 I had been told about a product from Highwater Designs, the address
of which I forwarded to comp.periphs.scsi (in the first referenced
article).  Mike Tuffs followed up on that, and here's his note to me.

I've just phoned Highwater designs, (they're only about 10Miles from here...),
the interface is a special for CDC SMD drives, comes as a couple of boards in a 
box, they're designs specifically for a printing application (Hell/Cromatron)
and are about UKP8000 ea ($15,000 ?)
not cheap.....

Hello world!

Our local Western Digital sales rep. here in denmark told
me today that WD has stopped selling their chips because they
want to use them themselves. Does anybody know if this is true????
I ask this group because I use the WD33C93A which is an easy to use
SCSI interface chip.

Thanx in advance.

   The full 310f, including a PC runs around 25K with all the software.
   It is pretty decent, for both analysis, conformance, and target

   Get a 386 PC with either a fast disk, or configure it to have a

   The HP module that drops into a 1650 analyzer is pretty good if

I just thought I would add a couple to the discussion:

Arium makes a $100 cable/software package to make their logic analyzer
capture and disassemble SCSI.  If you have an analyzer anyway this is
a cheap and flexible way to look at SCSI.

Pathfinder 1000 by Workstation Products is a $1000 SCSI analyzer that
is quite excellent for the price.  It is literally the size of a brick
and has LEDs for all the signals on its side.  It uses a serial port
to a terminal for display and has an 8K capture buffer.  I would
reccomend it for all but the most serious SCSI developers and even
then you might want one to have redundancy and for simple jobs.

  I recently bought a used SCSI drive and an Adaptec-1542B controller.
The drive itself apparently has no terminator, and needs a terminator
that plugs between the device and the cable. (that is, it's got a male
and a female rectangular [not Centronics] plug, and the terminating 
resistors go inbetween the two.) 
  Needless to say, the guy I bought it from did not include this vital 
organ. (the drive was in the middle of the bus, so it didn't need it.)
Locally, I've been able to find what I think would be the right thing, 
only it has two Centronics connectors, instead of the internal-style 
connectors.
  Does anyone know where I could find such a beast? Or, if it's not
too difficult, what the pin connections and resistors for it would have
to be? 
  Thanks in advance...

Can a drive > 1 GIG be formatted under DOS with the Adaptec 1542B ?

I can only get 1024 cylinders to format with the Adaptec drivers.

Storage Dimensions tells me that Speedstor with format my Elite-1
drives to the full 1.3 GIG capacity, but they are using a custom
BIOS on their 1542B controllers.  They tell me that it WILL work
without this custom BIOS, but I'd like to be sure before

After discovering one speed problem, have you considered investing in
Colorado's FC-10, or TC-15 controllers?  These dramatically speed up the backup
rates of your DJ-20. (250MB Tape drive).

The data transfer rate, I suspect, of your floppy controller is 500Kbps.  If
you use the FC-10 (High speed card) or the TC-15 (Hardware compression/High
speed interface) the data transfer rate is 1Mbps.  A nice way of increasing
your "wait" time.

I'm trying to hookup a maxtor tahiti 1bg read/write optical to a

a mac. Peripheral Land Inc. has sent me two of their Future Domain
Corp. scsi host adapter cards. I tried the first one on eight clone
pc's and the second on three clone pc's (HP, toshiba, mylex motherboard). 
In all cases, the error messages say things like "there is
an error in reading the size of the device", "the device may not
be inserted", "the size is zero", etc.

I've even change the scsi cable to no avail.  Any suggestions?
Alternatively, if anyone is successfully using this drive on a pc platform,
I would like to know the manufacturer of the scsi adapter card, and the
software, and how to order both.

Thanks.

Greetings,

   I getting ready to do a UNIX partition, format on my shinny new
Fujitsu model M2624SA 520Mb SCSI drive. However, every SCSI drive I've
ever worked with before was organized with a fixed number of sectors per
track, looking much like a sliced pie. The M2624SA has several zones,
or cylinder groups, and each zone uses a different number of sectors
per track. Specifically, the drive is organized as follows;

zone number            1          2          3          4
track numbers      0-606    607-847   848-1157  1158-1429
sectors/track         70         66         62         56

My question is; Can I use a single number for the sectors/track? If so,
does one use the max, min, or average value??? I've managed to get by in
the past with a minimal understanding of how these numbers are used by
format. Can anyone recommend a good readable reference that goes into
more detail on this??? Any pointers to reference material, or specific
suggestions would be greatly appreciated. Please reply by e-mail,
I will post a summary of responses.

Thanks in Advance,

I desire to replace my current outdated SCSI controller card with a new one.
What I would like to find out is if all 16bit SCSI cards (that can handle
large drives, and thus use translation schemes) require the use of software
drivers. I have an old ST02 which can't handle more than 1024 cylinders,
but it uses no drivers, and thus can't possibly cause bad interactions.
I've had some minor bad luck with a LANtastic network writing to a HD
controlled by a 7000 WD FAAST card. It locks the computer now and then. 
Information on the various 16bit cards available would be greatly
appreciated (there's a computer fest with reasonable prices Sunday).

Uh, the AHA-1742 adapter DMA runs at EISA C-burst DMA timing, which is
as fast as the EISA bus can run.  No card can run faster.
I might have misunderstood the comparison, but the ISA bus boards can't
do 2x DMA over anything other card either without breaking a bunch of
stuff.  Take a look at the ISA bus spec and you'll know what I mean.

    I've been reading Computer Shopper and discovered that many, many

am interested in a tape system that can back up 200megs+ without data
compression, up to 450+ with compression.  It will be used primarily for
weekly backups. 
    Does anybody have suggestions for a particular drive?  I wish to
back up HPFS partitions, under OS/2, so do any drives come with support
for other os' other than vanilla DOS?  How is Maynard stuff?  I've seen
a couple of ads where the promote the image that they support systems
from DOS to Unix and those inbetween.

The engineer could be right that a low-level format would destroy a Maxtor
LXT-200S. In this case, the drive is wrong! A low-level format is a single
command to the SCSI drive and a normal drive should not destroy itself. It
may reject the command but not overwrite special areas on the disk.

I've (low-level) reformated my Maxtor LXT-340S, which it did. I've used it
over 9 months since and it hasn't give me any problems. My LXT-213S also
works like a charm.

As far as I've understood, the Maxtors use some reserved areas on the disk,
namely a few tracks with system software (a kind of firmware) and an entire
side of a plate for alignment information. This is used for the voice coil
stepping system. As far as I know, this plate cannot be formatted by the
drive. If you erase all information from the disk using a strong external
magnet, you probably cannot use the drive anymore.
