The problem is "solved". The problem was the to screws that's in front of the flopp drive.
I i removed the inside screw (the one that isn't near the flopp-push-out button, it worked. So, i started the Amiga whithout that screw, when the floppy loaded i screwed it in. After a while i could here i wiered noise from the drive, then i stoped screwing and screwed the screw out again anting the wiered noise stoped. Then i restarted the Amiga. Ang gues what? The floppy drive is working! =D
Sry for the realy, realy bad english in this post, i don't know how to say this things, but i hope you understand some of it, then maybe someone can make another post about it in some type o FAQ or something.
