*No issues with this drive.

This is after I changed out my LSI HBA 9300-8i on 16.00.11.00 firmware to a new LSI HBA 9300-8i running 16.00.16.00 firmware, and I changed out a SAS-8643 to SAS-8643 24 bay backplane to a SAS-8643 to 4x SATA adapter. But the issues persists across the two different setup. I also don't use any 1x SATA to multi SATA splitter, it's all connected to SATA power cables directly from my PSU.

Is this just plain drive issues or is there something more serious going on with my hardware? I run unRAID in a virtualized environment but I passthrough my LSI fully directly to my VM and it's not shared with my hypervisor.

I've tried to dump the logs into LLM for it to do some basic diagnostics but it just turns back blaming a power supply is the issue or cabling but I've swapped all I can so far.

I will be attaching two different diagnostics zip as the latest one doesn't show much info pertaining to the errors. The bigger zip file is what happens when a drive falls out and locks up my whole instance and render it unusable and inaccessible until a reset is performed.

*Adding on, seems like my shares are currently all gone. But the data is still in the drives if I open it manually from the main tab.

That last diagnostics was taken without the array started in normal (not maintenance) mode, so can't tell anything about filesystems since they aren't mounted.

Start the array in normal mode and post new diagnostics
