[comp.sys.atari.st] hard drives

a360ad@blake.acs.washington.edu (Gnurr) (03/01/89)

I am considering buying the Seagate ST296N drive
with ICD and Adaptec 4070..... has anybody 
had any experience with this setup?

I would like to put MINIX on this drive.

Recovering from my aborted attempt at running a Seagate 296N
and Supra Host.... I am once again in the research stage of 
purchasing a hard drive for my 1040ST system.  

The following are my "requirements":

1. To succesfully run MINIX with minimal modification (don't know 
        how to modify drivers).

2. 80MB or more of memory

3. Prefer a built-in SCSI

4. 28ms or faster seek rate

5. Data transfer rate of 550 k/s or better

6. Quiet!


Anybody out there who has a drive(s) fitting the above, please
e-mail me.... or better yet... post to the net for the benefit of
others.               

Thanks!

Try a Quantum 80S - 80MB, integrated SCSI controller, 11/19ms seek time
(11 with a cache hit), 630+kb/sec transfer rate, quiet and cool. I'm using
one with Minix right now, no troubles...

Quantam's are *very* nice, they are so quiet you can barely hear
the stepper motors!  They are pricy at around $750 though, but I just
saw a post in the misc.forsale base from a guy who was selling a
few of them that were three months old for $550!  If I hadn't just
bought a couple of Seagate 157Ns they'd be mine!

I have seen quite a bit on hard drive cnfigurations for large hard drives for
the ST (Seagate 277N - 65Mb or 296N - 80Mb , or Quantum 80 Mb), but haven't
seen anyone reporting my eventual solution.  I started out by ordering one of
the new Berkeley Microsystem BMS200 boards, along with a case, power supply and
fan.  I had planned to get a Miniscribe 6128 drive (RLL controlled, 110 Mb),
then selling at about $650, so I also ordered an Adaptec 4070 controller.  The
whole package from BMS (board, controller, box, fan, cables) came to some
$300+.  As my order was one of the first individual orders to be processed for
the BMS200, and the boards were just being developed, there was a couple month
delay.  In the mean time the Miniscribe drives went down in price and then (to
my horror) went out of production (something better is coming along?).  So when
I finally received my BMS box, there was no 6128 to be had! About the same
time, Lyco Computer Co. began to advertise an RLL controlled Seagate drive (the
4144R) rated at 120 Mb for about $680.  I promptly ordered one. Because of
delays in shipping at the factory, there was another month delay before I could
get the drive, but finally when it arrived, I spent a short time figuring out
cables and hookups and got everything hooked up. Using Supra formatting
software (no one else goes beyond four 16K partitions that I know of) I
formatted the thing, and have had it running now for a couple weeks without
problems.  So the result, despite all the delay is a drive of some 115Mb
formatted space for somewhere in the neighbourhood of $1000, which seems to be
a rather good value compared to other configurations announced so far.  In
short, I recommend it (though I am still holding my breath).

Just thought I'd report a success story.

I'm in the market for a hard drive and was wondering what c.s.a.st's opinion
of the 44 Meg removables are?  Which are best based on cost, reliability, and
support?  Are the cartridges interchangeable from one to the next (specifi-
cally Atari's and that one that comes full of PD software)?  Is the one with
the PD software available without getting the drive?

Please e-mail replies.

Well, you have 4 choices.  All of them involve the Syquest SQ-555 44mb        
removable platter mech.  Three companies (that I know of) make such a beast
for the ST:  Toad Computers, Carter Enterprises, and Atari.  The fourth choice
is to roll your own.  I have a buddie that just bought a magnum Toadfile (this
is the toadfile drive w/three cartridges), and he loves it.  I would recommend
it over the Atari unit because of both price and the ICD controller in the 
Toad.  I have not heard much about the Carter entry, other than it is contained
in a small shoebox-style case.  The Toadfile has room and cables for one more 
device (but maybe only 3.5", I cannot remember).  Since it is an embedded SCSI
device, whipping one up yourself should be cake.  Just get a baby AT case with
power supply, and ICD host adaptor, and a Syquest.  You can get a Computer
Shopper and hunt down a Syquest mech (I was quoted a price of $519 about a 
month ago).  Bolt all the stuff together, and voila.  One last footnote:  I have
heard that Syquest is about to release a new mech that stores >100mb on a 
platter, and charge the same retail for it as the SQ-555.  I do not know if this
means the same price to the customer in the end though.  If someone could 
confirm/deny this, I would appreciate it.

	Re: Syquest Drives.
  I heard that Syquest announced release of a 175meg drive which would retail
for the same price as the current 44meg unit. That was at the spring Comdex.
At the same time they said they'd lower the 44meg price by $200US. I'm still
waiting......

	The SyQuest Mech is a standard 1/2 height 5 1/4" drive.
The TOADFILE has space to accomodate TWO of these 5 1/4" drives.

	NOTE:  CARTER GRAPHICS's drive also uses ICD ADV+ host, and
	       is also nice.  They make several models... including
	       an under monitor style (like TOAD) and also a SUPER
	       small drive (just a bit bigger than a floppy drive.
	       The front panel is about the same, but it is deeper.)

	NOTE:   THE $519 SyQuest comes WITHOUT A CARTRIDGE!!!!!
	-----   A cartridge is an additiona $79 plus shipping...
	        The ICD ADV + is (I believe) around $100.
	        A HD Case and Power Supply is at least $80.
	        A fan is cheap, about $10.

    CONCLUSION: After adding up all of these prices, and NOT INCLUDING
    ----------- Shipping charges, which may be substantial, we arrive
	        at the figure $788.00.  Seems like a lot of TROUBLE
	        When one considers that the TOADFILE is about $850.00,
	        and includes the larger UNDER MONITOR case which has
	        a special power supply to supply TWO (2) drives, and
	        has a case to handle 2 drives as well.


	I'm not affiliated with any of the above companies, and the
opinions expressed are my own.  I do own the TOADFILE, and a friend of
mine owns the CARTER GRAPHICS drive.  We are both very happy and
consider our drives to be entirely equal.  The only deciding factors in
purchase should be case style preferences and locality to MD or Utah
(where Toad and Carter are loacated respectively).

	I would also agree with the previous poster that the ICD
ADVANTAGE PLUS host is far superior to any other, ceartanly better than
the ATARI.  I've read on usenet that people are having troubles with the
ATARI when it comes to Swapping disks "on-the-fly" where the disks have
different partition sizes...   THERE IS ABSOLUTELY NO PROBLEM WHATSOEVER
in this type of process using ICD's ADVANTAGE... I consider this a HUGE
ADVANTAGE.... PLUS, the ICD ADV+ comes with a battery backed clock that
is a great Plus!  

	About using SyQuest disks on other SyQuest drives.  I have 2
froends with SyQuests (one Carter, one Toad).  Between us we have 7 
cartridges.  All of these carts. are COMPLETELY compatible in any of
our three drives!!!  (of course if you had the ATARI host, you'd not
be able to swap on-the-fly with these carts... because they are all
partitioned differently.... including SPECTRE partitions.)


Hope this helps,

For that matter, how about a directory of everyone's favorite companies?
or is this too much like an advert?

Need some advice.  

I currently have a 520ST and want to purchase a hard drive.  I am looking for 
recommendations on manufactures.  Is it better to mail order or buy one
locally?  What are the standard prices?

Thanks in advance.

The Doctor is in.  Please have a seat.  (Just kidding. Har har :^)

I think most people will agree that ICD is the way to go if you want 
the best.  Most third-party vendors sell ICD host adapters so you can 
put together your own drive or have them assemble it for you.  I have 
a Seagate 157N-1, a 50meg (okay 48.9meg), 28 ms drive.  I've had it 
for a year and a half, treated it well, and it's worked flawlessly.  
I have it in an ICD case.  I've heard that fans in other cases are 
kinda loud.

- Is it better to mail order or buy one locally?

If you have a good dealer nearby that has a good price, go for it.  
If this isn't the case, there are many places that will put together 
a drive usually with any size mechanism from any company.  Toad 
Computers (800-448-TOAD) is a reputable place.  So is Carter Graphics 
(801-628-6111).  I bought mine from Joppa (800-876-6040).  Joppa buys 
the host adapter and case from ICD and buy the drives from Seagate 
and assemble it for you.  Ask your dealer if he will buy the case and 
drive separately and put it together for you, or you can put it 
together yourself.  

- What are the standard prices?

A year and a half ago, I bought mine for $665.  They now have the 
same setup for $579 (September, 1990 issue of ST Informer).

Good luck.  If you have any other questions, drop me a line.

Perhaps most would agree, but I don't agree at all.  If you want the best,
get the Berkeley Microsystems BMS-200 host adapter.   Nothing else touches
it in terms of getting the signals and timing right.

ICD may be much more widely available, but that doesn't make it the best.

True, but doesn't ICD have the better driver software because of its 
caching and verifying capabilities?  I have heard that the BMS-200 is 
better than ICDs, but I think that ICD's software that is included 
which, (from what I understand) doesn't work on other host adapters.

You might be right about signals and timing. 
However, be sure to have your drive powered or disconnected whenever
you power the ST. The BMS 200 pulls down some of the ST's lines on 
the DMA interface which wil fry the DMA chip if this lasts too long.
I've found out about this the hard way & I definitely do not like it.

On the other hand: the people at BMS are very helpful if you encounter
problems. I once had a bad disk, and they gave me quite some support,
even though I'm living in Europe, so phone and mail costs are not
that cheap.

I'm interested, (I'd like to run my 296N with 1-1 interleave 8-)
but I have several questions:

Does the BMS 200 verify at all?  How long can the Acsi cable be?

How do the various third party caching programs compare to the *very*
fast ICD caching driver?  Give some sort of measurement please.

Is there some program out there truly comparable with ICD's Cleanup or
the Supra Utilities, e.g. Beckemeyer's Hard Disk Sentry??   Michtron's 
Tune Up currently does *not* cut it.

Does the BMS 200 support removeable media - especially Syquests 8-)?
I do know that Berkley Micro can supply tape drivers (and advice) 
for many of those cheap tape drives that are out there.

Has anyone tried to use the BMS 200 with Spectre GCR (especially with
a 296N or 277N on 1-1 interleave 8-), do any of those Mac SCSI add on
devices (e.g. a hand scanner) work with it?  I doubt this, but maybe
something other than a hard disk *does* work, if its driver stays away
from the Mac hardware.

Finally, does anyone know if ICD fixed up their newer adaptors to be
more like the Berkley one?

Thanks for any info,

I have a 296N, and was led to believe that it is rom-hardcoded to a 2-1 
interleave that cannot be changed without reburning something.  Is this 
in fact not true?

I read something a while ago that mentioned that the version 8 ROMs 
on the 296N will only give a good transfer rate on the ST at 2-1 
interleave, but even then, it's only around 400K/sec.  (K/sec is the 
correct measurement for transfer rate, isn't it?)  The version 7 
ROMs let you go 1-1 interleave and therefore you supposedly get a 
much higher transfer rate.  If you format at 1-1 with the version 8 
ROMs, you get an incredibly poor transfer rate, somewhere around 
40K/sec.

We have an Excabyte 8 mm tape drive (2 Gbyte). The BMS-200 we ordered
did not work with it (and it took > 3 months to arrive). The ICD
board works fine. Werner

You do not want to run a Seagate 296N at 1-1 because the disk transfer rate
is less than 90 kb/sec at that interleave.  Formatting it at 2-1 interleave
raises the transfer rate to over 430 kb/sec.  It's like using a different
disk.  I bought one when they first came on the market and formatted it
at 1-1 and was shocked to find that my 28 ms disk was sooooo slooooooooow.

Yes I do!  At home I have old postings about this.  Someone from Berkley 
Microsystems claimed that Seagate tests all 277Ns and 296Ns with a 1 to 1 
interleave, and listen to you (figuratively) slack jawed when you
complain that you can't run them that fast.   The problem, I am given to 
believe, is in the host adaptors we use, only the BMS 200 really meets SCSI
standards currently, or so I hear (yeah, I know, you could say that 
the 2XXN series is barely SCSI too 8-).  BMS *currently* advertises with a
line saying something like:  <if you have a 296N or 277N and want to 
run it with 1 to 1 interleave, call us>


> Formatting it at 2-1 interleave raises the transfer rate to over 430 kb/sec. 

(or lowers it to that if you're running a BMS 200 8-).

Deletions....

I'll dig up the posting I mentioned (thought I had it here too) if
anyone's interested.  I'll also dig up Berkley's phone and address so
you can check with them directly.

Check it out - I might be right - and wouldn't all the 2XXN owners
be happy then! 

Well, only unhappy about the DMA port overloading that occurs when 
the BMS 200 is off, that someone stated in a posting today 8-(.  
I hope that's been fixed.

I have a ST296N running full speed at 1:1 interleave on my ST.  The key is
that it's attached to a BMS 200 host adapter.  Vance from BMS explained the
problem over the phone a long time back; here's how I remember it:
   The ST296N requires that the host adapter acknowledge receipt of a data
package within a time window that's at the very low edge of what the SCSI
standard dictates.  Most host adapters at the time didn't respond quite fast
enough to satisfy the drive when it was formatted 1:1.  The BMS 200 responds
fast enough.  Perhaps other host adapters do by now, I'd have no way of 
knowing.
   Anyone from Seagate reading this?  Care to give more details?

  I think there was some discussion here last year about this, and it was found
that the latest series of Rom for the 296N had been deliberately slowed down
by Seagate so that the drives would work with Macintoshes. I guess Apple ordered
a lot of them and the Mac couldn't keep up to the original transfer speed.
  Someone tryed to get the old Roms from Seagate, but no luck.

Someone posted here saying that he runs a 296N at 1 to 1 interleave
with a BMS host adaptor and gave a short explanation of why there's a
problem.  I called ICD to see what their story was, but got an
irritat{ed _and_ ing} guy who said there's no problem, sometimes it
works with 2XXNs and sometimes it (1 to 1 formatting) doesn't.  He
hardly let me get a word in edgewise and wouldn't even *consider*
investigating, let alone making the ICD adaptor work with these drives
that barely meet the SCSI specs.  Such a pity, the ST end of ICD HAs
is superb, long cable with optional write verification (that I use)
and a great cacheing driver.  We'll get an update soon from Vance
Chin, as I am getting BMS' Host Adaptor info sent to me.

 Good luck with the BMS unit and I hope it works for you, but you will
note the person who said he had on working on a BMS didn't say how old
it was or what ROM revision. ICD's latest board has the full SCSI spec
if that is in fact the problem, and their software is excellant. It's
too bad the person on the phone was such a jerk as the people they have
doing online support on GEnie are fairly reasonable and in formative.
