Problems with Debian and CDRecord

bubkus_jones · 03-25-2006, 10:53 AM

Ok, I'm trying to get my CD burner working in Linux (Debian SID). It worked the last time I installed Debian (which wasn't long ago, I just went back to Windows because I needed to use some software that wouldn't run in WINE). However, this time, it doesn't want to work.

I installed CDRecord, from the Debian mirrors (and once downloading it through Debian's web-based package search tool) and all I get is the following:

Code:

Cdrecord-Clone 2.01.01a03 (i686-pc-linux-gnu) Copyright (C) 1995-2005 Joerg Schilling
NOTE: this version of cdrecord is an inofficial (modified) release of cdrecord
      and thus may have bugs that are not present in the original version.
      Please send bug reports and support requests to <cdrtools@packages.debian.org>.
      The original author should not be bothered with problems of this version.

cdrecord: Warning: Running on Linux-2.6.12-1-386
cdrecord: There are unsettled issues with Linux-2.5 and newer.
cdrecord: If you have unexpected problems, please try Linux-2.4 or Solaris.
cdrecord: No such file or directory. Cannot open '/dev/pg*'. Cannot open SCSI driver.
cdrecord: For possible targets try 'cdrecord -scanbus'.
cdrecord: For possible transport specifiers try 'cdrecord dev=help'.
cdrecord: 
cdrecord: For more information, install the cdrtools-doc
cdrecord: package and read /usr/share/doc/cdrecord/README.ATAPI.setup .

Reading /usr/share/doc/cdrecord/README.ATAPI.setup was no help either. The first thing they ask you to do
is run

Code:

# cdrecord dev=ATA: -scanbus

Which just keeps doing this

Code:

scsidev: 'ATA:'
devname: 'ATA'
scsibus: -1 target: -1 lun: -1
Warning: Using badly designed ATAPI via /dev/hd* interface.
Error trying to open /dev/hda exclusively (Device or resource busy)... retrying in 1 second.

and it repeats that last line till I kill it.

Now, I'm about to compile a new kernel to see if that'll help. If you guys have any other suggestions, I'll try them out.
Thanks.

DO NOT recompile your kernel. The errors above are normal. This is because the developer of cdrecord, Jorge Schilling, disagrees with the kernel maintainers about (no) scsi emulation in the kernel. So he puts those error messages in for the benefit of anyone who is running an IDE cd-rw drive rather than a SCSI cd-rw drive.

You should install cdrecord via apt-get rather than downloading individual debs. You now use proper device nomenclature for the dev= option instead of the ATAPI:luns method.
e.g instead of dev=ATAPI:0,0,0, you now use dev=/dev/cdrom

Instead of -scanbus, you use the -checkdrive option to do just that
eg. cdrecord -checkdrive

All the other options are still the same. So, if you are burning an ISO image to cd, do the following:
eg. sudo cdrecord -dao -vv speed=8 dev=/dev/cdrom driveropts=burnfree imagefile.iso

I really wish that they would make a point of saying those things when you install a new version. Is there a way of disabling the "error" warning?

I downloaded the cdrecord deb to make sure I was getting it from the debian servers and not from one of the other apt sources I have.

Anyways, thanks.
