Due to low space on my MBP I spent all of last night transferring my itunes library onto an external hard disk that was attached to my Airport extreme. The transfer worked, but I found that the lag it caused between playing songs and accessing content on my Apple TV wasn't worth it, so I need to put the library back. I have not touched the original user/music/itunes folder, so all my media is still on the hard drive, but I cannot get itunes to recognise it. I have changed my library location back to default, chosen the organise option, but when I choose "get info" on the files, they all state that they are on my external hard drive, which I have now unplugged. Can anyone help me get my iTunes library back to it's original state? I would be most grateful.
