Vérification d'éventuels problèmes de disque dur

Vérification du disque dur

Les disques durs disposent d'un outil incorporé de surveillance des défauts appelé SMART (Self-Monitoring, Analysis, and Reporting Technology), qui explore en permanence le disque dur à la recherche de problèmes potentiels. SMART vous avertira si le disque est sur le point de tomber en panne, vous permettant ainsi d'éviter des pertes de données importantes.

Although SMART runs automatically, you can also check your disk’s health by running the Disks application:

Check your disk’s health using the Disks application

  1. Open Disks from the Desktop.

  2. Choisissez le disque dans la liste des périphériques de stockage. Les informations sur le disque et son état s'affichent.

  3. Click the menu button and select SMART Data & Self-Tests…. The Overall Assessment should say “Disk is OK”.

  4. Consultez les informations supplémentaires dans Attributs SMART, ou cliquez sur Démarrer l'auto-test.

What if the disk isn’t healthy?

Even if the Overall Assessment indicates that the disk isn’t healthy, there may be no cause for alarm. However, it’s better to be prepared with a backup to prevent data loss.

If the status says “Pre-fail”, the disk is still reasonably healthy but signs of wear have been detected which mean it might fail in the near future. If your hard disk (or computer) is a few years old, you are likely to see this message on at least some of the health checks. You should backup your important files regularly and check the disk status periodically to see if it gets worse.

S'il y a aggravation, il vaut mieux emporter l'ordinateur ou le disque dur chez un professionnel pour un diagnostic complet ou une réparation.
