Sometimes if the drive is already siezed, you can try putting it in a static bag and leave it in the freezer overnight. Then sometime the next day pull it out and plug it in real quick before it starts to thaw out. By doing this you've shrunken all the little parts inside and it might be just enough to unstick it.
Let it spin till its warmed up and dry again grab you're data off it. Or if you're lucky like me, continue like nothing happend
