K3B cd recording software not working

[abrand888]

I saved many files and wanted to burn them with the built in recording software and it failswwhether I used a cd-rw or cdr disc. Is this a problem in Knoppix 3.8.1 ?

Thanks

I am having the same problem with Knoppix 3.8.2. I have tried several variations of settings with no success.

The software lists during the "record phase" (these are not verbatim):

i Size 5600 blocks (only trying to record a small amount)
i Using cdrecord 2.1.1a01
i Starting tao @ 8x (mine is an 8x recorder)
X cdrecord returned an unknown error (code 12)
X cannot allocate memory
X Please send me an e-mail ...

Occasionally, with some setting change, I get an error about "Probabbly a buffer underrun, choose a lower speed". Lower speeds do not help, and even with no additional changes, the original error returns.

Any suggestions. This utility would be very useful to recover data from an unbootable Windows system!

I had the same problem and found out what was up. The Linux kernel v2.6 doesn't need the old SCSI emulation cdrecord used to use. For instance, if you want to see what your CD device is, use:

cdrecord dev=ATAPI: -scanbus

Then use that device to work with your CDR or CDRW. For mine, it found my CDRW on ATAPI:0,0,0 and to quickly BLANK a CDRW I used this:

cdrecord dev=ATAPIi:0,0,0 blank=fast

Another thing you can do is to put the following lines to your /etc/default/cdrecord file( my CDRW is on dev 0,0,0 ):

CDR_DEVICE=cdrw
# name = ATAPI:yourdev speed(-1 for default) fifosize(-1 for default )
cdrw=ATAPI:0,0,0 24 30m


Now, you won't have to specify the device each time you use cdrecord, it'll use the device specified in your /etc/default/cdrecord file.

note: K3b still doesn't work unless you start it from a commandline as ROOT. I tried "dpkg-reconfigure cdrecord" to set the SUID bit on cdrecord but that still didn't work.

Thanks. The above worked for me using cdrecord. For example, I was able to burn a copy of the /home/knoppix directory to a CD with this command pipeline:
mkisofs /home/knoppix | sudo cdrecord -

Unfortunately, same here. I too was unable to get cdrecord to work as user Knoppix and had to use sudo even though cdrecord is SUID. Is there a way for k3b to use "sudo cdrecord" instead of just cdrecord?
