[FUG-BR] Erros no disco + bonnie++

[mail gter]

Boa tarde amigos,

Estou realizando alguns testes de perfomance de disco com a ferramentar
bonnie++ no FreeBSD 9.1 e o sistema começou imprimir no stderr as seguintes
mensagens:

O disco da1 é um SATA 7200 espetado em uma controladora  HP SAS SC40Ge
(segundo manual).

Estou naquela dúvida: defeito de hardware ou apenas configuração ?
