Hi all, I am using an external hard drive that is connected via USB 2.0 to my Airport Extreme to back up using Time Machine. In order to get Time Machine to recognize the hard drive in question, however, I had to mount it as a drive on the network. Can I put a password on the hard drive that is separate from my network's password? What I want is a situation in which people can get onto my network using a password but CANNOT access the Time Machine backup hard drive. Thanks!
