synching issues

[pkay1]

I had to connect my new ipad to my pc to install some mp3 files but even though the music only took up one and a half gig I have lost five gig since synching according to my ipad usage statistics.
Absolutely nothing else was transferred to ipad and it is driving me potty.
Please what have I done wrong ?

Are all the MP3's you tried to load associated to your iTunes account? If any of the music you have on your iTunes is associated with another ITunes account then that might be the problem. You would need to login into the other iTunes accounts and authorizes the PC or Mac to use the purchased music before it syncs.
