Hello,

As the $SUBJ says, please post the result of "smartctl -a" on the affected drives for documentation and verification.

Thank you.

Yes, I'm using the APM setting between 6 and 12 months now. If I'm using standard APM settings, the Load_Cycle_Counts increases very fast and there is this clicking noise I can hear.
I'm not quite sure, but I think its rated for over 1.500.000 LCCs.

Can you please turn off APM setting and see how much Load_Cycle_Counts increases in an hour under light usage?

Thanks.

The results:

1 hour surfing, hearing mp3 files: 24 Load Cycles
Then idling for a few minutes: ~5 LCCs/minute

5 cycles per minute. Impressive even w/ 1.5mil rate. Thanks for testing.

Hello,

Attached. It should be noted that this machine has been running with enforced disabled powersaving (by me) pretty much from day 1.

Kind Regards,

Can you please test how much the load cycle count increases on the default setting under light and idle load?

Thanks.
