两周前我通过电子邮件收到以下错误：
The following warning/error was logged by the smartd daemon:
Device: /dev/sda [SAT], ATA error count increased from 0 to 15
Device info:
ST1000LM035-1RK172, S/N:WCB0Z83A, WWN:5-000c50-09c2b85e7, FW:SBM3, 1.00 TB
我检查了驱动器的智能数据。
显示Current_Pending_Sector为：0
自我评估似乎也很好：
SMART overall-health self-assessment test result: PASSED
除此以外，我没有在系统日志中发现过去一周左右的任何最新警报：
Jun 19 22:44:37 raspberrypi smartd[416]: Device: /dev/sda [SAT], SMART Prefailure Attribute: 1 Raw_Read_Error_Rate changed from 80 to 81
以下是 smartctl 的输出：
