It's probably PAM setting the owner when you log in.

It is a PAM setting. Delete the line
Code:
#<console>  0600 <cdrom>      0660 root.cdrom
in /etc/security/console.perms, if you don't want this.

Hello,

Thanks for the info on this problem. I hit is as well and my cdrom burner (a Korean LG) hang and reported similar messages. I'll upgrade from 2.6.10-r1 and make the appropriate changes.

I saw some debian forums have a winge about this same issue. The people here generally take a DIY approach fixing problems and then share their knowledge with the gentoo userbase, rather than doing the former.

For number hours saved finding resolutions to problems on this forum, I'll try and contribute back more!!

"ide-scsi is and always has been a dirty, dirty hack, and its death is appreciated by many, myself included.
Jörg's an asshole and Linus is stubborn, but stubbornly right, imho."

Last question: Which is the best way to use my ATAPI device. I read if you enable ide-scsi in the kernel and use a boot time argument I heard it turns of DMA. Should I use atapi or ide-scsi module (does the latter work with DMA). I want to use modules, because it's reconmended to DMA when watching DVDs for example with xine, so I'd like to switch between the two.

Cheers,

Luke

PostPosted: Tue Jan 18, 2005 9:16 pm    Post subject: mishandled SCSI response to OPC Reply with quote

I have a LITE-ON DVD/CDRW drive that fails when attempting power calibration (OPC). It seems like the drive actually does the proper thing but cdrecord is mishandling the returned status.
Code:

Performing OPC...
/usr/bin/cdrecord: Success. send opc: scsi sendcmd: no error
CDB:  54 01 00 00 00 00 00 00 00 00
status: 0x4 (CONDITION MET/GOOD)
cmd finished after 60.041s timeout 60s
/usr/bin/cdrecord: OPC failed.

I've not worked in SCSI for a while but if I remember, a normal GOOD status was a 0x0, my drive appears to be returning a 0x4 (CONDITION MET/GOOD). I'm going to guess that the manufacturer believes that CONDITION MET/GOOD should be interpreted as power calibration succeeded. It looks like cdrtools is treating the return code as an error and hence aborts without writing the CD.

cdrtools is treating the drive as generic..
Code:

Using generic SCSI-3/mmc   CD-R/CD-RW driver (mmc_cdr).
Driver flags   : MMC-3 SWABAUDIO BURNFREE FORCESPEED
Supported modes: TAO PACKET SAO SAO/R96P SAO/R96R RAW/R16 RAW/R96P RAW/R96R

i stand corrected, it was an evil kernel bug causing the growisofs error mentioned many times in this thread.

this patch should solve it:

Got another report of command '1e' being filtered. This is while attempting to burn a CD-R (using k3b and cdrtools only) on a CyberDrv CW088D/Generic MMC 3, though. I've patched cdrtools to open the device read/write, too.

Ahem, last edit:
This is all on g-d-s-2.6.10-r7 with cdrtools-2.01.01_alpha1 and k3b-0.11.20.

I've just noticed something interesting:
If you try to burn a CDR as non-root with cdrecord dev=ATAPI:0,0,0 it will not work, as we well know. But if you try to burn with cdrecord dev=/dev/cdrom after that, it will not work anymore.

Ok, clear answer, thank you. I think it will also be fixed in vanilla-2.6.11, right?

Simple question here:
To burn a bootable CD, must it be burned -dao? I burned an .iso with "cdrecord dev=/dev/hda /path/to/iso" (which I think assumes tao) and... no boot.
If dao IS required, is there any way I can reburn that same CD dao (i.e... without using another).

I could be wrong but... if the iso itself is bootable (that is, the iso itself has files that let it boot) then if you burn the iso in a regular fashion it should be bootable. If the iso is not bootable, then you will not be able to boot the iso cd regardless I think. You would have to remake the iso with a boot option and then burn it.

First off, I'm pretty sure it's not a problem with the hardware, or medium, considering I've successfully used both to burn the gentoo liveCD under wind0ws.

I've been having lots of problems burning... I've only been using 2.6.9, and now I have 2.6.10 (gentoo-sources). I tried using bashburn, here are the nice messages:
(ran as root, same problem if ran as user)

cdrecord: Asuming -tao mode.
cdrecord: Future versions of cdrecord may have different drive dependent default s.
