During last nights tech forum Mark Said he just hooked up a 2TB HD to his system and it works great......an email or two later someone asked about adding an EHD to his 211k....one of the experts in the peanut gallery said the drive had a Min of 50GB and a Max of 1TB Huh???..... So which is the Max is it 1Tb or 2TB?....I have a 722....If a 2Tb works what brand works the best...
