I did it just one time, months ago. I'm almost sure it worked for me
without other options.

Maybe your version of cdrecord (1.6.1) is different... I'm using 1.6a12.
I put the driver name after the "driver=3D" option, as I said in my previous
message.
Thereafter I'll still assume the syntax is the same, anyway you may find
more info in the cdrecord's home page:

This is a problem.

This isn't a problem.

I said capital X is the unit number. Keep the other x unchanged. Issue
the following command:
ln -s /dev/rcd0.ctl /dev/scgx

Are you sure this is the right driver? Check with driver=3Dhelp, search th=
e
cdrecord's home page, search the newsgroups with Altavista. My Traxdata is
recognized as Generic CD-R, but it needs driver=3Dteac_cdr50 to work.
