Eu tenho um PC embutido com um sistema operacional Debian e OpenMediaVault para compartilhar recursos através da LAN. Eu tenho um gabinete externo USB / SATA com 1 TB HD. O gabinete USB e o HD funcionam bem conectados a um PC de mesa (Windows, Linux).
Quando conectado ao meu servidor incorporado, acontece que o disco "desconecta" depois de ler ou gravar arquivos bastante grandes (ou seja, algumas centenas de MB). Não tenho certeza se é um problema de hardware ou relacionado à configuração.
dmesg mostra muitos erros:
