does the computer recognize it still?
If it does, does the computer lock up when attempting to access it?
If all this is possible there is hope, but for the layperson, that is about all we can do.
I have heard of some people sticking the drive in the freezer for a few hours, that usually only works
when the bearings are going bad.
If the arm that moves the head broke there is not much anyone can do without
opening the drive up, which will void your warranty.
