No, using the T2's audio recording capabilities only works with an internal harddrive. And understand also that not all external USB devices are guaranteed to work with the T2. I have a very sweet Venus DS3 External Enclosure (USB) in which I had hoped to mount a used external harddrive for T2 internal drive backups. Unfortunately, it doesn't work with the T2. And, as for the T2's USB ver -- it is 1.1.
