Hello ppl, Need some info on this hdd: http://www.amazon.co.uk/Western-Digital-MyBook-Firewire-External/dp/B0016M27YS/ref=sr_1_10?ie=UTF8&s=electronics&qid=1209587990&sr=8-10 AFAIK, there's two harddisks inside this enclosure. But, can you use the harddisks as two separate partition? ie, to make two backups, so when one fails you have another to fall back on? Is this a good idea to use it as such? Thanks!
