Hi all,

I just connected a 2TB My Book (Essential Edition) to the Apple TV to use as the Primary Drive and all went well except that it is showing in iTunes as only 1.86TB. Is there a reason for this? 160gigs seems like a fairly big difference.

By the way it was formatted Mac OS Extended (Journaled).


Monkey A**

Yes, that is normal. The AppleTV uses the ‘old’ way of counting, so a 2TB drive will appear as less than 2TB.
