Hello,
One of my HDDs in my NAS started clicking recently. I intend to replace it, but I want to make sure that I correctly pinpointed the faulty one.
I have 5 HDDs in my NAS and I presume it’s the bottom one, as the sound seems to come from one of the 2 drives at the bottom and its activity LED stays lighted up longer than the others when clicking. (Oh yes, clicking is intermittent, the only reliable way I found to make it click regularly was to scroll ~1700 RAWs in Darktable.)
Is there any indicator that can confirm this is the faulty one? Long SMART tests obviously report nothing and all drives have the same temperature. Maybe a latency test? I’m not sure how to conduct that on TrueNAS (my pool is a 4-wide RAIDZ1 with one Hot Spare)
Thank you very much!
A mechanic’s stethoscope will make it pretty easy to figure out where the noise is coming from.
