此硬盘没有任何损坏迹象。

Num  Test_Description    Status                  Remaining  LifeTime(hours)  LBA_of_first_error
# 1  Extended offline    Completed without error       00%      1856         -

告诉你它在 1856 天时做了一次延长离线测试，并且无错误地完成了。剩下的 00% 意味着测试已经结束。

这

5 Reallocated_Sector_Ct   0x0033   200   200   140    Pre-fail  Always       -       0

显示磁盘上没有坏扇区，因此无需重新分配。其他读数似乎也很好。

如果你想让自己冷静下来，做一个长时间的测试

smartctl --test=long /dev/sda

然后再次检查读数，如果运行没有错误，则一切正常。

顺便说一句，每天进行短测试、每周进行长测试是一个好习惯。
