hi all, i've got a MacMini here running OSX Lion. i've got an external USB HDD running Time Machine and i've been keeping daily backups for the past 6 months. i just wanted to know how i could restore the HDD if it were to die. if i bought a new HDD tomorrow for example, how could i get my system running back to where it was running today with all of the current settings and files etc? is it easy to do? thanks, i'd really appreciate any help!
