Does anyone have a suggestion? When you install ide-scsi emulation, your CD-ROM drive(s) and writers show up as SCSI devices, not their ordinary ide devices. So their names change. You need to edit /etc/fstab and change any entries that say "hdx" (where x is your old CD-ROM drive) to "scdx" (where x would be 0 for the first CD drive detected, 1 for the second, etc). You will also need to change the link in /dev. if you run ls -l /dev/cdrom, you will see that /dev/cdrom probably points to your former ide device name. > This is the first time I have posted to this discussion group.

If I were you, I'd use xcdroast. It is a graphical front end that uses cdrecord to do the acutal work, but is more user friendly than many windows CD burning programs. > Thanks for your help...and for your patience in reading through this. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- What the president of the Motion Picture Association of America says about taking away your constitutional rights: "I'm rather jubilant now.
