Z FAQ dołączonego do xcdroast oraz własnego doświadczenia:

That new ATAPI mode is enabled by default in X-CD-Roast on linux.
It requires a kernel 2.4.x and is able to access ATAPI devices directly
through the IDE driver, without the help of SCSI emulation.
However, that mode is still experimental and causes some problems.
Using a CD writer in that mode is not recommended - please use always
SCSI emulation here. The ATAPI mode on a writer will cause great delays
in all X-CD-Roast operations, because communication with a device takes
much more time. You will also notice a lot of driver errors in your
system log files. This seems to be normal.
                                                                                 
You can tell X-CD-Roast to ignore the ATAPI mode when you start it with 
the
"-a" option.
                                                                                 
There is also no DMA transfer supported at all though the ATAPI 
interface.
                                                                                 
On some not correctly installed machines X-CD-Roast will find your 
devices
both via SCSI emulation and via ATAPI - they are displayed double in the
setup. Things could work nevertheless, but use the scsi-emulated devices
only then. (The devices without the "ATAPI:"-marking)
