J'ai une voiture vieille d'un an qui me pose des problèmes. La copie des données vers celui-ci échoue après environ 8 à 10 Go de transferts. Il change spontanément en «lecture seule». Il est correctement formaté ext4, je suis le propriétaire. La recherche en ligne, il semble que ce soit le symptôme d'une panne de disque.
Comment puis-je confirmer cela, car les tests SMART indiquent le contraire?
J'ai fait l'évidence comme vérifier l'utilitaire de disque et j'ai exécuté le test SMART étendu. Tous les résultats de Disk Utility reviennent parfaitement. Le taux d'erreur de lecture et les secteurs réaffectés affichent zéro.
Je suppose que ce disque est mauvais et SMART ne le détecte pas, bien que je ne comprenne pas pourquoi. Je voudrais confirmer quel est le problème.
Je n'ai aucun problème avec les autres disques de la machine.

Le dernier mais non le moindre est la capture d'écran en lecture / écriture, c'est nouveau. Il restait assez cohérent pendant la durée du test.
EDIT- Lorsque j'ai allumé ce matin, le lecteur était passé de / dev / sda à / dev / sdc, étrange. Je suis certain que cela ne s'est jamais produit auparavant et je suis certain que c'était / dev / sda. J'ai échangé des câbles SATA avec un bon et connu ce même échec à environ 10 Go de transferts. Je n'ai pas encore changé les ports SATA, je vais essayer ça ensuite. (Edit # 2, c'était le port SATA, le changer a résolu le problème. Signaler cela comme trop localisé.)
