Según en el wiki: http://gentoo-wiki.com/HOWTO_ATAPI_CD_Burning |
| 4 |
{wiki} |
| 5 |
To burn an iso with cdrecord you will have to find out the device id. This is used to identify your burner on the scsi bus. Yes even |
| 6 |
for ATAPI drives you will need the device id. Find it by issueing the following command |
| 7 |
|
| 8 |
cdrecord dev=ATAPI -scanbus |
| 9 |
|
| 10 |
It will give out put like below |

Notice the 3 numbers seperated by comma's, this is the device id that should be used for cdrecord. Mine is 0,0,0 but yours could be |
| 31 |
different so you need to replace it below with your device id. |
| 32 |
|
| 33 |
Some people will advice to use dev=/dev/hdc but this is unsupported and might not work. It might work for you but it is wrong. |
| 34 |
{/wiki} |
| 35 |
|
| 36 |
Es decir, que se debe usar dev=ATAPI. |
| 37 |
Especial atención al último párrafo, que dice que aunque funciona no es correcto. |
| 38 |
|
| 39 |
Según mensaje al terminar de compilar el cdrecord: |
| 40 |
{code} |
| 41 |
* The command line option 'dev=/dev/hdX' (X is the name of your drive) |
| 42 |
* should be used for IDE CD writers. And make sure that the permissions |
| 43 |
* on this device are set properly and your user is in the correct group. |
| 44 |
{/code} |
| 45 |
|
| 46 |
Por supuesto, sólo me funciona si uso la última recomendación. |
| 47 |
|
| 48 |
Pero resulta que cuando voy a grabar un iso: |
| 49 |
{code} |
| 50 |
# cdrecord dev=/dev/hdc:1,0,0 kororaa-xgl-livecd-0.2.iso |
| 51 |
cdrecord: No write mode specified. |
| 52 |
cdrecord: Asuming -tao mode. |
| 53 |
cdrecord: Future versions of cdrecord may have different drive dependent defaults. |
| 54 |

| 58 |
Warning: Open by 'devname' is unintentional and not supported. |
| 59 |
{/code} |
| 60 |
|
| 61 |
Y se me queda colgado. |
| 62 |
Si intento hacerlo con el ATAPI peor todavía: |
| 63 |
{code} |
| 64 |
# cdrecord dev=ATAPI:1,0,0 kororaa-xgl-livecd-0.2.iso |
| 65 |
cdrecord: No write mode specified. |
| 66 |
cdrecord: Asuming -tao mode. |
| 67 |

| 78 |
{/code} |
| 79 |
|
| 80 |
Si pruebo con gnombaker, por ejemplo, después de mucho rato aparentemente colga, aparece lo siguiente: |
| 81 |
{code} |
| 82 |
cdrecord: No write mode specified. |
| 83 |
cdrecord: Asuming -tao mode. |
| 84 |
cdrecord: Future versions of cdrecord may have different drive dependent defaults. |
| 85 |

| 86 |

| 87 |
cdrecord: WARNING: This causes a high risk for buffer underruns. |
| 88 |
cdrecord: Operation not permitted. WARNING: Cannot set RR-scheduler |
| 89 |
cdrecord: Permission denied. WARNING: Cannot set priority using setpriority(). |
| 90 |
cdrecord: WARNING: This causes a high risk for buffer underruns. |
| 91 |

| 92 |

| 93 |

| 94 |
Warning: Open by 'devname' is unintentional and not supported. |
| 95 |
{/code} |
| 96 |
|
| 97 |
Y no sale nada ni en los logs, ni en dmesg, ni en ningún lado. |
| 98 |
|

La verdad es que siempre me a parecido uno de los puntos flacos de linux, la grabación de cds. |
| 100 |
|
| 101 |
Esto es un cachondeo! :-D |
| 102 |
|
| 103 |
Muchas gracias de antemano. |
| 104 |
|
| 105 |
PD. Como podéis imaginar, he probado también con lo programas que hacen más fácil las cuestiones de grabar un puñetero CD, con |
| 106 |
resultados negativos siempre: gnomebaker (se queda colgado), menú contextual "Grabar en disco ..." (idem. que gnombaker), etc.... |
| 107 |
PD. La versión del susodicho: |
| 108 |
# cdrecord --version |
