Titolo: ssd vertex 2 e tasso letture errate

Dopo qualche ora di funzionamento il parametro SMART denominato "Tasso 
letture errate" ( id 1 ) mostra valori molto alti.
 
una volta mostrava oltre 4.000.000
un'altra volta mostrava oltre 7.000.000
 
 
ad ogni reboot perï¿œ mostra 0
 
ï¿œ normale ?
 
ï¿œ il caldo ? noto che il notebook sta contribuendo al riscaldamento 
globale...
 
 
ps.
errori ECC non correggibili 1408
 
 
comprato da 3 anni ma il tempo di funzionamento dice solo 3 mesi ( ï¿œ 
falso... sta acceso almeno 8 ore al giorno da molti mesi )
 
 

 
 
Prova ad usare se non l'hai ancora fatto il tool Crystal Disk Info
 per i dati smart...ti dovrebbe dire anche i dati totali scritti
 sulle celle NAND sino ad ora.

uso linux mint ed ï¿œ incluso in MATE-desktop una utility denominata 
DISCHI ( mate ï¿œ bello ma cambiando i nomi ai programmi storici hanno 
fatto solo casino... gedit si chiama pluma ! )
 
 
 
il prog DISCHI ï¿œ fatto da redhat
 
 
qualcosa per linux ?

 falso... sta acceso almeno 8 ore al giorno da molti mesi )
 
non so se sia normale o meno, anch'io ne ho uno da 3 anni
e non ho fatto caso a questa anomalia (i valori sono a zero)
 
copia/incolla il report completo degli SMART (smartctl),
ma se il sistema funziona e non ci sono freeze o
disconnessioni dell'unita', non e' il caso di preoccuparsi
 
l'ideale sarebbe fare anche un bench con AS-SSD
o Crystal Disk Mark, ma sono sw per Windows
 
come prima verifica potresti sostituire il cavo SATA ,
successivamente aggiornare il firmware
ed effettuare un Secure Erase (previo backup)

 che mi dite del parametro 231 ?
 
i parametri SMART sono nella norma, tranne il
"Raw Read Error Rate" che ha quel comportamento
anomalo che descrivi, ed "ECC Uncorrect Error Count"
(stesso valore grezzo)
 
il parametro 231d "SSD Life Left" indica ancora il 100% di vita residua,
con 1,4TB di dati scritti (su un totale di 600TB teorici)
 
confermo le considerazioni fatte nell'altra risposta
