HDD vypinanie a zapinanie
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.

hmmm. to ty si aktivoval laptop mode alebo je to vypinanie disku zalezitostou vadneho firmware ako som to zazil ja?
... inak pozeral som datasheet k mojmu disku a konkretne tam bola uvedena aj hodnota Load_Cycle_Count. Maximum je 600.000 a moj disk ukazuje po cca pol roku pouzivania nejakych 70.000. Hladal som v datasheete aj polozku Start_Stop_Count, ale tu som tam nenasiel. Neviem, ci to ma nieco spolocne s polozkou Start_Stop_Count, ale cislo je take podobne.
Ako je nastavena sluzba hdparm, ak ju teda za sluzbu mozeme povazovat?
skusal som aj uplne vypnutie, teda nastavit parameter 254 a teplota mi stupla na nejakych 51°C a tam aj zostala. Len teraz neviem, ci je to dobry napad uplne vypnut ten spin-down, ci sa nebude viacej ten disk prehrievat, alebo ci to nebude nejako skodit otrasom, ked cestujem napr. vo vlaku.
Inak, spindown nie je na znizenie teploty aj ked je to jeho vedlajsim efektom. Rovnako, ako pri vypnuti celeho pocitaca.
Ale inac si to vies nastavit hdparm -S 12 /dev/sdx
-S Put the drive into idle (low-power) mode, and also set the standby (spindown) timeout for the drive. This timeout value is used by the drive to determine how long to wait (with no disk activity) before turning off the spindle motor to save power. Under such circumstances, the drive may take as long as 30 seconds to respond to a subsequent disk access, though most drives are much quicker. The encoding of the timeout value is somewhat peculiar. A value of zero means "timeouts are disabled": the device will not automatically enter standby mode. Values from 1 to 240 specify multiples of 5 seconds, yielding timeouts from 5 seconds to 20 minutes. Values from 241 to 251 specify from 1 to 11 units of 30 minutes, yielding timeouts from 30 minutes to 5.5 hours. A value of 252 signifies a timeout of 21 minutes. A value of 253 sets a vendor defined timeout period between 8 and 12 hours, and the value 254 is reserved. 255 is interpreted as 21 minutes plus 15 seconds. Note that some older drives may have very different interpretations of these values.
Preto su tam take vysoke cisla pri vypinani a zapinani.
Ale, myslim ze tato diskusia stratila zmysel uz davno.
PS.: ja spindown nepouzivam nakolko sa nejedna o riesenie ale o barlu.
