You have just been conned. I replaced my 40G iPod with the new Classic 160G last November. I have been trying to download 10,000 songs but then everything (iPod and iTunes) freezes,sometimes after 5 songs, sometimes after 150 songs. The most i have managed to get on to the ipod was 3,500 songs but guess what!!! The iPod reset itself and everything was lost on it. Now for the really Big Scandal log on to this http://discussions.apple.com/thread.jspa?messageID=5324590 and see how many others are experiencing the same problem. Apple have yet to acknowledge the problem. and their Help Desk is useless. THIS IS A SERIOUS MATTER. I am getting in contact with the Director of Consumers Affairs to get asking him to act urgently on this before more people are conned. I was about to buy an Applemacpro laptop but not anymore. Latest update on my problem. I got in touch with Apple Customer Service Team by writing to them. They phoned me and arranged for the collection of iPod to bring it to their laboratory. They found that the running system was not working and they replaced it with a brand new iPod which works fantastically well. So the moral of the story is to contact Apple directly and don't suffer malfunctions. Let them sort it out and I am sure they will.

my ipod freezes too. i cant even listen to my music anymore.. it says thtere is nothing on it and tht m harddrive is full.. but it has nothing on it.. it was all deleted or somthin.. and i plug it in and my ipod wont sync and itunes freezes on me..

I've found the solution!!! I had the exact same problem. My itunes would keep freezing and I would get the blue screen of death (which is the first time I've seen it on Vista...kinda cool) Anways, what you gotta do, is connect ur iPod to ur computer. iTunes will run and connect ur iPod, but it won't sync to iTunes. This is typically when iTunes freezes, so you have to close iTunes (Alt + Ctrl + Del) or by clicking the X button maniacly to close it. Go to My Computer, and you should see a separate drive for your iPod. Right click it and click on "Format." (KEEP IN MIND: this WILL delete everything on ur iPod, so make sure all ur music/movies/pictures are still all on ur computer) Then just click format and it'll ask you, are you sure? Say yes. This takes awhile...around 30 minutes to an hour. I lost track of time while it was reformatting. Then when you open up iTunes again, your iPod will finally sync, but Restore it, so that you basically just reset ur ENTIRE ipod so it's as if you took it out of its box yesterday (Minus the scratchy exterior). Then it's as if it's brand new. Put music on it and sync, and VOILA!

MiAndChoi, you're a genius! After hours of searching the internet and trying other suggestions, yours was the only one that actually help resolve my freezing iTunes. Thanks a million.

do you format as fat32 or nfts, I appreciate I will lose all my songs but have them backed up but if you format do you not need to reinstall certain software or files on the ipod and if so where would you get these from. Seems just to easy to reformat and then say hey presto.

When I try this it states that I do not have "sufficient rights" to do this on my computer. I am the administrator on my computer but is there something I need to configure in order for this to work?

My ipod is having that problem now. On my old computers it was working excellent but now itunes keeps freezing.. Tried MiAndChoi's suggestion but when I go to format it, it says it can't format. :|
