A while back I decided to get a ShareCentre DNS 320 from DLink as a NAS (Network Attached Storage).
Since the update to iTunes 10.5 which saw some changes made to how the application communicates, iTunes no longer displayed my Shared Drive, insisting that it was “Loading” the data.
Anywho, there has been a recent release of a BETA Firmware Update from DLINK, so use it at your own risk. It was updated on the 30th of March, 2012.
Link to it is here: ftp://ftp.dlink.com/Multimedia/dns320/Beta/Firmware/
Fireware Update is found in the System Management section of the Web Interface for the DNS-320.
