Problems with large music directories  

Is there a known issue with the 105 not being able to read large folders of music? I can FLAC and AIFF from small folders 100GB, but larger directories >500GB it doesnt do anything. I click on it, it says loading for one second and then it goes back to the root directory. I let it sit there for 30 minutes to do the indexing by itselft, but nothing. I tried this through the Network (where i can read smaller directories) and nothing. I then hooked up a 2TB full HD through the DAC USB and nothing, same thing; just stays at the root directory and does no indexing.

Anyone having these problems? The 2TB is connected directly and is formatted to attach to the Mac Time Capsule (which is where I was able to access the smaller folders via Network)

Thanks
