Also, don't run your burner using a 80-pin IDE cable, be sure to use a 40-pin one - AFAIK, no ATAPI device should use one of these "UDMA" cables which are often characterised by a blue connector on the mainboard side.


I firmly believe this to be untrue.
ATA66 cables (80pin cables with the colored ends) Will work perfectly
using the Cable Select settings, and often resolve device conflicts.
Give it a try change cable and set device jumpers to cable select. This also allows you you to sepate to optical devices to separate ide buses whilst still using ATA66/100 hardrives.

Kerframil I am havig problems with cdrw speed it records perfectly at x16 but cdrw is x40 and it used to work under Mandrake 9.0 untill one fine day it stopped working I have since moved on to Gentoo.
I have a detailed thread here http://forums.gentoo.org/viewtopic.php?t=53746
Thankyou in advance.

I followed this tutorial and got my burner working. But, I still had to add "ide-scsi=hdc" to my grub.conf. If I *don't* want to do this -- and let devfs handle everything, how/where do I indicate that my cd burner is "hdc"??

I've recently had an annoying problem with my combo CDROM/DVD drive when playing DVD's. On most DVD's when I got to the last few minutes of the program, the DVD player would crash: mplayer, xine, and ogle.

I played around and emerged different libraries, all to no effect. Then reading the Ogle faq I noticed that they recommend using SCSI emulation to fix some strange bugs (I had converted from SCSI emulation to ide-cdrom about a month or two ago). So I recompiled my kernel removing ide-cdrom and including ide-scsi, etc and this fixed the problem.

[qoute]As for the report above from perry saying that the kernel option was needed, well yes, things seem pretty inconsistent. I had that problem also on one machine, but not on the original machine (which worked exactly according to my original instructions above) so I guess you do have to have that in some situations. I can't put my finger on it but there must be some rationale behind it.[/qoute]

Could it have something to do with Via Chipsets:? I've got one and it has to be setup with the kernel option at boot, although I have 2 drives, the second is a plain cdrom and it's running in ide mode w/o prob. :

[qoute]Perhaps devfs isn't too intelligent about determing whether a device is a CD or DVD. In fact, maybe it has no way to distinguish the difference. Have a look at devfsd.conf (the relevant section of which xamn has conveniently posted above, and look at the REGISTER lines and the "Change foo to suit your setup" comments. Maybe they need tweaking for your setup.[/quote]

It got me thinking because mine does the same thing. I suspect what causes it is the emulation mode itself. IDE is the prefered method for IDE devices and scsi is going to be the secondary mode. Due to this, when you build both into the kernel, that is why CDRecord can't locate an IDE burner, the IDE driver has it locked and defined as IDE, thus not allowing scsi emulation a chance to talk to the device. :idea:

hi,

well first to say this guide is awesome, i finally got it working, BUT
while using k3b i have 7 writers now ;) not bad huh?
well, unforunally i just need ONE. The other thing is that my reader is now not visible anylonger, since i got the writer working.

i'm using a notebook with a combo-driver CD/DVD/CD-RW
before using this guide this combo was working on /dev/hdc
my well discovered writer is now /dev/scsi/host0/bus0/target0/lunX, as i said before its there 7 times.

any ideas?

Hey, great guide. Thanks a lot.

I got it working after a while...the hardest part was figuring out that the modules had to be loaded in the right order, and then adding the appropriate flags to the kernel at boot.

Keep up the good work, guys. ; )

Skal!

Thank you for the nice tutorial. I now have burning capabilities.

I use gtoaster to burn CD's and if I try and record as a normal user I get a cdrecord warning about possible buffer underuns. I fixed this by editing visudo and using the command "sudo gtoaster". Works great. :D

Thanks again.

Any pointers on what I should do if it is a external USB one. More specifically a HP 8210e that runs at 4x. One of the many things that I have to have enabled is the mass storage support right?

Hello people, after reading this guide for SCSI emulation, I encountered a weird problem. 1st of all I'm a total newbie when it comes to linux and I couldn't understand this.
I setup my bootsplash (instructions here!: http://forums.gentoo.org/viewtopic.php?t=49036) and when it came to the part of adding the bootsplash screen to the other VT's, everything ran fine until I added the hdc=ide-scsi to the kernel line on my grub.conf. Does anyone have any idea what the problem is or if there's anywhere else I could add that hdc=ide-scsi so it wouldn't conflict with my VT bootsplash screens? Thank you! :)

hi, im new and thought i would ask, in case this isnt the same problem.

i got gentoo on a dell inspiron 5100. everything works except the cd drive.
i installed using the drive, but in normal operation it doesnt let me access anything on the cd. i know it has something to do with scsi-ide stuff, but im kind of a newb with linux. any help is appreciated. sorry i cant provide more info, i don't have the computer here. the cd drive is a CD-RW/DVD drive.

I followed the tutorial and I don't think I'm missing anything but when I did:

Code:
cdrecord -scanbus


I get the following error:

Any help would be appreciated.... also I was wondering if anyone had played with using cdrecord without setting them up as scsi and if this was possible yet.

same for me, would be thankful for anyhelp (with another install 4 months ago on EXACTLY the same box it worked like a charm...)

This is for people who tried every configuration one can think of including the hints from this thread and all efforts were worth nothing....


TURN OFF APIC !!!!!!


In Grub.conf insert option "noapic"
lilo?!?


Sometimes it does magic!
On my system it did.

PostPosted: Wed Dec 10, 2003 3:26 pm    Post subject: Reading audio cds Reply with quote

Having done all this successfully and burning audio cds no problem, is there any way to actually play the cds (using the same device, the burner on hdc)? When I use xmms and try to find the disk, /mnt/cdrom comes up empty. However, if I put a data disk in, xmms finds it.
xmms plays mp3 files fine, I just can't get it to find my audio cds.
I have the cdplayer plug-in enabled and set to device:/mnt/cdrom and dir:/mnt/cdrom
I'm told I don't need to mount audio cds.
I've tried commenting out the line in...modules.d/cdr, no luck.
I've looked all over for a solution and I am totally, completely lost.
Thanks.

For AudioCD, you have to give the path of the device. Should be /dev/cdrom, or /dev/cdroms/cdrom[0|1], maybe also /dev/sr0 (as you enabled scsi emulation), or even /dev/ide?/host?/bus...
Only the last one is the real path of the device, then wether you give this one, wether you give one of the previous, assuming it is linked to the right device.

Hello,

On my computer, I have an IDE cdrom reader and a SCSI CDR writer. I use this post to try to use my IDE cdrom without SCSI emulator. But it didn't work for me. So I decided to go back to previous configuration, by modifying config files for another time. But now, my cdrom reader freezes when I want to mount a cdrom. And 1 or 2 min. after that, all my computer freezes. I get this from cdrecorder (after a long time scan):
Code:

        1,7,0   107) *


But scan in XCDRoast seems not to work and XCDroast freezes.
My SCSI CD burner works correctly, I can burn CD with no problems. I have tried with and without SCSI emul. support in kernel. No success. The link /dev/cdroms/cdrom0 points to ide/host0/bus1/target0/lun0/cd. What sort of thing should I verify?
