I first thought that the disk is defect. So I sent it to IBM witch replaced the disk. I now have another one.
I find it strange, that the disk has problem to read data during driving. (the ticking) I don't have a special car, so I think it should work. With the original disk I had never problem during driving.
If this is a common problem, I think other people must have the same.

My mp3 are ready to reinstall. :-) The disk is nearly empty at the moment.
