1) Use ATA, not ATAPI. ATAPI uses a very old API with no DMA support.
2) Wenn using ATA, just do a cdrecord dev=ATA -scanbus and you get
something like:
scsibus1:
1,0,0 100) 'HL-DT-ST' 'CD-RW GCE-8481B ' '1.05' Removable CD-ROM
1,1,0 101) 'PIONEER ' 'DVD-RW DVR-106D' '1.08' Removable CD-ROM
1,2,0 102) *
[...]
Now, just address the drive using the numerical bus ID:
cdrecord dev=ATA:1,1,0 -checkdrive

Well, there still are tons of warnings, but I'm not
opening the device by devname, so that one disappears.
