Hi. I noticed some noises coming from my Unraid server the other day using the mover from my cache drive. Today I noticed a louder noise when I had my cache drive in use but not using the mover.

I installed Scrutiny to check the SMART results on my hdds. I have this warning for my parity drive.

I swapped cables then switched SATA ports and the warning persists. I wonder if I should just keep an eye on this drive for now.

My SMART results:

According to that the attribute is 0, post a normal SMART report from Unraid.

This is my parity drive by the way. I ended up getting this from the diagnostics. I noticed on Scrutiny that the hdd is showing that the drive is spinning down at midnight for the last 3 nights.

That's fine, false warning from that app.
