我有一个 ATA 错误计数增加的硬盘（Western Digital），我在不同论坛上搜索了不同的帖子，其中一些说硬盘坏了，其他人说连接（SATA 电缆）有问题。
智能测试本身没有显示问题——原始值（据我所知）很好。
有任何想法吗？我也不确定“Offline_uncorrectable”和 Multi_Zone_Error_Rate 中的最差值 253 可能意味着什么。由于原始值为 0，因此不应该有坏道。

SS=sec, and sss=millisec. It "wraps" after 49.710 days.
Error 40878 occurred at disk power-on lifetime: 2054 hours (85 days + 14 hours)
When the command that caused the error occurred, the device was active or idle.
After command completion occurred, registers were:
