CD burner install woes

Qweasda · Apprentice Joined: 04 Feb 2003 Posts: 152

I couldn't find much info via searching on this, can someone point me or help me? I have a Lite-On 48/24/48x CDRW, I want to hook it up to burn. I enabled ide-scsi as module, and enabled scsi emulation and generic scsi CD rom support, etc and loaded them as modules - no luck. I now have them built into the kernel, no luck.
K3B added this to my /etc/fstab:

/dev/ide/host0/bus1/target0/lun0/cd /mnt/cdrom auto ro,noauto,user,exec 0 0
/dev/ide/host0/bus1/target1/lun0/cd /mnt/cdrom1 auto ro,noauto,user,exec 0 0

Looks good no?
I really don't know what to do.

what does

AFAIK, it will be either /dev/hdb, /dev/hdc, or /dev/hdd (The latter if for example you have 2 hard drives on the first controller, a DVD or CD-ROM as master on the second controller and a CD-RW as slave on the second controller)

That command gave me this:

i compiled all those options straight into the kernel so as to not have to wrry about loading the modules.
i got my cd-rw to work by following the most recent x86 gentoo installation guide.
it does not llok like you have scsi emulation setup properly since your fstab has /dev/ide/... whereas mine has /dev/scsi...
have you looked at how the installation guide says to set this all up?
i followed that word for word except for the modules part

If you won't have to worry about where your cdrom drives are located, the symlinks under /dev/cdroms are updated automatically by devfs. I have this in my fstab:

Yes, I did it right from the manual. This, to be exact:

Oh, I saw that you have to:

which kernel are you running?

i agree with malakin. if you have both atapi support and scsi emulation, the kernel will use the native atapi

and simply the ide driver in the kernel (no scsi stuff necessary)
you should be able to do a:

"ln -sf /dev/ide/host0/bus1/target1/lun0/cd /dev/sg1"
(no quotes)

and k3b should detect your ide cdrw drive.
mine works like this with Arson

Cool, thanks I will try more of this tomorrow. But I did try recompiling my kernel and now when I boot to the new one it goes about 3 seconds past Grub (mounting and loading all the stuff) then says something like "kernel panic: cannot mount root fs..." I tried it two times. I have compiled a kernel at least 4 or 5 times with never this problem. But this is only the second time using a 2.4.20 kernel.

So help with that would be nice.
My kernel is 2.4.20-gentoosources

This is my first post to the forum. I must say this thread interests me, as have a nice new Gentoo SMP box, but I can't seem to get my Samsung CDRW/DVD Combo drive recognized. I've been doing the S & L thing for a few days (Searching and Lurking) but have yet to find anything that has helped me get my combo drive operation. Reads cd'sfind, Mounted on /dev/cdrom

Evern with "hdc=ide-scsi' in grub.conf as a kernel paramater.

I've got all the probper scsi items compiled into my 2.4.20 rc1 kernel, and at boot I get this error:

Mar 2 14:45:32 blade kernel: hda: WDC WD400BB-32CLB0, ATA DISK drive
Mar 2 14:45:32 blade kernel: hdb: WDC WD600BB-00CAA0, ATA DISK drive
Mar 2 14:45:32 blade kernel: hdc: SAMSUNG CDRW/DVD SM-332B, ATAPI CD/DVD-ROM drive
Mar 2 14:45:32 blade kernel: hdd: WDC WD1200BB-00CAA1, ATA DISK drive

Mar 2 14:45:32 blade kernel: SCSI subsystem driver Revision: 1.00
Mar 2 14:45:32 blade kernel: kmod: failed to exec /sbin/modprobe -s -k scsi_hostadapter, errno = 2

I think that the ATPI is 'owning' it before the SCSI gets a chance.

I suppose I will go and disable ATAPI for the Samsung, or compile it as a module, and see how that effects the SCSI detection.

I mean what good is this Dual 1600 Athlon if I can't goof off and watch a movie when I am supposed to be working?

OR even burn a new Gentoo ISO.

Overall, having been through other distros, I like Gentoo the best and getting SCSI CD burning and DVD working is more of an interesting dillemma to solve and learn somehting new than it is something for me to B*&% about

After coming through Debian, Slack, Mandrake ( Nice but never lives up to its billing IMO--there is ALWAYS something broke in it), I think I like Gentoo the best, as I have exactly what I want. And waht I want fits into less than a gig on my drive. Even if it won't burn a CD.

Here is how I got my combo CDRW/DVD ROM/CD drive working:

I deselected ATAPI CDROM in my kernel, made it a module in case I need it later, I can just plug it in.

When you do this, the hdx=ide-scsi seems to take effect, your cdrom device will be, or mine is, /dev/sro

"cdrecord -scanbus" reports it to be at 0,0,0 and I can burn CD's.

Mplayer complained that I did not have /dev/dvd and refused to play the DVD disk i shoved in the drive and mounted. sigh

I made a link:

ln -s /dev/sr0 /dev/dvd

Now Mplayer will play the disk too.

I have a similar problem to you Qweasda "cdrecord -scanbus" comes back with the same error (Cannot open '/dev/pg*).

You could try doing "cdrecord -dev=ATAPI -scanbus". This shows my IDE burner (and DVD).

Burning is simply a case of "cdrecord -dev=ATAPI:0,0,0 /path/to/file(s)"
(Where 0,0,0 is the burner from scanbus.)

Not an ideal solution but it works for me.....

P.S. It's my first post

I had a similar issue with Gentoo-Sources-2.4.20-r1.

I have a dvd player (hdc) and a CD burner (hdd), and with Gentoo-sources-2.4.19-r10, I could have the dvd as an ATAPI, with the CD burner emulated as SCSI with the hdd=ide-scsi kernel parameter.

WIth 2.4.20-r1, I could only get them to be both ATAPI, or both SCSI emulated, not split with one each way. I've gone back to Gentoo-Sources-2.4.19-r10 for the time being.

I haven't experimented yet with the other sources out there. Has anyone with a similar setup been able to load two CD/DVD devices, one each way, with 2.4.20? If so, which sources, and please post your .config!

Thanks

I am getting this error too. Passing hdc=ide-scsi to the kernel does not seam to work with gentoo-sources 2.4.20-r1

Current workaround from another thread:
Leave out ATAPI CDROM SUPPORT from kernel, use SCSI emulation instead...

Just wanted to say i got the same problem with the latest gentoo-sources
