Como puedes ver using_dma = 0 (off) haz un hdparm -d 1 /dev/hda para activarlo
I si miro el rendimiento: /dev/hda: Timing cached reads: 1780 MB in 2.00 seconds = 888.80 MB/sec Timing buffered disk reads: 8 MB in 3.85 seconds = 2.08 MB/sec
Prueba de nuevo el hdparm -tT /dev/hda y veras que cambio en la velocidad de lectura
Un saludo
