<div dir="ltr">Hola amigos, Recorro a su ayuda y buena voluntad para solucionar el siguiente problema: Como mi hijo me rompio por segunda vez la grabadora de DVD procedi a comprar una tercera, sinceramente no chequee en algun site la compatibilidad de la misma con Ubuntu (si, ya se, muy mal hecho) pero como mis experiencias anteriores fueron buenas compre algo que considere standard sin mirar demasiado. Ya busque en Google y encontre que hay gente que la tiene andando con Ubuntu sin problemas (no puede encontrar nada que hable de Hardy especificamente) El problema es el siguiente: Inserto los CD / DVD y me permite ver el contenido pero no abrir y/o copiar los archivos. La respuesta ante el intento de copiar archivos es el siguiente: Hubo un error al copiar el archivo en /home/miguel/Escritorio - Error al leer del archivo: Error de entrada/salida Estoy usando Hardy Heron / Kernel 2.6.24-19, se pueden descartar problemas de Hard ya que en otros sistemas operativos anda correctamente La salida del comando lshw es:  *-cdrom:0                 description: DVD-RAM writer                 product: DVD RW AD-7190A                 vendor: Optiarc                 physical id: 2                 bus info: scsi@3:0.0.0                 logical name: /dev/cdrom                 logical name: /dev/dvd                 logical name: /dev/scd0                 logical name: /dev/sr0                 version: 1.05                 capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram                 configuration: ansiversion=5 status=ready La salida del comando dmesg es: [ 1169.859284] end_request: I/O error, dev sr0, sector 108 [ 1169.862998] sr 3:0:0:0: [sr0] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE,SUGGEST_OK [ 1169.863002] sr 3:0:0:0: [sr0] Sense Key : Hardware Error [current] [ 1169.863005] sr 3:0:0:0: [sr0] Add.
