So just in case anyone has the same issues, I did some diagnosis over the weekend. The drives I'm currently using are shucked white label WD drives from Easy Store units. These units require one of two things to power on, either a 3rd pin (3.3v power) modification where this pin is covered in tape to prevent it making contact with the connector, or the use of a molex to sata connector. I opted for the prior, as I did not have a molex to sata adapter on hand. Upon taking all the drives out of the system, one of the three 12tb drives had the tape slide partially off of that connector, causing intermittent power and thus the drive to disconnect abruptly. Not quite sure how this would happen out of the blue, but none the less if you opt for this modification, double check the tape if you have any issues. Thanks for the help trurl!

I'll check connections and replace all the sata cables to be safe. Any other known causes for this? only running 4 drives and all plugged direct into the MB

Here's a newtower-diagnostics-20210923-1444.zip log, the error occurred on my system at 0212, still trying to figure out this issue.

Will do, thank you

Hi all, I'm experiencing quite a bit of frustration with one of my drives in my array. Every 24-48 hours or so, when i go to my main dashboard, one of my drives shows a * for temperature and its data is inaccessible. When I boot the array into maintenance mode, I can do a filesystem check and repair, which results in a mountable drive with my data still present. After running the extended SMART test, everything came back as good and all of my pre-fail and old age indicators are clean. Not sure if its UnRaid or one of my docker applications causing this issue, but it's definitely worrying. Thanks in advance
