[unix-pc.general] Help with 3B1 2nd drive. Update

sbw@naucse.UUCP (Steve Wampler) (06/10/89)

I'd like to thank all the people who have tried to help bring
up the 2nd drive, and give a status report.

1. It's not the CDC drive.  If I switch it with the internal drive
	(and make the appropriate jumper/terminating register
	changes) I can use it (all 80+MB, so the WD2010 and P5.1
	upgrades work), and cannot reach the 2nd drive (the one
	that was the original.

2. Since I could get it to work that way, I built a file system
	on it holding the foundation set, then switched them
	back.  Since it's been formatted and has a file system
	on it (presumably in /dev/fp012, no?), I should just
	be able to mount it as the 2nd drive.  However, mount
	gives back a "Cannot open /dev/fp012" command (the
	light on the drive *does* come on just before this).
	One interesting thing is that, between the "Cannot open"
	and the "/dev/fp012", it sounds as though the heads
	on the internal drive (drive 1) are being moved all the
	way in (or out).

3. Since I'm doing this now through unix, I consulted unix.log
	and found several entries of the form:

HDERR  ST:51  EF:10 CL:FF00 CH:FF00 SN:FF00 SC:FF02 SDH:FF28 DMACNT:FFFF
DCRREF:90 MCRREG:8500 (and then the date)

Is any of this informative?  I assume the EF:10 is the response 10 I've
been seeing using the diagnostic disk.  I haven't tried the suggestions
that John Milton made yet, as I'm not sure which end of a soldering gun
to use, and my normal hardware support is out of town for three weeks,
but if anyone has other suggestions, I'd appreciate them...

By the way, what happens if I run the system with only 1 drive connected,
without a termination resistor in the disk bus?  (cables in place).
Switching those resistors around is a pain, especially on the CDC drive,
so I'd just as soon find a configuration I can stay with during this
testing.

Also, Gil mentioned that 7300 won't take a WD2010 (old data separator).
I don't have a 7300, but I do have a fairly old 3B1 (case is marked
11-6-85) and the motherboard had a jumper in place from pin 3 of 13K to
pin 2 of 13N.  I assume I'm alright (given I can format the CDC with
1072 cylinders and 9 heads/tracks).

Thanks again!

Re: the 7300 not "taking" a WD2010 ...

sorry to burst your bubble, but I own UNIXPCs that spread the gamut, from
the earliest machines (.5MB and "7300" logo) to the last production week of
the 3B1, and the WD2010 chip work fine in *ALL* of them.

I have spoken with Western Digital (in Irvine, CA), the mfg. of the WD1010
chip (stock UNIXPC) and of the WD2010 (the upgrade chip): except for the pin
4 of the WD2010 (not connected), they are functionally IDENTICAL and can be
considered a pin-pin replacement.  By "not connected" I mean the pin is "N/C"
on the WD1010, and there is no trace leading to/from that pin on the UNIXPC
motherboard (that I can see).  They haven't yet sent me the data sheets for
the WD1010 and the WD2010, but the App Engineer in Irvine and her counterpart
in Sunnyvale both assured me they can be used interchangeably (in the UNIXPC).

The only difference of note is the WD1010 handles a MAX of 1024 cylinders,
and the WD2010 handles a lot more (at least up to the requirement of a Maxtor
XT2190 (1224 cylinders)).

If you're intending to use the WD2010 with a HD having more than 1024 cylinders
your MUST, repeat *MUST*, get the new diagnostic disk that has cognizance of
the WD2010 and can properly format and verify beyond 1024 cylinders; after the
HD is formatted, the stock (at least 3.51) kernel operates fine with > 1024 cyl

NOW: "where does one get the new diagnostic disk?".  I don't know the genesis
of it, but it is "available"; I uucp'd my copy from another UNIXPC site since
I urgently needed to format a Miniscribe 3085 to its full 1170 cylinders ...
it has been working GREAT, and I intend upgrading my other two systems the
same way.

Whence indeed.  Would someone who know the genesis please post.
Also, is it PD?  I just want a bigger HD (one) for now.  So far
I have gleaned that CDC (Imprimis?) makes several good (fast)
ones, I need a WD2010 controller, and "the new diagnostic disk".
Where do I get one?

	Well, I have one of the first 7300's sold, and the 2010
	does not work.  Constant disk errors.  My understanding is
	that the early 7300's had off-chip data separators instead
	that conflict with the 2010's on-chip one.  I have the complete
	explination somewhere, and when I find it, I will post.
