Dotaz: HDD vypinanie a zapinanie

Zdravim.

Pouzivam notebook Lenovo G550. Je tam pevny disk WD Scorpio Blue 320 GB SATA Hard Drives (WD3200BEVT). Neviem ako by som to popisal, ale mam pocit, ako keby sa disk kazdu chvilku vypinal, resp. zapinal. Napr. niekedy 2x, niekedy 3x za minutu sa disk akoby znovu rozbiehal. Toto sa deje normalne za chodu systemu. Pri praci to vyzera asi tak, ze ked napriklad pozeram film, tak pri tomto "nabiehani" sa film na 1-2 sekundy zasekne a po tomto case, ked uz disk bezi ako ma sa rozbehne aj film (toto nabiehanie je aj pocut, teda akoby sa zvysovali otacky + spominane zaseknutie systemu na 1-2 sekundy). Stava sa to v podstate pri kazdej praci. Idem otvorit Nautilus a ked sa disk zacne rozbiehat, tak sa vsetko na chvilku zasekne. Deje sa to ci uz pri napajani zo siete, alebo na bateriu. Notebook pouzivam v podstate kazdy den od Septembra roku 2009, cize cca nejakeho pol roka. V prilohe zasielam vypis S.M.A.R.T.-u. Ak by boli treba este nejake informacie, samozrejme ich poskytnem. Rad by som vedel, ci to je nejaka vada, alebo to tak ma byt, ci to disku skodi, alebo nie, ci to znizuje zivotnost, ci by nebolo lepsie to odstranit. V podstate teda by som rad ziskal nejake informacie o tomto "jave". OS pouzivam Debian Testing, Gnome 2.28.2, Kernel 2.6.32, teplota disku sa pohybuje v okoli 44°C.

Ahoj, neco podobnyho se mi taky stalo. Zkousel jsem ruzne menit dobu parkovani hlav, ale nefungovalo to (asi jsem na to sel spatne). Vim, ze je to hodne spatny reseni, ale napsal jsem skript, ktery se spusti hned pri startu systemu a "nuti disk k cinnosti":

#!/bin/bash

cd /tmp

while [ 1 ]; do
    POC=1
    while [ "$POC" -le 20 ]; do
	CAS=`date +%s`
	dd if=/dev/urandom of=/tmp/urandom$CAS bs=512 count=1 > /dev/null 2>&1
	sync
	POC=$((POC + 1))
	sleep 5
    done
    rm /tmp/urandom*
done

A je to teda to parkovanie hlav, ako spominas, alebo to je vaznejsi problem? Ako zistim aku mam nastavenu dobu parkovania hlav, resp. ako tu dobu zmenim? Je to dobre riesenie, obmedzit parkovanie hlav? V tejto oblasti nemam skoro ziadne znalosti.

Na ten vypis jsem nekoukal. Rikal jsi, ze se disk sam vypina, tak jsem napsal to, co mne pomohlo.

Kdesi na internetu jsem vyhrabal programek wdiddle.
