Yep, it looks like the old drive was set to SLAVE. However, I just
changed the new one to CS and copied a bunch of stuff to it from my
first drive. Then I deleted some stuff and copied a whole bunch of small
clipart pics to it, and then deleted some of them, and after that I
copied a huge ISO file to it, which is almost 1gb in size.

After all of that, I defragged that drive with no problem. It appears
that it needs to be set to CS. Maybe that was the whole problem. I'll
copy more stuff to it and delete other stuff and see if it keeps working
properly now. So far, so good!


I hesitate to ask, but when you say "the old drive" above, do you mean
the CD drive that failed years ago, or do you mean the HD-that-was-G/H/I
whose failure started this whole saga? If the latter, I wonder if
setting that to CS might have cured the original problem )-:!

There is no CD drive involved in any of this. In fact the CD drive in
this computer died years ago. I really dont have any need for one on my
Win98 machine. I have the Win98 install files right on the HDD. I dont
play games or anything that needs a CD.

I do have a CD player on my XP machine, but rarely use it. But I would
need it to reinstall XP, and once and awhile I copy a music CD and turn
it into MP3 songs for my MP3 player. If I want to listen to CDs, I have
a regular CD player on my stereo.

Anyhow, I was referring to my old 2nd drive / Slave (G: H: I.


I ma tempted to try the actual Master and Slave settings with the
jumpers and see if that works. I dont know if one way is better than the
other, or not? Does anyone know which jumper setting is the best?


Does anyone know whether using master/slave jumpering with a cable on
which CS works might cause problems?

I never understood how that CS works, or why it's even an option. Older

If the cable truly has the same connections on all three connectors,
then I can't see how it's selecting either. I know floppy drive cables
had a twist in the cable.

Yep, floppy cables do have a twist, but not these IDE Hard drive cables.
So how that CS works is beyond my comprehension. I do know that for


Maybe there's an internal break in one line - so the cable from the mobo
to the first connector is 80 way, but between them is 79 or 78 way? (I
take it there's nothing obvious like one of the connectors having one of
its holes blanked.)


This is a brand new cable. Of course anything can be defective.

Ah, I've just looked:
https://en.wikipedia.org/wiki/Parallel_ATA#Cable_select says it is done
using pin 28 - often just by omitting the contact from the middle
(slave, grey) connector, so you'd have to look extremely hard to see it!
It also says line 28 is only used so the drives know which they are, not
for control by the mobo, so if the drives are jumpered as master and
slave anyway, it is ignored (and that doesn't have to be master at the
end). So you can try it if you want. When the controller says "master
drive, please respond", both drives receive the command, but only one of
them responds - either because it is jumpered as master, or because both
are jumpered as CS and one of them knows it is master. (Apparently also
"drive 0" and "drive 1" - apparently "master" and "slave" don't actually
appear in the specification.) Which does suggest that having one drive
"hard jumpered" and the other as CS _could_ cause problems, depending on
position on the cable.


Ok, that explains it....

awhile I had the Master drive on the first connector and Slave on the
last connector. THAT IS WRONG, but it was that way for a year or more
and worked fine. Maybe it dont much matter which cable comes first, but
according to several articles, the last connector goes to the first
drive (which seems backwards).

No, as the article explains, if you only have one drive, and it was
connected to the middle connector, you'd have an unterminated stub of
cable, which isn't good electrically (reflections and so on). Apparently
for the 40 as opposed to 80 cables that _was_ the case, as they just
left out line 28 to the second connector (i. e. master was on the middle
connector).


I better understand this now. I know I have the cable right now, and
since I changed that jumper to CS, it looks like everything works fine
now. (At least so far). I have copied and deleted files and defragged
and scandisked, and ran Norton Dick Doctor. I even ran scandisk from
Dos. Everything checks out ok.

I sort of am wondering if the problem on my old slave drive may have
been caused by the jumpers being incorrectly set, but I had them drives
that way for at least 2 years. I'd think that would have shown up a lot
sooner.
