[comp.sys.atari.st.tech] Expanding Megafile 60

swklassen@rose.uwaterloo.ca (Steven W. Klassen) (12/14/90)

Here is a summary of the info I got regarding adding another drive
to my Megafile 60.

Some have stated that it is possible to add another drive to
my current controller, it looks like it is not the sort of thing
that I would want to do.  I was hoping that it would be just a
matter of opening the case, mounting the drive and plugging in
the cable (and possibly setting a dipswitch or two).  Instead
it seems that it is more complex for a number of reasons:

1) It seems the cable for the second drive has been cut off of
   the controller, hence a new one would have to be installed.

2) One person mentioned that the Adaptec controller has been
   modified so that data can not be read from a second drive (some
   lines have been attached to ground) and these modifications
   would need to be undone.

3) A new power supply might be needed.

4) I would have to write my own software as HDX will not support
   the second drive.

My question for Atari is:  Why has this approach been taken?  I would
think that the ability to just "plug in" a second drive would be
a useful marketing tool.  Instead it looks like you have gone to
extra expense to ensure that this cannot be done.

My reaction is:  Too much work/risk for me to undertake.  I guess
I could purchase a second Megafile but perhaps I should just save
my money to buy a better machine.

It's inexpensive.

You forget that this is Atari you're talking about.  They don't 
market hard drives, or STs for that matter.  (Actually, a friend of 
mine, the one that tells me about the $400 386 systems, saw an Atari 
ST co-op ad one morning during the Today show.  Had the dealer's 
address and phone number at the end.)

Or a better hard drive.  I would think that people who read this net 
would know better.

I recommended an ICD drive to a friend of mine who knows nothing about
hard drives, and he went out and bought a Megafile 30 for $500.  He
could have had a larger drive and better host adapter and software for
that price if he would have heeded my recommendation.  It boggles my
mind when I recommend things to people after they ask me, and they go
ahead and do the opposite.

Yes. The 20-pin-connector for the second harddisk is not soldered in.

If you use a low-power-supply-harddisk, you don't need another power-supply.

For the HDX-Software this is true. But: There is a famous harddisk-driver
written by Claus Brod (unfortunately NOT PD) which supports a second drive
on one MEGAFILE-Controller.

You need to be experienced in hardware-working for that. But after all
modifications, it's running quite well ! I've modified my own MEGAFILE-30-
controller and it drives now 2 Seagate-drives without any problems. And
the system is running 24-h a day under OS-9 ! Sometimes it takes 4-5 weeks
until i must reboot my machine, so the hardware of Atari isn't bad at all !

Why not try the Third Coast drives - they do allow you to 'plug in and go' with
a second drive from what I've read...
