I had disabled this when I wrote the OP, but had not set it in /etc/hdparm.conf. Today I did that and the Load_Cycle_Count seems steadied at 3781, though it is still under observation. When I wrote the OP I got an impression that -B255 isn't helping, because I wasn't aware of Load_Cycle_Count and I measured the disk activity by the following command: iotop -obqqqq --delay .1 This still continues to show kworker doing some activity: 103 be/4 root 0.00 B/s 0.00 B/s 0.00 % 0.87 % [kworker/1:2] 103 be/4 root 0.00 B/s 0.00 B/s 0.00 % 0.73 % [kworker/1:2] 103 be/4 root 0.00 B/s 0.00 B/s 0.00 % 0.70 % [kworker/1:2] 103 be/4 root 0.00 B/s 0.00 B/s 0.00 % 0.72 % [kworker/1:2] 103 be/4 root 0.00 B/s 0.00 B/s 0.00 % 0.72 % [kworker/1:2] 103 be/4 root 0.00 B/s 0.00 B/s 0.00 % 0.69 % [kworker/1:2] 103 be/4 root 0.00 B/s 0.00 B/s 0.00 % 0.84 % [kworker/1:2] 103 be/4 root 0.00 B/s 0.00 B/s 0.00 % 0.86 % [kworker/1:2] 103 be/4 root 0.00 B/s 0.00 B/s 0.00 % 0.86 % [kworker/1:2] 103 be/4 root 0.00 B/s 0.00 B/s 0.00 % 0.89 % [kworker/1:2] 103 be/4 root 0.00 B/s 0.00 B/s 0.00 % 0.92 % [kworker/1:2] 103 be/4 root 0.00 B/s 0.00 B/s 0.00 % 0.84 % [kworker/1:2] What to attribute this disk activity to? I have tried checking using lsof whether any files are changing that fast (such as syslog) but that is not the case.
