As I said on another thread re backing up my iPad, I have had to reinstall Windows Vista so have downloaded and reinstalled iTunes. I had copied away my music to an external hard drive so have now copied it back but it's not showing up in iTunes on the laptop, I can only see a couple of downloaded albums (all the missing ones are ripped CDs). The music is in the folder C:\Users\myusername\Music\iTunes\iTunesMedia\Music. I checked the backup and it appears that it was previously in C:\Users\myusername\Music so I moved some of the music to here but it still doesn't show up in iTunes.
I hope I've explained clearly enough and that someone can help please.
