Delayed Write Failure -- help

I'm getting Delayed Write Failure errors when trying to access an old
internal Zip drive. What does it mean?

I also get occasional I/O errors. What does that mean?

I want to remove the Zip drive when I'm done, and reuse the IDE cable
and the bay to install a new DVD writer. This bay is the 2nd device
-- the first device is an older CD writer, which works just fine.

I don't know what the errors mean or where the trouble is. If the
trouble is solely with the zip drive itself, no problem. If the
problem is with the settings, IRQ's, IDE cable, or CD/DVD master-slave
(primary/secondary) configuration, then I need some help.

FWIW, your new DVD drive will most likely need a new cable too; that old
zip drive probably uses a 40-conductor cable, you'll need a newer
80-conductor cable for the DVD to work at max speed. If it's a retail
drive it'll come w/ the right cable, if OEM you'll need to acquire one.

Good point. It's retail, so I presume it has a new cable. But I want
to keep the old 4x drive, too. How do I hook the new one up on a
separate 80-conductor IDE cable?

I'm told that many of the new drives won't read disks with paper
labels. I have quite a few disks with paper labels from the bad old
days before I knew better. I want to keep the old 4x for that, for
emergency, and just to play CD's while I'm doing other stuff.

you don't, just replace the old ribbon cable w/ the new one, to both
drives. Keep the old drive on the same connector as before, either the
very end one or the one a few inches in from the end; changing it could
mess up your drive letters.

OK. So the 40 & 80 ribbon cables still fit into the same plug-ins,
sockets, whatever they're called. Good. I'll leave the old CDRW in
the same bay just because I don't like moving hardware. The New DVDRW
can go in the 2nd bay, where the Zip drive used to be.

I'm not too worried about drive letters. I can always straighten
those out later. Still, it's a good point and I'm glad you alerted me
to the possibility.

I think today shall be new DVD//RW hardare installation day ... :-)

Hi Frodo,

I hope you can continue to help me. The Zip drive is history. I've
screwed the new DVD drive into the bay. I set the jumpers to SLAVE.
The old Mitsumi 4x CD drive is still in the original bay where it was
installed in 2002.

The installation guide leaves something to be desired.

You said I'd need a new IDE cable -- this DVD drive didn't come with
one, yet it was sold as Retail. The Accessories checklist did not
mention an IDE cable. I'm confused about 40-conductor and
80-conductor cables. What should I do?

I hooked the sound cable to the DVD writer. There are little copper
strips on the plastic ends. I plugged it in so the little plastic
strips face DOWN. Is that right? I haven't plugged it in to the
computer yet -- just into the DVD writer.

For requirements, the DVD box says: Pentium III 800 or faster, but
the Installation Guide says Pentium III 450 or faster. My processor
is Intel Pentium 4, 1.6GHz. I think that means I've met the minimum
requirements either way. Is that right?

The Install Guide says it comes with software. The only software I
got was Nero 7 OEM, which is not important to me. The Guide refers to
a CD with manuals on it, but I don't have that CD; so I cannot check
for info about the IDE cables (40 vs. 80) or about the sound-cable
hookups.

The DVD drive is AOpen DVD Rewriter Model DSW1812P-470.

Can you help me with the cables?
Do I need any special software to get the DVD drive to work? I'm
using Windows Home SP2 with all updates.

Thanks!

The 80 wire cable supports the higher UDMA rates. What the 80 wire cable
does, is includes 40 ground signals, and the ground signals are there to
reduce crosstalk and control the transmission line impedance. You get
better signal quality, and potentially a lower error rate, with the
80 wire cable. The 80 wire cable also typically support cable select,
which the 40 wire cable may not do.

To test the drive and make sure it is at least partially functional, you
can still use the 40 wire cable for now. The driver can detect what kind
of cable is being used, so the supported transfer rate will be determined
accordingly. (The ATAPI standard says it can be detected most of the time,
but in fact there is no guarantee that the driver can figure out the cable
type.)

http://www.pcguide.com/ref/hdd/if/id...Cable80-c.html

I wouldn't bother with the sound cable. If you place an audio CD
in the drive, the computer can use DAE (digital audio extraction)
to pull the CD audio across the ribbon cable. The digital samples
go to your sound chip and from there, to your speakers. The analog
cable, depending on the qualities of the sound chip input, can
pick up noise, if the analog input is not perfectly differential
(good common mode rejection). So for that reason, the sound
cable may be a waste of time. I'd try it without the sound cable
first, and only worry about it, if the sound is so bad you want to
try something else. None of my optical drives have sound hooked
up, and I'm careful to unplug the CDROM sound cable entirely,
so it cannot pick up electrical noise like an antenna.

Some optical drives have a digital output, which I've read is
SPDIF, but it was also suggested that the levels on that interface
are not standard. I don't know where I'd plug that, in any of the
computers I own, because they don't have a working SPDIF_in.

Nero will help if you want to do some burning. Nero may install
an ASPI layer. But if you just wanted to use the drive for
reading installer disks, the driver in your system already might
be good enough for that.

Hi Paul,

(Are you Frodo?)
Your post was really helpful. Does an 80-wire cable still have a
40-pin connector, just like a 40-wire cable does? The IDE cable I
currently have was installed in 2002.

I found an AOpen manual online; it's generic for its DVD Rewrite
drives. It said that having the DVD set as Master is "recommended"
and would be "best" -- but didn't tell why. Currently I have it set
as secondary. The Manual showed configurations for sharing DVD & HD
on the same IDE cable. It did not show any DVD + CD on the same
shared IDE cable. Will the Mitsumi 4x from 1999, which is now set as
Master, is not going to limit the new AOpen DVD drive's capabilities?

I've seen some IDE cables online that are not flat ribbon cables; they
are round, so easier for me to fiddle with, plus they leave more air
circulation space inside the tower. Do you think they are worthwhile?
If I get an 80-wire cable that supports cable select, then I don't
have to worry about Master/Slave ever again, right?

WOO-HOO! I've got me a new DVD drive! Thank you for your help, Paul
& Frodo. Once I learned how to do it, it wasn't really that hard. The
sound without the separate analog sound cable is about the same, at
least on MP3's.

Nope. I figured you were sitting there with nothing to do, so
tossed out a link to a disassembly web page.

The connector is 40 pin for both cable types. They both have to fit
the same motherboard and hard drives after all.

I've tried looking at the standard, for guidance as to what to expect
for behavior, and nothing distinctive stands out when I browse the document.

This is what it says for Device Selection:

"3.1.34 device selection: A device is selected when the DEV bit of the
Device register is equal to the device number assigned to the device by
means of a Device 0/Device 1 jumper or switch, or use of the CSEL signal."

In other words, both drives on the cable, get a command written to them.
The Device Register in both drives, receives the same number. It is up
to the drive, to compare the bit in the Device Register, against a
0 or 1 seen on the IDE cable or via the Master/Slave jumper scheme.
Only one drive should detect a match at a time. If the jumper on both
drives was set to Master, then both drives will detect their Device
Register matching at the same time (which sounds like a bad thing to me).

For modern drives, the idea was supposed to be, that you could mix fast
and slow devices on the same cable. And there would be no interaction
between them. Older gear may not be so well behaved (because otherwise
there wouldn't be urban legends about which way is better, if there
wasn't some gear that didn't play nice).

I'd try DVD as master and the Mitsumi as slave, and just see what happens.

Think of Cable Select capability, as offering a third setup option for
your two devices on the cable. Master/Slave, Slave/Master, CSEL. For
cases where gear refuses to be detected in the BIOS screen, you can try
CSEL for both drives and see if that works. The 80 wire cable is modified,
such that the two drive positions on the cable, receive a different value
for the signal, so one drive gets a 0 and the other one gets a 1. One
drive is master and the other drive is slave, and since you aren't really
attempting to control which is which, the implication is that whether a
drive is master or slave, doesn't matter.

As long as the configurations you try are valid ones (i.e. no master/master),
you aren't going to hurt anything. You can benchmark and test until
you are satisfied that the setup works, and works well, and then move on.
For example, Nero has a speed test, and you can see whether a DVD reads
at a decent speed or not. If there is a review on CDFreaks.com for the
drive, you can compare your Nero performance, to the graphs on there.

It is more important to get master/slave/csel right on the first try, if
you are running a business and every second counts. For a hobby situation,
it really doesn't matter if you have to spend an extra ten minutes, trying
a different jumper combo.
