OK, acho que descobri:
- Examine o log
dmesg
para verificar a memória endereçável suportada pelo dispositivo USB. - O Linux parece impedir o uso de um disco rígido se exceder a memória endereçável de um dispositivo USB. (Com vários erros).
- O Windows permite o uso de um disco rígido, mesmo se ele exceder a memória endereçável de um dispositivo USB. (Até que o limite de endereço seja atingido.) (Então o problema era ... Windows?)
A mesma unidade, diferentes gabinetes resulta em duas capacidades diferentes relatadas:
-
7814037168 512-byte logical blocks: (4.00 TB/3.63 TiB)
-
3519069872 512-byte logical blocks:(1.80 TB/1.63 TiB)
