Ciao a tutti.
avevo configurato il PC con RAID 0, nonostante qualche avviso su un errore nel canale B del RAID, ho continuato ad utilizzare il PC in modalità RAID.
Premetto che tutto (o quasi) e su Backup on Line, ma preferirei controllare di persona se c'è ancora qualcosa da salvare.
Sul Pc è (o era) installato Win Seven 64 bit con tre partizioni. Ho provato un recupero con Ubuntu in modalità LiveCD.
Posto alcuni passaggi:
Arriviamo al dunque, ho stoppato l'ARRAY e avviato uno nuovo.
Vedo le partizioni, ma sono vuote
