Uh, the 1740 external connector is not a 25 pin connector.  It is a 50
pin connector.  It is the new connector specified in the SCSI-2
specification.
You might try Amphenol Interconnect in Endicott, New York for cables.
They have very high quality cables and do offer the news connector
style.

Can some one point me to documentation that explains all the terminology
associated with SCSI?  Terms that fly around in this newsgroup that
I'm not sure I understand include:

	SCSI-1
	SCSI-2
	FAST SCSI
	single-ended
	differential

I'm particularly interested in how all the different types of SCSI can
inter-operate.  That is, if I've got SCSI gadgets with one or more
of the above attributes, what restrictions are there on using other
SCSI gadgets (with different attributes) on the same SCSI bus?

Thanks in advance.

I recently bought a used Fujitsu M2261 SCSI disk (357MB) for use on my
PC.  I already have a Seagate 296N (84MB) disk attached to the system
via an Adaptec 1542b SCSI adaptor.  The Fujitsu is an external drive,
so I removed the terminating resistors from the Adaptec card as the
instructions stay to do (the Seagate is internal).  All of this is in
a generic clone 386DX-25 system with 8MB RAM, AMI BIOS, C&T Chipset.

I am able to use DOS (MS-DOS 5.0) FDISK to format and partition the
Fujitsu, but I can not get it to work as the boot disk.  When I
disconnect the internal Seagate and readdress the Fujitsu as Drive 0,
I can boot from a floppy, but not from the Fujitsu.  The necessary
system files are all there.  I can copy files back and forth, do
CHKDSK on it, everything works.  I just can't boot from it.  The
system hangs just after printing out the "hardware summary" screen,
at the point where it would begin booting from disk.

Any ideas???  The Fujitsu has *only* the three DOS system files on it.
There is *no* config.sys or autoexec.bat file.  It is partitioned with
a 100MB active Primary DOS partition and a 257MB Extendend partition
with a single logical drive.

This drive orginally was formatted for a NeXT workstation with 1024
byte sectors.  I reformatted it using the ROM BIOS program in the
adaptec at DC00:6, which put it back to 512 byte sectors.

Many thanks,
Jim

HELP!
	I am currently attempting to install a SCSI drive in a Dos Machine.
I am using a CONNER SCSI drive with Ultrastor's Ultra14f Controller.
Every time I try to load windows it just freezes.  I have the controller
configured for ISA rather than busmaster and the USPI14 driver loaded.
I can load and run Dos with no problem but Windows doesn't want to get past
the splash screen.
I have tried setting the VirtualHDIrq off in windows system.ini but I can't 
get it to work.

I am posting to this group rather than the windows group because this appears
to be a SCSI problem.  

Thanks in advance for any advice.

Hello
I have great problem to get a HD running under OS/2 2.0 and the ADAPTEC 1542 B:
It is a SilberDisk 2 from sinfoni in Gremen, Germany,
a 3,5 " IBM disk with 1200 MB netto, 5 years MBTF,

AT 386 33 Mhz, 16 MB, 64 KB Cache, ATI Graphics Ultra.
I got a set of EPROMS special for a IBM drive with these numbers:
        420418-00 C BIOS C900                   
and     434104-00 D MCODE=F03E                  
and it did not work. The dealer says now, that he is waiting for a kit from
ADAPTEC (Giga-Kit for MS-DOS?), that should solve the problem.
I tried to install the drive on my running OS/2 2.0 system as disk 4,
FDISK-PM recognized the drive inconstantly with 1023 MB capacity, you could
partion it then, but after rebooting and while formatting their was an
error "can not write filesystem" or so.
I tied it also on a second PC (AT 386 40 Mhz AMD, 8 MB, ID 0 for the drive,
single at the SCSI-bus, and I startet the installation of a new OS/2 2.0,
I could come into FDISK, again 1023 MB, I set partitions, while leaving the
FDISK there was an error...
And now the questions:
Do you know systems running OS/2 2.0 with  disks > or = 1 GB ?
Have I a chance to get this disk to work with the ADAPTEC ?
Perhaps under MS-DOS ? (But I need OS/2)
Are there special EPROMS existing for the ADAPTEC to support these drives ?
Who develops them, ADAPTEC ? IBM ? disc factory ? dealer ?
Or is OS/2 the problem ? I use
AHA154X .ADD   16,150 .... 13-08-92 14:56:20
Or you know that this combination should work, and I made the mistake ?
(There are jumper settings for Master/Slave-Sync and term power)
Do you have a list of drives ( > 500 MB), which work together 
with the ADAPTEC ?
Is it a special disk that works only in a workstation ?
Please answer quick, because it is not a good feeling, if free disk space
is running short and you have a 1200 MB disk, and you can not use it.

Some drive manufacturers take the position that the factory format
plus defect management while the drive is in use are all that is
required. I think a lot of IDE drives ignore format commands as well
(there was a big discussion on BIX about this about six months ago).

My guess is that no actual format is done, and that all the drive does
is go out and write all the sectors with the pattern. If you want to
clobber the header, it might be easier to write the first 100 or so
sectors of the drive with garbage. I used to do that all the time when
I was testing disks and different OSes on PCs.  Perhaps Adaptec or
someone has an ASPI program which will allow you to do this. A drive
can ignore a format command, but it had better not ignore a write
command!

Actually, SunOS 4.1.2 has code that appears as if it'll make things work
OK if you're writing to a tape.  If the seek pointer overflows 2GB, it
puts the file descriptor into "seek offsets are in blocks, not bytes"
mode, and adjusts the seek pointer; as the tape driver pays no attention
to the seek pointer in any case, that shouldn't cause a problem.

However, he may be correct in guessing that Sun sends something to the
driver to put it into 8200 mode; if you use "/dev/rst0", rather than
"/dev/rst8", it will do precisely that.

(In Auspex releases 1.4 and later, we don't use that crappy old Bell
Labs naming convention for tape densities, as we can really have a tape
in slot 8, and "/dev/rast8" should be that tape; instead, "/dev/rastN" is
the drive in slot N in high-density mode, and "/dev/rastNlo" is the
drive in slot N in low-density mode, so you're more likely to get
high-density mode by default than you are with the
"/dev/rst0"/"/dev/rst8" convention, which may explain why he had better
luck on his Auspex - although, given that current releases don't have
the 4.1.2 code in question, I'd be surprised if he got >2GB on a tape on
an Auspex.)

The problem is that Suns can only write a file that is 2-Gig long(whether
it is on tape or disk). This is caused by the seek pointer only
being able to access upto 2-Gig.

The fix is to reset the Seek pointer to zero every 2-Gig. I do not
remember how this is accomplished. 

One way might be to backup individaul partitions as seperate tape files.
Since on Suns partition sizes are limited to 2-gig also this should
work.

Well, a better integrity check (but probably still not *ultimate*) would
be to have a second set of heads for read-after-write, and decompress the
data there, and compare it to the original uncompressed data.

For all I know they might be doing that.  It would be a lot better than just
decompressing the data after compressing it.  That would only test the
compression hardware, software, and algorithm.

We're trying to decide on a 1 GB drive for an HP 705.  From what I can

are different, but I assume they're both SCSI-II.  (The manuals say
something about "differential SCSI", but I have no idea what this means.)

I assume that I can fit just about any 3.5" SCSI-II in the internal bay,
right?  Anything to look out for in buying a drive?  Any recommendations?

I've seen these DEC DSP3105 drives mentioned quite a bit, but I just read in
a trade rag that DEC was introducing two new disk drives at Comdex:

DEC DSP5350			DEC DSP3160
5 1/4" form factor		3 1/2" form factor
3.5 Gb unformatted capacity	1.6 Gb unformatted capacity
11.5ms average seek time	??.?ms average seek time
$3495 list price		$1995 list price

Both disks have
- 512Kb cache
- Embedded servos
- (??? bit) ECC
- Available in 8-bit and 16-bit SCSI-2 configurations (whatever that means)

The phone number listed for further info is (U.S.) (508) 841-3111.

I had found a 3rd party company that would sell me an external SCSI box with
2 Maxtor 2112 3 1/2" 1.0 Gb drives, plus enclosure and power supply, all for
$3500.  I thought this was a pretty good deal until I saw the above (presumably
list) prices on the new DEC drives!  3.5 Gb for the same price as 1+1, or
3.2 Gb (in the same form factor) for only $500 more, and that's (apparently)
list, and not "street".  Sounds too good to be true (so it probably ain't (-: )

I'm curious to know if anyone has experience with or further knowledge about
these two drives.  Are they manufactured by DEC, or OEM'd?  (I presume the
former?)  I'd be thinking of attaching them to either an old Sun SPARCstation-1
or possibly a high-end 486DX/50 or 486DX2/66 PC (running 386BSD with an Adaptec
1742 SCSI controller).  Any compatibility issues or potential problems?  Etc.

Subject: Any Utility To Test A DAT Drive Attached To Adaptec?
Date: 5 Nov 92 23:26:47 GMT
Organization: Mail Group

Does anyone know of a utility that can be used to test a DAT drive
attached to an Adaptec host adapter under MS-DOS?  Strangely enough, I
am getting an Archive Python and neither Archive nor Sytron (makers of
the Sytos tape back-up software) have a utility to just write a pattern
to the tape and then read it back.  Pretty basic stuff...how am I
supposed to test whether this thing works?  Is the only way to backup a
200 meg disk 10 times and then do ten different file compares between
each section of tape and the hard disk?

We just received a application note from Western Digital, Number 071-A,
for the 33C93A. It contains all the application notes for the 33C93A,
there are 22 included, and makes a nice complement to the datasheet.
Among the notes are one containing a select-and-transfer flowchart,
and another which gives a matrix of commands and interrupts, with notes
for each possible point in the matrix.

The WD Literature number given is (800) 832-4778.
