I have a similar problem. I have four 8 TB WD drives, Ryzen 5 1600 CPU with 32 GB of RAM. I originally started off using TrueNAS Scale but ran into issues with the NAS hanging; only a hard shutdown via the power button would bring it back online. I thought it was the motherboard (cheap Aliexpress SOYO model) so I recently swapped it for an ASRock B450M/ac R2.0 one; decided to try unRAID 6.12.6; once everything was setup, same problem as before; the NAS keeps hanging. At this point, I'm not sure what to try next. What kind of logs can I provide for troubleshooting? Thanks.
