How can i fix my creative zen microphoto mp3 player?

does anybody know what the most likely cause of 'hardware failure' would be if my zen was dropped into water. i took everything apart to get it to dry out. But it had been a few hours since it happened before i got home.

Will it be the drive?

The only thing that gets anything to happen is plugging it in- then 'hardware failure' comes up, but the computer doesn't recognise it

Anybody any ideas as to how to fix it?
