Hello,
I'm seeing alerts in the syslog about SMART errors on my disks.
Code
Feb 6 15:22:21 openmediavault smartd[3379]: Device: /dev/disk/by-id/ata-Hitachi_HDS722020ALA330_JK1175YAHYVU5X [SAT], SMART Prefailure Attribute: 1 Raw_Read_Error_Rate changed from 100 to 99
From what I understand, the Raw_Read_Error_Rate met down the VALUE score from 100 to 96 and as long as the THRESH flag is not reached it works ? Or am I completely wrong and the hard drive is slowly dying ?
Code
