Caracteristicas:
hdparm -gi /dev/hda
/dev/hda:
geometry = 16383/255/63, sectors = 80026361856, start = 0

Configuracion:
dev/hda:
multcount = 16 (on)
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 0 (off)
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
