Hola a Todos espero que se encuentren muy bien.
Les comento.
Tengo un detalle con lenny, el problema radica en que es muy lento para escribir, demasiado, esto pasa al grabar un DVD, al Grabar Un Pendrive o al copiar al disco desde otra partición. no se por que sera, lo comenze a notar al grabar DVD se demora casi una hora, con Brasero. :S , la verdad es que no lo habia notado hasta que me puse a grabar DVD, y pasar info a un pendrive.
Es un Portatil HP Pavilion DV2925LA.

el hdparm tira esto , mas aya no se que deba hacer...

despues ejecuto para medir la copia

scorpio:/home/faravena# hdparm -Tt /dev/sda

/dev/sda:
Timing cached reads: 2014 MB in 2.00 seconds = 1006.92 MB/sec
Timing buffered disk reads: 162 MB in 3.00 seconds = 53.92 MB/sec

y de hay no se que mas tengo que hacer, no se tampoco si los datos son correctos y si esto tiene o no que ver con la grabacion de DVD :S aver si me echan una mano.

¿Has probado hacerlo con K3b? Para comparar digo.
