iTunes move to external hard drive
I have run out of space on my 2007 Mac and have purchased an external hard drive in order to free up space on my Mac hard drive. I have moved my itunes library to the external hard drive. Before I delete the itunes library in my mac hard drive, I would like to be sure that the entire library has been moved. The problem that I can not figure out is when checking on the storage capacity of my hard drives, the mac hard drive shows 117.91 gb of audio storage and the external hard drive only shows 6.18 gb of audio storage. The descrepancy scares me. When I open the external hard drive's library, it all seems to be there. I have over 70 classical albums, plus another 70 pop/jazz/etc albums. The first time I moved itunes to the ext. hd, I just dragged the icon. The second time, I consolidated my entire itunes library into a folder and dragged that over. It didn't show any change in the external audio usage. Can some one give me advice?
