Bonjour,
Je rencontre un comportement assez étrange avec un WD red WD60EFRX. Le disque est affecté par des “Read Error” assez inhabituelle.
De mon expérience, un “bad sector” physique se révèle rapidement avec une simple commande de lecture et d’écriture qui abouti à un i/o error.
A l’opposé, le “Bad sector” logique se fixe facilement avec la commande dd en écriture.
Dans le cas de ce disque, une portion du disque retourne systématiquement des “read error”, j’arrive très bien a écrire sur les secteurs remontés en erreur, puis a les relire (commande dd iflag/oflag direct,write).
Cela ne résous malheureusement pas l’anomalie et le test smart suivant retourne toujours des read error.
Voici les attributs smart du disque ainsi que le type d’anomalie remonté dans mon syslog.

Étrangement un des test “short” est passé ?

Je pense que que ce disque a un vrai soucis qui ne peut être résolu de façon logique et necessite un rma.
Qu’en pensez vous ?
Merci.
