Hello dudes,

I'm invoking the power of usenet in order to help me fixing a quite
annoying problem : i can't use burn CD with my cd driver. Yeah i know,
what a common issue, but you're kinda of my last chance..

First of all, i've to say that, Slackware is such a great distro, and
untill now, everything was just perfect.

As you probably assumed, it's an ATAPI device, and i'm running kernel
2.4.29, it's the standard kernel (called bare.i).

I gave the kernel the 'hdc=ide-scsi' option (using GRUB) and I can see
it in dmesg's output, i also know that the ide-scsi module is loaded,
but i can't burn anything..

My question is that : what can I do, what should I read ? Perahps load
an extra module ? Or is my device an exotic one that should work fine
with another well-tuned kernel ?

And for information, i read somewhere that i have to load sr_mod, but
modprobe can't find it ! (normal behavior with bare.i ?)

And before you ask, dmesg, cdrecord -scanbus and lsmod 's outputs
follow (perahps i shouldn't..?).

Hope you managed to understand me..

Thanks in advance.

Here is the output of demsg (after trying to burn something) :

As root type this command:

cdrecord -scanbus

That will show you where your CD burner is -- typically 0,0,0 if you
only have one.

Then to burn type:

cdrecord -v -eject dev=ATAPI:0,0,0 someiso.iso

That will burn the file someiso.iso. If you get a buffer overrun error
try adding speed=0. A Cd burner can't wait for data, so if the buffer
runs dry you get a coster.

You can create an iso from a directory of files with mkisofs.

NOTE: Any modern Slackware kernel does *NOT* need hd(whatever)=ide-scsi
appended to GRUB or lilo.

Just guessing but you may need to read the CD-Writing-HOWTO
very carefully where it applies to ide-scsi modules
such as sg and sr_mod and ide-scsi and their order of loading.

Particularly pre-install options in modules.conf That is
where you put the options outlined in 2.1 of the HOWTO.

If your writer is usb it may not be supported.

Well, you gave us everything but the output of cdrecord. How about
laying that on us?

> cdrecord -scanbus finds my device (but why is it 0,0,0 and why is my
> usb bus listed ?) :

It lists as 0,0,0 because you have no real scsi controller and this was
the first scsi "device" it found. USB mass storage devices also use
SCSI. SCSI's not just about hard drives anymore; it's really become a
generic hardware access layer I guess you could say. IIRC firewire uses
SCSI too?

"hdc=ide-scsi" is right for the 2.4 series kernels, and your dmesg output
shows that the drive is being assigned to /dev/sr0 all right.

My first thought is, are you trying this as a normal user or root? If you
haven't tried it as root yet it may be a permission issue.

Ideally you should have something like this...

$ ls -l /dev/sg0
crw-rw---- 1 root cdrom 21, 0 1999-04-13 05:24 /dev/sg0

(/dev/sg0 is the device use to write to the CDRW, as opposed to /dev/sr0 (or
scd0) which is used to read)

And your user account should be a member of the cdrom group so that it has
rw access to the drive (or you can just chmod 666 /dev/sg0, to give every
user access).

If you have tried as root, then we'll probably need to see the commands +
error messages you got.

Nope, that's good, gives us the basic info to check. Only thing missing was
the command you used to try and burn a disc and it's output.

If your device is as /dev/sr0.. you can use it to burn cds as well, my
cd-writer is /dev/sr0 and i can burn cd's...
If you are sure that ide-scsi module is loaded, and that the line in
"lilo.conf" is correct (hdc=ide-scsi), check the cdrecord -scanbus, that
will show to you if you have your cd-writer installed. If so, try to use
gtoaster as your burn software, must remind you, that if you are trying
to burn cd's with a normal user, its normal that you can't burn
anything, try first with root.

Any 2.6.x kernel. myardbenoit@gmail.com is using 2.4.29, according to his
dmesg output, and so still needs hdc=ide-scsi. The kernel option doesn't
need spaces.

Hello, first of all, i would like to thank you for your help, even if
it doesn't work, i've learnt a bit about devices assumed as SCSI.

Mmh i'm probably ill, but can't find it ...

Also, there is a thing that looks very strange in dmesg's ouput, it's
the 3 lines.. doesn't it matter ?

According to ksudjsd i tried to burn cd as root, but the result is the
same, so this time, here is the output of the command (i burn using
xcdroast, sorry but i'm not used to burn in command line) :

Just a wild guess, but you haven't been trying to burn with the same
disk for all these tests have you? If you had a partial burn on the CDR
on one of the earlier attempts, it may be a coaster now that will cause
all future attempts to burn on it to fail as well.

Ahah no i am not.. and well, if it was the case, i'd be very confused
of bthering you all..
Anyhow, no cd have benn burnt yet...

btw, i tried a bad thing.. i probed a module called 'st' (listed in
/etc/rc.d/rc.modules just after ide-scsi) and i tried to burn, it
worked this time, but there is still an error, and i can't access my
cd. cdrecord told me it couldn't fix the cd.

That's all...

Well, dudes i think i'd better to stop there now.. i'll try another
kernel and see if it's possible to probe sr_mod..

Big Thanks to all, bye.

PS : i have some invitations to gmail.. just drop me some lines..
