使用哈希而不是登录密码对是否安全？
我买了 HDD Toshiba MG 12tb MG07ACA12TE 在打开的塑料盒中。
在我的硬盘上，我看到生产日期：05-15-2019
当我在东芝网站上查看我的序列号时，我看到了过期日期：2021/06/17
这是我的智能测试
G-Sense_Error_Rate — 1
Disk_Shift — 6
我知道有人掉了硬盘。
这很关键吗？

我有这样的设置
C:\Windows\system32>smartctl -l scterc /dev/sda
SCT Error Recovery Control:

我需要设置超时吗？
smartctl -l scterc,70,70 /dev/sda
