Eu recentemente encontrei isso também. Como as unidades SSD Asus-Phison relatam incorretamente que o SMART não é suportado, o smartctl normalmente é interrompido sem realmente tentar habilitar o SMART, mas você pode forçá-lo a tentar usar a opção -T permissive
:
# smartctl -s on /dev/sda
smartctl 5.41 2011-06-09 r3365 [i686-linux-3.2.0-23-generic] (local build)

SMART support is: Unavailable - device lacks SMART capability.
A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options.
# smartctl -T permissive -s on /dev/sda

(Pelo menos isso funcionou com as unidades SSD ASUS-PHISON de 4GB e 16GB encontradas no meu Eee PC 900.)
Suponho que o pôster da mensagem da lista de banco de dados smartmontools de setembro de 2008 tinha que usar -T permissive
para obter a saída mostrada lá; muito ruim ele não mencionou esse fato no post ....
