It’s known as the ‘Brazil nut effect’, technically apparently Granular Convection: https://en.m.wikipedia.org/wiki/Granular_convection It’s apparently not fully explained, but theories suggest things like buoyancy, or that larger particles are blocked from sinking by smaller particles, which on the other hand can slip below the larger ones.
I just walk in and say ‘Good Morning’ in passing, no need for an answer or waiting for them to stop talking. Then I go settle in for the work and if they want to chat they will probably talk to you then. If you were there first I guess you can take the initiative.
There’s some relation in that they both act on fields, but the things that affect those fields are very different (higgs bosons and electrons respectively) and the relationship between all that for an ‘unified theory’ is a topic of much research. IANAP though (not a physicist)
Does it have a hardware RAID card? You may have to flash it to IT mode. The ‘lost’ drive may be just a parity drive?
Did you try copying it with dd/ddrescue?
Personally, I just looked at my firewall’s logs on the WG port and the handshake info. Once you have a handshake I don’t think there’s much that can go wrong on the WG side, maybe there’s a problem with lost packets or network roaming?
