Su /dev/sda non c'e' il sistema operativo.
Debian Squeeze 6.0.2 e' installato su /dev/sdb
Io vorrei usare l'hd su cui e' installato il sistema operativo, come
disco principale. Credo che bisognerebbe scambiare /dev/sda e /dev/sdb.
Cosi' da avere sdb sul disco secondario, che se c'e' o non c'e' non
cambia nulla per l'avvio del sistema.
Il disco secondario, lo potrei usa come copia di backup (un clone pari
pari) da tenere in caso di guasto del disco principale. Da collegare
fisicamente al posto suo su SATA2.
Oppure per installare delle versioni nuove del sistema.
Ciao
Claudio
