[Tech] hard disk lento

Ciao a tutti.
Sto indagando sulla lentezza del mio disco fisso.
Per chiarezza questa č la configurazione del mio sistema:
Slackware 12 con kernel di default (kernel-2.6.21.5-smp);
hd SAMSUNG MP0804H
File Systems: ReiserFS
Ho verificato la presenza del modulo ata_generic e ho fatto un test con
smartctl ottenendo quanto segue.
Non riesco a capire le indicazioni di smartctl, potete aiutarmi a
decifrarle, cosė che io possa capire cosa cercare su internet per
tentare di risolvere il problema?
Grazie, Valerio

SMART Error Log Version: 1
ATA Error Count: 49672 (device log contains only the most recent five
errors) CR = Command Register [HEX]
FR = Features Register [HEX]
SC = Sector Count Register [HEX]
SN = Sector Number Register [HEX]
CL = Cylinder Low Register [HEX]
CH = Cylinder High Register [HEX]
DH = Device/Head Register [HEX]

Powered_Up_Time is measured from power on, and printed as
DDd+hh:mm:SS.sss where DD=days, hh=hours, mm=minutes,
SS=sec, and sss=millisec. It "wraps" after 49.710 days.
Error 49672 occurred at disk power-on lifetime: 3588 hours (149 days +
12 hours) When the command that caused the error occurred, the device
was active or idle.
After command completion occurred, registers were:
