I have 3 samsung F4 2TB HDDs.
Two of them are for RAID1, and one of them is for backup.
They worked fine until I applied linux software RAID1(which I'll call MDRAID1 from now on).
With mdraid1 running, they make clicking sounds every 15~20 seconds.
Whenever I hear a click, "smartctl -a /dev/sda and /dev/sdb" shows that Program_Fail_Cnt_Total increases by 4.
Let me show you the output of mdadm and smartctl for both drives.
As you can see in the below, Program Fail Count is too high for power on hours.
Plus, Calibration_Retry_Count is already 2 for /dev/sda
Why does Samsung F4 have this problem? and what's the solution?
There was a new firmware for F4 last month that fixed smartctl trouble, but this is a new issue.
