IDE Device Conflict???

I have an IDE (maybe EIDE) Sony DVD +/-RW that will not read CD ROMs or
Audio CDs. It does read & write DVDs.
The machine also has a SCSI CD and SCSI CD RW and 2 SCSI HDDs.
The DVD used to work properly.
An IDE (maybe EIDE) HDD was added later.
The problem may well have started with the addition of the IDE HDD, not
sure.

I've always used exclusively SCSI in my desktops so I'm ignorant about IDE.

Is it possible that the addition of the HDD has caused the problem with the
DVD?
If yes, any advice? Web links to study?
If no, any other places to look, things to try?

Thanks for at least reading this,
BF

Not the specific problem you are having. Do you have a floppy drive? If so
boot off of a Win98 startup disk and see if you can read DVD's and CD-ROM's.
If you can read everything then it's a problem in the OS and not with the
drive.

Google for 'cdrom upper lower filters'. This is a common OS problem.

Thanks for the suggestion but the boot hangs after the second "pci buss scan
complete". I tried two different disk with the same result. Boot without
cd-rom support will complete, but is of course useless for my purposes.

Thanks,
I didn't read all 400,000 hits but the first 40 or so dealt with loosing the
drive altogether. My case, the drive reads and writes DVD's fine but will do
neither with CD's or CD-ROMs.

I wondered about that with the SCSI cards you have. If you don't mind
'rolling up your sleeves' try removing all your SCSI cards, just for this
test - that might be what's hanging the system.

Don't think that'll help, plus I can't. OS is on a scsi drive.
The drive read/write both (DVD/CD) prior to adding a aux ide HDD drive. The
ide HDD is just used for storing "junk"
What I will try is removing the ide HDD and see if that restores the CD
ability.
So thanks for the idea, not exactly yours but good enough.
BF
 
I don't recall seeing anything here regarding the jumpering on that IDE
HD. Slave? and the DVD drive?

Bob
 
Agreed, it appears the problem is elsewhere, maybe in the drive itself.
Don't really need it since I have a CD RW too, just a nuisance that it
should work and doesn't.
BF
 
...plus I can't. OS is on a scsi drive.

Yes, you can.
Were just booting off a floppy disk, you don't need the OS drive for that. I
only want you to go as far as a DOS prompt with CD-rom drivers loaded so you
can test the read capability with DVD's and CD's without the OS's
involvement.

Appreciate the response but I think you getting your thread mixed up a bit.
The "I can't" was in response to another suggestion to disable the scsi
drives and reboot.
I did try your suggestion to boot from a 98 floppy but couldn't get to the
dos prompt with cd-rom support (but could get there without cd support)
BF
 
I apparently didn't make myself very clear. :-) You may not have to
deal with it with scsi drives, but IDE drives need to be jumpered on the
drive itself as either Master, Slave, Cable Select, or only drive. If it
isn't correctly jumpered, that can cause unpredictable behavior with
anything on that ribbon cable.

Bob,
As I stated early on, I'm IDE ignorant, but I do know how to set a scsi
device's jumpers so I'm not a total waste here (maybe).
Upon someone's excellent suggestion, I shutdown and unplugged the power to
the HDD and rebooted to find no improvement. Should I have unplugged the
ribbon cable as well as the power to the HDD to test the theory that there
is a master / slave conflict? Would / could such a conflict cause the DVD
part of the drive to function but not the CD portion?
Thanks for your time and bother!

On an IDE, there is a set of pins between the ribbon connector and the
power connector. A 2-pin jumper needs to jumper those per manufacturer's
instructions nd that varies by manufacturer & model. Quite often the
settings are printed on the top or instructions came with the drive.
Otherwise the manufacturers website should have those. That drive should
be jumpered as Slave and your DVD/CD should be Master.

That wouldn't matter. What you did was fine. Have you been successfully
reading/writing from/to that HD? I haven't seen you mention that in this
thread.

Not so sure exactly what you mean by that. Do you mean you can't burn a
CD-R? Do you mean you can display the file listing on a DVD using
Windows Explorer? and double-click and read them? but somehow can't with
a CD? What software do you use for burning? Nero, Roxio, ???

I'm only guessing at this part, but I wonder if your software ignores
the CD aspect of that drive because you have a scsi CD drive set to do
that and there is some configuration problem.

Have you installed your motherboard's updated drivers pack?

Also use the free Nero Infotool,
http://www.geocities.com/sheppola/diag.html
To check that ALL your drives are using DMA(Configuration TAB) and
that the ASPI layers are working.
Also as stated by other posters get the jumpers on the IDE drives
correct.
More general info here,

and,

HTH :)
 
I'll try removing both cables later and will check to see that the DVD is
set as master and the HDD as slave
and yes the HDD works fine (at least as far as I can tell)
BF
 
On the fine advice from Shep© I've downloaded Ahead InfoTool. It informs me
that the HDD is the master and the DVD is the slave.
Before I start ripping things out of the box, I would like your opinion on
the probability that reversing the master /slave setting could cure my
problem?
Nero CD-DVD Speed utility (also suggested by Shep©) reports that the DVD
drive should read and write CDs. But it also shows all functions on my read
only CD as grayed out.

Yes. Good stuff! Also comes packaged with the burner software.

Do you believe it? There's a way to double-check and that's to look at
the jumper settings. What's hard to understand about that is what the
state might have been before you added the HD - a lone DVD sitting there
as Slave? or a HD jumpered as Master and forcing that report?

I've been able to re-jumper HD's by unplugging the power connector to
the HD so it wasn't blocking view & access. Naturally that still was
with the power cord for the PC unplugged to protect myself and taking
normal static electricity precautions to protect the hardware.

I guess the point is that leaving it the way it is sure hasn't solved
anything so far and returning it to a standard configuration gives a
better platform for diagnosis. I make no guarantees and am just one
voice in the wilderness. I can only say the those drives are very
temperamental and all advice that I have ever seen and/or followed is to
have them as Master in that configuration. A lot of people go through
multiple, and I do mean multiple, iterations of pulling drives, swapping
drives, jumpering drives, swapping cables etc in attempting to solve
problems and that includes myself. I'm currently on my 3rd DVD/CD drive
after going almost crazy trying to diagnose problems and returning the
others and am praying that this one keeps on working.

That seems to be correct report.

That's your scsi drive? I dunno. Maybe the tool has a problem with scsi
drives. It shoud read-yes write-no. Or as I speculated upon before,
there might be a configuration conflict between the 2 drives in regard
to CD functions.

Bob
 
I downloaded both of the Nero utilities so could well be confused as to
which I was quoting, but it reports my CD RW as expected and the read only
CD as grayed out. Both are scsi.
I'll go ahead a open the case up in a few minutes and report back. At least
we'll have another benchmark, whether it works or not.
