我刚刚购买了一台二手的 8TB Seagate Exos HD，虽然它运行正常，但引起我注意的是，它在启动时会发出非常奇怪的声音，这是我第一次购买 seagate hd，也是我第一次购买二手存储，使用较小的（2TB）WD hd 从未听到过如此奇怪的声音。
我用 Seatools 测试了磁盘，它通过了短期和长期测试。还检查了 HD Sentinel 和 Crystaldskinfo，似乎也不错，但我不太理解结果中列出的许多参数。

请帮我解读 SMART 报告。
答案1
我关心以下参数中的一些数字：命令超时、Ultra ATA CRC 错误、硬件 ECC 恢复、寻道错误率和原始读取错误率。
一些 Seagate RAW 值非常违反直觉。
根据这个答案：https://superuser.com/a/1747851/705502我制造了一个简单转换器对于某些值：
1 Raw_Read_Error_Rate
7 Seek_Error_Rate
195 ECC_On_the_Fly_Count
原始读取错误率161122843 则得出：
寻道错误率35384631 给出：
硬件 ECC 恢复161122843 给出：
命令超时524287 我们需要根据以下内容手动执行：http://t1.daumcdn.net/brunch/service/user/axm/file/zRYOdwPu3OMoKYmBOby1fEEQEbU.pdf
3.11 Attribute ID 188: Command Timeout Count
Normalized Command Timeout Count = 100 – Command Timeout Count .
This attribute tracks the number of command time outs as defined by an active command being interrupted by a HRESET and COMRESET or SRST or another command
The normalized value is only computed when the number of commands is in the range 103 to 104. The CommandCount and ErroCount are cleared when Number Of Commands reaches 104. The error count used to compute normalized value is not reported in attribute Raw value. It is reported in vendor info area of Attribute sector, bytes 474:475. If Command Timeout Count is > 99, normalize value of 1 is reported. The initial Worst Value is set to 0xFD as a special case.
Raw Usage
Raw [1 – 0] = Total # of command timeouts, with Max hold of FFFFh
Raw [3 – 2] = Total # of commands with > 5 second completion, including those > 7.5 seconds
Raw [5 – 4] = Total # of commands with > 7.5 second completion
根据 Crystal 和 Seatool，我们得到十进制的 30065295359，即十六进制的 00070007FFFF。
因此看起来确实发生了超时。
Ultra ATA CRC 错误计数 1173，根据 Seagate 文档应该解释为：
3.18 Attribute ID 199: Ultra DMA CRC Error Count
Normalized Ultra DMA CRC Error Count = 200 – (#OfCRCErrors * SampleSize /
#SectorsTransferred) where SampleSize = 8000. The attribute is computed if sectors transferred
is >= SampleSize.
Note – Replace CRC errors with R-Errs for SATA drives.
Raw Usage
Raw [3 – 0] = Current CRC/R_Errs Error Count
因此看起来发生了错误。
老实说，我不确定最后两个值有多糟糕或者有多正常。
关于 Ultra ATA CRC 错误，您可能需要检查电缆是否正确就位。从定义上讲，这不是布线错误，但可能是。这种类型的错误不太可能导致异常噪音。
