well, the M10 that I used to use cost me endless hassle, lost and
corrupted data, and was generally a total disaster.  I tried to
get help from other (former) M10 users locally, but they all
just laughed and told me to get another disk -- that they had given
up long ago on their units after many fruitless conversations with
and returns to Morrow.  Morrow has gone through a number of controller
designs, several of which (at least) violated reasonable TTL design
specs in regards to S-100 loading and timing constraints.  I was
amazed that they worked at all -- ever.  It appears that the main
problem is that the units tended to operate near a failure threshold
most of the time.  If the temperature changed suddenly, or some
parameter in the disk drive itself shifted slightly over time, the
"marginal" design of the controller really started to show through.

A local friend recently purchased a brand new Morrow M16 unit (with
a more advanced controller than the older M10's had) and has
finally given up on it completely -- this after already returning
it once to Morrow.

I might add that Morrow's driver software (at least the ones I've seen)
for their hard disks are rather poorly written.  Their "install" program
is a joke -- especially since it has bugs and they have claimed
in the past that they wouldn't let me see the source since
"we lost it when the guy who wrote it left".

All in all, it doesn't take too many bad experiences to learn to avoid
certain companies.  On the other hand, the "Konan" 5 1/4" Winchester
that I'm currently using has performed flawlessly since day one,
hasn't lost a single block of data, and is much smaller and less
electricity consuming than the bulky M10.

If your M10 is working fine, then more power to you, but all
I can say is, "good luck in the long run..."
