Problems with cdrtool. Included dmesg output.

Hello, I wonder if anyone can help me. I desperately want to use packet-cd, but I can't seem to get it to work. When I use cdrwtool I get the following error from cdrwtool -d /dev/scd0 -q wait_cmd: Input/output error Command failed: 04 17 00 00 00 00 00 00 00 00 00 00 - sense 03.0c.00 format disc: Illegal seek I used it on my usb cdrw and my internal/ide cdrw drive. Here's my dmesg output. Please. I hope someone can help. -Leo
