Hola saben tengo un problemon

He estado leyendo y verificando que sucede con mi pc que tiene linux, esta empieza a arrojar una serie de errores.

De lo poco que he leido y probado se supone que es un problema de HD, algunos usan el concepto de que HD se esta muriendo? bueno no enteder del todo el termino aun...

Dejenme les cuento he estado probando con el hdparm y e testeado mi linux, estos son los datos:

#dmesg | grep hda

y a partir de esta linea hda: timeout waiting for DMA, comienza el errror

He intentado modificar esto con hdparm tratando de activar el DMA

Esto es para optimizar (sugerencia de un how)

#hdparm -X66 -u1 -m16 -c3 -W1 /dev/hda

#hdparm /dev/hda

/dev/hda:
multcount = 16 (on)
I/O support = 3 (32-bit w/sync)
unmaskirq = 1 (on)
using_dma = 0 (off)
keepsettings = 0 (off)
nowerr = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 2586/240/63, sectors = 39102336, start = 0
busstate = 1 (on)

#hdparm -i /dev/hda

/dev/hda:

Model=ST320413A, FwRev=3.57, SerialNo=7ED1BCSF
Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs RotSpdTol>.5% }
RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=0
BuffType=unknown, BuffSize=1024kB, MaxMultSect=16, MultSect=16
CurCHS=17475/15/63, CurSects=16513875, LBA=yes, LBAsects=39102336
IORDY=on/off, tPIO={min:240,w/IORDY:120}, tDMA={min:120,rec:120}
PIO modes: pio0 pio1 pio2 pio3 pio4
DMA modes: mdma0 mdma1 mdma2 udma0 udma1 *udma2
AdvancedPM=no WriteCache=enabled
Drive Supports : Reserved : ATA-1 ATA-2 ATA-3 ATA-4 ATA-5

el asunto es cuando trato de activar el DMA ya que esta apagado: using_dma = 0 (off)


#hdparm -X66 -d1 -u1 -m16 -c3 -W1 /dev/hda

trata de activar todo y se detiene un poco en using_dma tratando de activarlo y manda errores y me añade una nueva linea de error cuando veo los hda:

#dmesg | grep hda {el listado del principio mas un nuevo error mas}

he provado activarlo por separado y en conjunto

#hdparm -d1 /dev/hda
#hdparm -X66 -d1 -u1 -m16 -c3 -W1 /dev/hda

y la unica forma de activarlo momentaneamente es:

#hdparm -c3 -d1 /dev/hda

lo activa pero despues de unos minutos manada mensajes de error y se desactiva todo.

el problema que tengo es con el HD (sino corrijanme plis) y especificamente con el DMA y tal ves le este pegando a mas cosas.

Que puedo hacer...


Espero me puedan ayudar, con sus aportaciones gracias....
