Hi all, I've checked: CDRW is insearted, Properly formated, i have checked it on Windows and tried to mount as udf disk on Linux. It looks udf file system. pktcdvd module is loaded. I can mount this CDRW as udf to read/write. And copy file to disk passed. But if i try to umount i have got a error, after that CD looks like not formated. What is the problem. May be Tekram controller could not work with udf system? Kirill

You have one of follows:

- disk is not inserted in CDRW drive - not properly formatted UDF disk (check disk with chkudf utility) - not loaded pktcdvd module (to list dynamic loaded modules rub lsmod) - bad record in /etc/fstab
