Salve, ho un piccolo dubbio sul nuovo pc che ho acquistato da poco.
In particolare, un Dell XPS 1330. I dati sul disco rigido (da smartctl) sono:

Questo quanto ho ottenuto da un controllo recente, dopo un long test:

I dubbi sono due:

  • Il parametro Load_Cycle_Count cresce in modo abbastanza vertiginoso a meno di impostare la modalità di risparmio tramite hddparm al valore 254 o 255, cioè di fatto inibire tale modalità
  • I parametri UDMA_CRC_Error_Count e Multi_Zone_Error_Rate crescono senza sosta e vertiginosamente

Il dubbio che ho è se questo disco sia destinato a prematura morte o meno. Infatti a detta dei risultati del test non ci sono stati errori di sorta, eppure questi parametri sembrano indicare u ndecadimento costante econtinuativo del tutto.

Qualcuno di voi ha qualche consiglio o idea in merito?
A parte backup regolari non posso fare molto, aspettando solo la sua dolce e lieta fine...

Grazie

verifica la connessione, non mi pare che abbia nulla di anomalo a parte errori continui nel flusso dati.
Lo spin down per me serve solo sui portatili per far durare di più la batteria ma accorcia la vita dei dischi, però è una opinione e se ne è già discusso un bel pò.

per quanto riguarda la connessione non ci sono problemi, sono proprio quegli errori continui nel flusso dati che mi preoccupavano. o meglio, più che preoccupato sono perplesso perché mi sembra strano che avvenagno con tale frequenza e continuità!!
sullo spin down premetto che è un portatile, effettivamente, l'unica pecca è che a meno di non inibire le politiche di risparmio energetico del disco questo mette a riposo la testina e la risveglia con continuità, indipendentemente da quel che gli si dica di fare tramite software o configurazioni apposite... 'sto fetente!! :-D

mi cerco qualche discussione sullo spin down, và... ;-)

La saga continua, oggi per curiosità ho ridato una controllatina ed ecco il risultato:

Non male il load_cycle_count esploso (questo disco lo danno vitale fino a 600000, siamo giusto un po' oltre in soli 10000 e spiccoli di power_on)... che dite, mi devo preoccupare? Inizio anche a dubitare della bontà dei dati restituiti da smartctl, poiché se uno fa il rapporto load_cycle_count su ore di attività viene una cosa fisicamente impossibile......................... :?:

HELP!

[EDIT]: ora che ci penso, in un mese come posso aver tenuto acceso il disco ben 10389 ore???? 8O

In neanche dieci giorni avrei tenuto il pc acceso quasi duemila ore e raddoppiato i load_cycle_count!! :-D
Si, a questo punto penso che il problema sia dei tools e non del disco... ;-)[/profile]
