SMART正在说明我服务器硬盘上的一个待处理扇区.我已经阅读了许多文章,建议使用hdparm“轻松”强制磁盘重新定位坏扇区,但我找不到正确的方法来使用它.
我的“smartctl”中的一些信息：
Error 95 occurred at disk power-on lifetime: 20184 hours (841 days + 0 hours)
When the command that caused the error occurred,the device was active or idle.
After command completion occurred,registers were:
ER ST SC SN CL CH DH
-- -- -- -- -- -- --
40 51 00 d7 55 dd 02 Error: UNC at LBA = 0x02dd55d7 = 48059863
Commands leading to the command that caused the error were:
CR FR SC SN CL CH DH DC Powered_Up_Time Command/Feature_Name

有了“糟糕的LBA”(48059863),我该如何使用hdparm？参数“–read-sector”和“–write-sector”应该具有哪种类型的地址？
如果我发出命令hdparm –read-sector 48095863 / dev / sda,它会读取并转储数据.如果这个命令是正确的,我应该期待一个I / O错误,对吗？
相反,它转储数据：
$./hdparm --read-sector 48059863 /dev/sda
/dev/sda:
reading sector 48059863: succeeded
