Accessing Your CD-R Drive
Linux supports recording on IDE ATAPI CD-R drives through a special driver called
ide-scsi. Most Linux distributions also include this driver in the kernel. If your sys-
tem does not have the driver, you will need to load the driver module (installing it if
needed), or possibly recompile your kernel.
The ide-scsi driver emulates a SCSI device for software that is designed just for SCSI
devices. Your IDE ATAPI CD drive and DVD drive will appear as if they are SCSI
devices when the ide-scsi driver is active.
The following command will list the SCSI devices on your system, so you can locate
the emulated SCSI device number for your CD-R drive. It may list other devices as
well, including any real SCSI devices if your computer actually has them. Run the
command as root:
# cdrecord -scanbus
The output might look similar to this:
