I seem to have everything working fine for the cd-rw, I found a modules.conf that was similar to the one Ray gave me and I tweaked it to fit my system. But I couldn't seem to duplicate cd's? I have a dvd already and it is not recognizing it, do I need to activate it with the ide-scsi? I tried adding the one line below to activate it but it doesn't seem to show up. I even tried to put hdc=ide-scsi in lilo.conf to help point at, but still no luck? any clues as to how to activate it for the cd burner programs to read it. here is my modules.conf:

I can access them both the dvd and cd-rw through linux ok, just not the dvd with the cd burner programs (KOnCD or X-CD-Roast). if I type cdrecord --scanbus it only recognizes the cd-rw drive.

Strange, it's usually the writer that is the problem. I know nothing
about KOnCD, but I've used X-CD-Roast to copy audio tracks from _my_ CDROM, which is technically a DVD now that I think about it. I read you as saying you're trying to copy audio tracks.

Your modules.conf looks reasonable.

Both of my devices work through ide-scsi. If I want to mount a filesystem
from them, one of them is/dev/scd0 and the other /dev/scd1. You say you can access the dvd ok through linux, except from the cdrecord or the graphical front ends, so which device do you access ?

It's the best part of a year since I got my setup working, so the detail
is getting a little hazy. I'm assuming both the DVD and the CDRW are ATAPI devices and using SCSI emulation, but your comment that you added the alias for scd1 makes me question exactly how you have them, and the kernel, configured. My memory says that if you compile ide-cd into the kernel you will not be able to use a CDRW as a scsi CDROM. Hmm, apart from writing to the CDRW, can you successfully mount an (iso) data CD in it using /dev/scd0 ?

Also, which kernel ?

If I read this right, the CD-R/W on hdd works fine, but a separate DVD drive on hdc does not work (in SCSI-IDE emulation).

If the DVD drive is an IDE drive, you can either access it as an IDE device -OR- add it to this "ignore" line and let the SCSI-IDE stuff pick it up. But you can't do both.

But ... in the modules.conf file, you only have one IDE device in the ignore line:

Quoted 1 line

options ide-cd ignore=hdd # tell the ide-cd module to ignore hdd

You need to tell the IDE stuff to ignore the DVD drive as well (apparently hdc from what you wrote below) if you want the SCSI-IDE modules to manage it. (Once again, I'm not sure of the exact syntax, since Debian handles modules a wee bit differently from the RH-descended distros.)

This is all a guess, of course, since I'm interpolating a lot to fill in blanks. How, for example, do you now access the DVD for playback? I'm guessing /dev/dvd symlinks to /dev/hdc, not to /dev/scd1 . If so, that's a sure sign that you haven't moved it from IDE to SCSI-IDE.

BTW, Ken, I have IDE-CD compiled in my 2.4.17 kernel, and I can access my CD-R/W just fine. I do need to include an append= line in lilo.conf telling the IDE stuff to ignore hdd, so the SCSI-IDE modules can later grab it. I don't know if Mark's use of ignore in modules.conf completely substitutes for this, or if his method only works when ide-cd is a module.

I may be jumping in the middle of a converstion here, however from experiance my comments are pasted inbetween the lines below.

options ide-cd ignore=hdd # tell the ide-cd module to ignore hdd

^^^^^^^^^^^^^^^^^^^^^^^^^^

Why exclude an ide cdrom, if i do not exclude my cdrom which is also /dev/hdd xcdroast finds it and i am able to use both cdroms.
exclude it and i cant use it in xcdroast.

It will only see the cd-rw because you have excluded /dev/hdd via /etc/modules.conf

You can indeed use ide-scsi for 2 cdrom devices, however xcdroast is somewhat funny when it comes to 2 scsi devices.

Possably a question of having one ide device defined in /dev as (possably) /dev/cdrom1 > /dev/hdd ???

Also, which kernel ?

I dont think kernel version's come into this question, more a question of what is compiled into ones kernel.
I always say use a bog standard kernel (example of that is the distribution kernel installed when you installed linux). Too find out whats going on of course...

O yes and if my comments are considered unvalid, sorry..

Mark, let's keep this discussion on the list, please. I've added it back here in a Cc:.

If you run the command "ls -l /dev/cdrom", you will (almost certainly) find that it is not itself a pseudofile entry. Instead, it points to something else, probably /dev/hdc . That's what a symlink is, sort of (read "man ln" for the details).

Once you moved the drive to the IDE-SCSI driver, it was no longer accessible through /dev/hdc, so the /dev/cdrom symlink no longer works. You now have to access it at ... well, I don't really know, but /dev/scd1 is a good bet.

The mount points you are using are set in /etc/fstab . In there is (probably) a line that tells mount to mount /dev/hdc on mount point /mnt/cdrom, and to mount whatever the pseudoSCSI-CD-R/W device is (maybe /dev/scd0) on /mnt/cdrom1 . Or the mount points may use the symlinks /dev/cdrom and /dev/dvd instead.

In any case, once you know where (in /dev) the device pesudofile entries are, you can edit /etc/fstab so the mount points connect to the right devices (or to suitable symlinks).

As before, this includes a lot of guessing, based on teh way my Debian systems set themselves up out of the box. YMMV as to the dtails, but this should be enough to get you started in teh right direction.

oooops.. I don't know how I overlooked that, several times even. It now works fine, I just burned a cd with X-CD-ROAST. But now I can't seem to read my DVD? I unmounted it and then accessed it again from my shortcut icon on my desktop but it just comes up blank.

I don't have any symlinks that I know of. I have never used symlinks before. I have been accessing my dvd as /mnt/cdrom and cd-rw as /mnt/cdrom1. but neither work now to read my cds. can I use symlink to give them a new name that I can access as ide to read them? or is there a way to access them as scsi devices?

sorry about that, I noticed the other previous ones went straight to you also. I didn't catch it before, but I got this one:). Usually when I reply it automaticly goes back into the group instead of to the sender.

you're right (except fstab uses /dev/cdrom as hdc and /dev/cdrom1 is hdd), and that is why the dvd stopped working. When I installed the cd-rw it linked to cdrom, which is the dvd. the cd-rw is cdrom1. now that I have dvd as ide-scsi it is now cdrom1. will it mess up anything if I just rename crom1 to cdrom and vice-versa so drive 0 is cdrom amd drive 1 is cdrom1. it is confusing having drive 0(cdrom1) as 1. as for it not working after the changes, it was the burner programs wanting to have the cd ejected, it resets the cd somehow, mad a bad cd curn as I was burning too fast for the prgram and got data underflow. I slowed her down and everything is running pretty smoothly. I've done about 5 tests so far with no glitches yet (fingers crossed).

good guessing. You were right on 100% both times with a couple minor (obvious) changes on my end. The only problems I really had were a few program glitches and me being in too big a hurry and missing a command or two.

Again, thanks for the help.

Thanks, Ray. I always find the interactions between ide and
scsi-emulation confusing.
