Universal law of tradesmen: They come when you least expect them, and when you expect them they don’t come.
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)
Instantly. Least uncomplicated device on the network. Once I was angry at my laser printer for not showing up, turns out I accidentally left the ethernet cable disconnected afer moving it. Plugged it in, immediately popped up, no wait or restart needed. Prints immediately and effectively, cartridges are easy to replace and relatively cheap, never had stuck paper. Perfect printer.
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.
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?
I think I read something about there being timeouts for slow jobs, which backups definitely are. Really unsure though, it has been a while. Try spawning independent worker programs!
