Thanks for the responses and the advice.
Apologies, i do not have 4500 tracks, that was a typo i actually have 1500.
As for the suggestion of switching usb mode I understand what you are saying but the results for each are the same, I had tried the two different modes prior to posting here because i am the type of person who experiments before asking for assistance.
I feel this is a FW glitch although I seem to be the only one with it which is strange, like I mentioned previously there was no problem prior to the FW update and my usb mode was always auto detect.
If I do a format then I will lose the tracks on my Fuze right? These tracks were self selected by me and I do not sync my fuze with WMP or similair so it would be time consuming to go through the process again.
Have to say that the FW update has been a massive disappointment, you wait all that time for them to provide very little useful updates, with the majority of it being cosmetic, some additional features which are useful for about 1% of owners, while completely over looking the most basic requirements like a good search facility to name just one.
Any way thats off topic and my little rant over with.
If anyone has any other suggestions then it would be appreciated.
Despite this I think the player is great.
