I bought a shuffle for my girlfriend recently and installed it on her computer. There were no problems and it worked fine. However, when I took it to my house (because I have more cds, and a mac) to put some more songs on there the shuffle would delete the songs I have just imported into my library (from the cd) then deleted from the hard drive (because I don't want all my cds to take up hard drive space). This is very strange, any way to fix the problem allowing me to delete songs from my Library that I have copied to the Shuffle then deleted? thanks!
