这是一块新硬盘,但看起来读取错误率太高了。它高于阈值,但不确定这是否是新硬盘的正常现象。我应该申请更换吗?

这里重要的是,我们面对的是希捷.以下内容不适用于其他品牌!
Seagate 是少数能够解释 Seagate 硬盘的 SMART 含义的制造商之一:http://t1.daumcdn.net/brunch/service/user/axm/file/zRYOdwPu3OMoKYmBOby1fEEQEbU.pdf
3.1 Attribute ID 1: Raw Error Rate
Normalized Raw Error Rate = 10 * log10(NumberOfSectorsTransferredToOrFromHost * 512 * 8 /
(Number of sectors requiring retries))
Where the factor of 512*8 is to convert from sectors to bits. The attribute value is only
computed when the number of bits in the "transferred bits" count is in the range 1010 to 1012
.
The counts are cleared when Number Of Bits Transferred To Or From Host > 1012.
“Number of sectors requiring retries” does not count free retry or hidden retry.
Normalized Raw Error Rate is evaluated to a number between 1 and 166.
Raw Usage
Raw [3 – 0] = Number of sector reads
Raw [6 - 4] = Number of read errors.
因此,SMART 属性的原始值占 48 位。Seagate 的寻道错误率属性由两部分组成 - 最高 4 个半字节中的 16 位寻道错误计数和最低 8 个半字节中的 32 位寻道计数。
所以 0x000005B7B605 -> 0000-05B7B605 => 没有读取错误,读取 95925765。
如果你愿意,你可以使用这个在线表格它为你计算属性:
