Synology NAS：坏扇区数从 3856 降至 0

Question

我收到了如下的每月磁盘健康报告：

Dear user,

The following is your monthly report regarding the health of disks on
DiskStation. You can also check the health of individual disks at
Storage Manager > HDD/SSD > Health Info.


Disk 1:
        Disk Reconnection Count 2
        Bad Sector Count 3856
        Disk Re-identification Count 0

Disk 2:
        Disk Reconnection Count 0
        Bad Sector Count 0
        Disk Re-identification Count 0


Sincerely, Synology DiskStation

从那时起我每周都会制定一个任务计划。

现在我得到：

Disk 1:
        Disk Reconnection Count 0
        Bad Sector Count 0
        Disk Re-identification Count 0

Disk 2:
        Disk Reconnection Count 0
        Bad Sector Count 0
        Disk Re-identification Count 0

这怎么可能？
