In a previous blog posting ("Migrate your iTunes library off your local hard drive") I wrote about how to free up a bunch of hard drive space by moving your iTunes library to an external USB hard drive that you then attach to the new 802.11n AirPort Extreme Base Station (AEBS). Stop the presses!
This setup worked for me for about three days, then suddenly iTunes couldn't find any of my music. I got a horrible sinking feeling after clicking on track after track only to be greeted by the ugly error that my music couldn't be found and "would I like to find it?" Ugh.
Preferences > Advanced > iTunes Music Folder Location... points to the right place
Advanced > Consolidate Library - doesn't help
The craziest thing is that some tracks play just fine (a couple dozen at most). Getting info on them (Command-I) even shows that they're in the right location. So how, may fair reader, can 1% of my library be found whilst the other 99% is now missing?
Do not move your iTunes library to an AirDisk (my term for a USB disk connected to the new AEBS) until this issue is resolved.
I think that I'll just upgrade to one of those spacious new 300GB mobile hard drives instead.
