Ciao a tutti,
ho un Asus ZenBook UX31A, che monta al suo interno un SSD, che mi sta dando dei problemi:
a volte, in modo più o meno casuale, il PC crasha e, ai successivi riavvi, il suddetto disco non appare più nemmeno nel BIOS.
In seguito, lasciando "riposare un po' " l'hardware, il tutto torna in funzione.
Il disco ha, mi pare di ricordare, circa 5 anni ed è stato usato in modo abbastanza intensivo (non fosse altro perché è il disco principale del PC, con installato sopra il SO).
Inutile dire che ho copie di back-up di tutto.
Vorrei però capire che test effettuare per sapere se devo buttare il disco oppure se - non so, magari formattandolo - posso utilizzarlo nuovamente in modo relativamente sicuro. Faccio notare che il disco è montato all'interno del portatile per mezzo di un adattatore, perché questo Asus ha un connettore "strano" per l'SSD. Magari potrebbe essere anche quest'adattatore il problema, non saprei. Tuttavia vorrei capire.
Al momento ho usato smartctl (uso linux) e vi chiederei il favore di interpretare i risultati che ho ottenuto, perché, sinceramente, ho provato mo ho molti dubbi al riguardo.
Grazie mille
