Hello,
Although a smartctl check in one of my server's drive indicates the health status as being OK, I notice that the smartctl output also indicated some errors on the drive. From my understanding the "Errors Corrected" is the number of errors the system was able to auto correct and the "Total uncorrected errors" are the errors the system was not able to fix.
Should I be concern about total uncorrected errors smartctl is detecting?
Also, according to the documentation (
http://smartmontools.sourceforge.net...ools_scsi.html), the "Non-medium error counter" represents the number of recoverable events other than write, read or verify errors. What would this events be?
