Got the same problem with the 60GB version. Working fine one minute, my entire music collection on it, films and photo's then it stopped syncing, charges ok though. Went through all the usual steps, nothing. The kind people at creative said format it, I said "But all my data". Just do it and it will be fine. Brilliant now I have a non connecting Zen with no data, "remove the bios, that'll do it" they said, guess what! yep I have a nice heavy smart looking plastic box. "Mmm", say's the nice people at Creative, "Its dead, pick something else and we will give you some discount". Thanks, can't wait to see what they offer me.....
