Analyse disque dur

Bonjour,
J’entreprends le dépoussierage de plusieurs disques durs : pouvez-vous m’aider à me confirmer qu’ils sont bons pour la casse ou non ?

Voici un premier rapport. J’ai lu que si le ‹ remaining › est à 00% après un self-test alors le disque n’est pas mort. Confirmez-vous ?

Selective self-test flags (0x0):
  After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.

Non, ça veut juste dire que le dernier n’a pas eu d’erreur, ça ne veut rien dire de plus.
Si tu veux avoir des données plus récente, n’hésite pas à lancer un auto-test.

Bonsoir
Par contre ces données ne sont pas un bon signe par rapport à la santé du disque

5 Reallocated_Sector_Ct    
...
197 Current_Pending_Sector

5 et 197 ne sont pas les valeurs, mais les identifiants, les valeurs sont respectivement 0 et 0, ce qui est très bien, surtout pour un disque qui n’a tourné que 4283 heures (modulo 65536).

Oui tout à fait,
je me suis trompé de colonne entre VALUE et RAW_VALUE

ID# ATTRIBUTE_NAME          FLAG     VALUE WORST THRESH TYPE      UPDATED  WHEN_FAILED RAW_VALUE

Autant pour moi :wink: Désolé
