检查磁盘错误

检查硬盘

硬盘中含有一个内置健康检查工具，叫做作 SMART，该工具可以不断检查磁盘的潜在问题。如果磁盘即将发生故障，SMART 还会提出警告，帮助您避免重要数据的丢失。

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. Select the disk you want to check from the list of storage devices on the left. Information and status of the disk will be shown.

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

  4. See more information under SMART Attributes, or click the Start Self-test button to run a self-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.

如果磁盘持续老化，您最好将计算机/硬盘交由专业人员进行进一步诊断或维修。
