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: http://www.fokus.gmd.de/research/cc/glone/employees/joerg.schilling/private/ cdrecord.html ># cdrecord -scanbus >Cdrecord release 1.6.1 Copyright (C) 1995-1998 J=81=F6rg Schilling >cdrecord: No such file or directory.

Issue the following command: ln -s /dev/rcd0.ctl /dev/scgx >Device seems to be: Generic mmc CD-R. >Using generic SCSI-3/mmc CD-R driver (mmc_cdr). 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. --- Stefano Riva Software Engineer - Systems Administrator Informazioni Editoriali I.E.
