Hi !

I have a problem, my DVD-burner Toshiba SD-R5002 doen't burn DVDs. I tried using k3b, burning CDs works, but burning DVDs does not. When I start growisofs from command line, I get this error:

Executing 'mkisofs a/ | builtin_dd of=/dev/scd1 obs=32k seek=0'
/dev/scd1: "Current Write Speed" is 1.0x1385KBps.
:-! "COMMAND SEQUENCE ERROR"@LBA=0h. Is media being read?
:-! the LUN appears to be stuck at 0h, retrying in 5 secs...
:-! "COMMAND SEQUENCE ERROR"@LBA=0h. Is media being read?

This keeps on repeating every 5 seconds, until I press CTRL-C. The common answer to this is to make sure that the DVD-burner isn't used otherwise, for example by an automounter. I don't think this is the case, because:

- I have a clean Knoppix-HD-install (Knoppix 3.3)
- Burning DVDs also doesn't work if I boot from CD (from my DVD-Reader of course .
- cdrecord works without problems

Does anybody have an idea what's going wrong ?
