After posting a request for info on Hard Disks that would
fit the 3 1/2" drive bay, I received quite a few requests for a
summary. Since it seems to be a topic of some interest, I am
here posting the data I received. My choice, based on this, was
to get the Pacific Peripherals Overdrive controller and a Seagate
ST157N drive (48Meg). My total price was ~$750. Since I used
University discounts on the drive, it might cost more to do it
yourself.
Hope you find this info helpful!

I'm sure there are plenty of choices out there. I personally have the
following configuration:
Pacific Peripherals Overdrive controller (SCSI) DMA; etc.
ST157N Drive (Seagate 3-1/2" 48 Meg drive)
The drive fits just fine on the card itself; leaving the second 3-1/2"
bay free for a second floppy drive (which I have). Or if you want it
can of course be mounted in the 3-1/2" slot.
Probably for a lab environment you want as large a drive as you can get
so you may want to look for something larger than a 48Meg drive;
I'm afraid I don't have any information on larger drives though.
I'd estimate your costs total for such extras to be:
< $1000 For controller & 48 Meg drive
Definitely cheaper if you go mail-order or you can get a discount
(is your lab at a educational institution?).
Hope this gives you something to work with,

P.S: The 48Meg figure above *does* refer to the formatted capacity.
I've seen some specs giving nice big numbers but found that they
sometimes were referring to the unformatted capacity (groan).

Try any of the Conner drives, the ST157N from seagate, the rodime 3057S and
3085S are also real nivce (and FAST). Also, there are some nice Fugi 40 meg
st506 and scsi drives.

I just went through similiar considerations - a 30+ meg drive without
using up the 5 1/4 slot on the b2000. After a lot of fumbling around,
I ordered a 40meg hardcard made by Great Valley Periphials from Go Amiga.
That card was not advertised yet and Go Amigo didn't know about it, but
Great Valley shipped it to them to ship to me, and it is supposed to be
on the way. So, I cannot tell you how it works yet -I have not seen it.
This uses a 43meg SCSI drive, and it is mounted on the controller card
so that it only takes up one card slot - but it has to go in the one next
to the CPU. (The card with space for 1meg expansion ram has been advertised
for about 2 months - with the drive mounted, there is no room for expansion
ram on the card.) The whole thing cost $825 through Go Amigo.
One of my other considersations was that I wanted a controller with the
socket for autobooting when 1.3 becomes available. ("In June", by last
report.)
If you are interested, I suppose the prudent thing to do would be to wait
until I actually receive my order (sometime next week) and check that
I still think it is a good idea.

Call Sunnyvale memories at (800)-262-3475 or (800)-922-3475 (CA)
They have 3 1/4 Miniscribe hard disks that will fit on the top left
A2000 slot. $255 for 22M and $275 from 32M RLL. The first one should
work with the A2090. The second one will work with the Adaptec 4070
SCSI->MFM controller (and the A2090 or other SCSI controller).

I'm using a Rodime 652 20MB SCSI with a Pacific Peripherals Overdrive
card in my BusExpander. I've only had it a couple of weeks, but it seems
to be very nice, and it was only $225. Got it from J.B. Technologies
in Chatsworth, CA. They advertise in Computer Shopper, but if you
don't have a copy of that their number is (818) 709-6400. They had
real good prices on other drives as well. If you call them ask for John
and mention Bill's Boards recommended them, it probably won't get you a better
price, but they seem to be a good outfit and I'd like them to know
we think so. By the way the Overdrive card is working very nicely as well.
It is a SCSI/DMA controller, and will auto-boot ( with changed proms )
when 1.3 comes out. The people at Pacific Peripherals are very responsive
and were kind enough to let us have a card for evaluation in the BusExpander.
That doesn't mean they gave us a freebie, but we can return it after the
evaluation instead of paying for it, although I think we will buy it.

All this talk of hard drives has started me thinking (a dangerous mode :).
I bought an A500 in feburary, and I'm already thinking of a 20Meg hard
drive. I know about the limitations on power, and the unexpandability (via
an internal card) without going to an expansion box.
What have you in net-land done to connect hard-drives to your A500? I prefer
the "open the box and get it running" instead of the "just connect this
wire to this pin and ... " type of system. I would like prices, and
experiences with service (manufacturer and distributers) if you can.
As a side note, I saw that Matt Dillon was tooking at a 230Meg drive. What
size of drive are other people using? What speeds?
If there is a reasonable response, I'll post the results to the net. If there
is no reasonable response I'll just have to post something else :) :)
Thanks in advance.

ps: My machine is going down for a week, in a week. If I don't respond that
I received your input, then try again after July 10. Thanks.

>As a side note, I saw that Matt Dillon was tooking at a 230Meg drive. What >size of drive are other people using? What speeds? Most people get drives in the 20-80MB range, it depends on your needs. Me? I need all the storage I can get. I've got too many currently- in-use floppies to fit on a 40, and I know from experience that (for me) an 80 wouldn't last the year. For most 'standard' users, 20-40MB is fine. If you are doing anything series, 80MB will hold you. If you are one of the few (me, Bryce though he might not know it, Peter by definition, MWM by virtue, etc...) then 80MB might be good only for auxillary storage. -Matt

Are you planning to get a tape or 10meg floppy setup with your hard drive? Or will you deplete the world's supply of floppy disks? :-) More than likely, you'll just write "DCrash" to prevent any loss of data at all.... :-) -- Dan Barrett ins_adjb@jhunix.UUCP barrett@cs.jhu.edu
