CDROM Copy

[TheCotMan]

i am unable to copy any CD with any GUI program like k3b etc. I get an error no media found in the CDROM. THe CD is not copy protected. My DVD writer works fine and if i run md5sum /dev/hdc on it i get the correct checksum. However when i do the same with the CDROM, i get an input/output error. The CDROM reads data and plays audio CDs no problem. "cdrecord -scanbus" shows up both the drives.

My udev seems fine with all the right rules.

Your best best would be a Linux User Group, or a mailing list that supports this software.

Common problems with CD-Writing software in Linux:
1) Symlink for /dev/cdrom does not point to your actual CD-ROM drive
2) Permissions for the CD-ROM device in /dev allow for read access, but not read/write for the user trying to read/write the CD. (What does /dev/cdrom point to?)
3) An older issue for CD writing software was a need to have your system treat an IDE style drive as a SCSI drive and enable CONFIG_BLK_DEV_IDESCSI support in a kernel (aka "SCSI emulation support") and then passing a kernel option at boot (via lilo.conf with an append="" or from lilo at boot, or maybe with grub) like this: "hdb=scsi" for your ide device. This may no longer be necessary with newer kernels and newer burning software, but is worth checking out.

I would suggest this:
First, locate a simple data CD.
# cat /dev/cdrom >> /tmp/test.iso
then tell cdrecord to burn that iso image to a new cd.

If that works, then the problem you face is one of configuration of your GUI software.

With the above list of suggestions for things to check you have a long list of search terms to apply to google searches.

HTH and good luck.

Hi

I hope this is not way OT for the Defcon forum.

I am having a problem on a Mandrake 10.1 machine where i am unable to copy any CD with any GUI program like k3b etc. I get an error no media found in the CDROM. THe CD is not copy protected. My DVD writer works fine and if i run md5sum /dev/hdc on it i get the correct checksum. However when i do the same with the CDROM, i get an input/output error. The CDROM reads data and plays audio CDs no problem. "cdrecord -scanbus" shows up both the drives.

My udev seems fine with all the right rules.

If i put in a Knoppix CD all works fine, so the BIOS settings and hardware setup must be fine.

Thought i would ask this question here as all my other channels have been exhausted.
