5310 can't transfer music

Question

Whenever I try to transfer music using PC suite it converts it and puts it in my collection folder but then as it tries to transfer it to the phone it comes up with "unknown error".Sometimes it will get half way through copying before the message appears sometimes at the start there seems to be no particular point that it fails. If i try to drag and drop them not using PC suite it comes up "phone not responding" or "unable to complete operation". it all started when I was Deleteing old contacts through PC Suite and it froze. At first I couldn't amend contacts either as you would click on a contact and it would pop up for a fraction of a second then disappear but on updating pc suite this problem is solved but still can't transfer music.using latest phone software update v 05.81 according to updater. can some one help

Hello, and thanks for that. Unfortunately I've already tried the restore road and it still does it?
The ipod shows up OK as a drive and in itunes. Its only when I try to transfer video's music etc then it starts the process after a few seconds the ipod HD starts clicking disappears from itunes and the ipod goes to the green apple black back ground and resets itself.
If anyone has any idea's please let me know before I jump up and down on it
