SMART Error Log Version: 1
ATA Error Count: 749 (device log contains only the most recent five errors)
CR = Command Register [HEX]
FR = Features Register [HEX]
SC = Sector Count Register [HEX]
SN = Sector Number Register [HEX]
CL = Cylinder Low Register [HEX]
CH = Cylinder High Register [HEX]
DH = Device/Head Register [HEX]
DC = Device Command Register [HEX]
ER = Error register [HEX]
ST = Status register [HEX]
Powered_Up_Time is measured from power on,and printed as
DDd+hh:mm:SS.sss where DD=days,hh=hours,mm=minutes,SS=sec,and sss=millisec. It "wraps" after 49.710 days.
Error 749 occurred at disk power-on lifetime: 6972 hours (290 days + 12 hours)
When the command that caused the error occurred,the device was active or idle.
After command completion occurred,registers were:

Selective self-test flags (0x0):
After scanning selected spans,do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up,resume after 0 minute delay.
解决方法
如果可以,请进行更换.
另一方面,这些是“唯一的”读取错误并没有那么糟糕.如果你写信给那个部门,那么你只能确定它是否有缺陷.
如果有问题,我会运行供应商实用程序来检查(它们也运行智能测试).他们通常会提供可启动的CD.
你可以而且应该运行一个自测试,你可以通过发布来从linux做
smartctl -t long /dev/your-device
等几个小时(它会显示估计).然后再次检查
smartctl -a /dev/your-device
如果它说完成没有错误你没事.如果没有去供应商实用程序检查驱动器.
