A couple of months ago I got myself a LaCie Ethernet Disk for home usage and sharing my photos, videos and of course music files. The goal was to make the Ethernet Disk available to all laptops and stream music, with Airport Express, to my home sound system.
Well, all works quite well and I have to say that Airport Express is such a useful gadget. Be it at home or on the road, it is worth every penny.
But the problem I had lately was that music files I put on the Ethernet Disk did not show up anymore within iTunes. I thought it was because I still had an older version of the firmware and thus updates to 18.104.22.168. Still, my music files did not show up in iTunes.
Further searching I found this blog post which described the same problem. I downloaded the fix (iTunes Server patch) and applied it to my Ethernet Disk. After updating the Disk you will have to rebuild the media database, but I am happy to report that the fix solved the problem.
