I received over the past few days notifications that my error count increased from 0 to 1 on three of my drives. Question I have is how concerned should I be? Results of the SMART test are below. All of the errors occurred "at disk power-on"
CRITICAL: June 24, 2017, 2:07 a.m. - Device: /dev/ada1, ATA error count increased from 0 to 1
CRITICAL: June 26, 2017, 12:37 a.m. - Device: /dev/ada0, ATA error count increased from 0 to 1
CRITICAL: June 29, 2017, 7:40 a.m. - Device: /dev/ada2, ATA error count increased from 0 to 1
CRITICAL: June 24, 2017, 2:07 a.m. - Device: /dev/ada1, ATA error count increased from 0 to 1
