Problemas com gravação de CD

[Fabricio Vaccari Constanski <fabriciovc@gmail.com>]

Possuo uma gravadora cuja o retorno do comando que a documantação
mandou eu digitar para kernel 2.6 é:

fabricio@servidor:/tmp$ cdrecord dev=ATA: -scanbus

NOTE: this version of cdrecord is an inofficial (modified) release of cdrecord
      and thus may have bugs that are not present in the original version.
      Please send bug reports and support requests to
<cdrtools@packages.debian.org>.
      The original author should not be bothered with problems of this version.

Só que não consigo gravar. O cdrecord diz

fabricio@servidor:/tmp$ cdrecord -v dev=ATA: speed=8 -data /tmp/cd.iso 
cdrecord: No write mode specified.
cdrecord: Asuming -tao mode.
cdrecord: Future versions of cdrecord may have different drive

TOC Type: 1 = CD-ROM
scsidev: 'ATA:'
devname: 'ATA'
scsibus: -1 target: -1 lun: -1
Warning: Using badly designed ATAPI via /dev/hd* interface.
Linux sg driver version: 3.5.27
Using libscg version 'schily-0.8'.
SCSI buffer size: 32768
atapi: -1
cdrecord: Cannot do inquiry for CD/DVD-Recorder.
cdrecord: Input/output error. test unit ready: scsi sendcmd: fatal error
CDB:  00 E0 00 00 00 00
cmd finished after 0.000s timeout 40s

e o K3B detecta mas não libera o botão BURN.

Em outras experiências, era só detectar a unidade com o comando
cdrecord -scanbus e mandar gravar com a linha acima comentada.

HELP!!!
