AAAaaaaaaaaa!
DON'T HIT IT!
At least not yet. If it boots windows the control electronics are OK; thats
a good sign. That you can boot Windows says that the basic head movement
is sound too, also a good sign.
So then, I'd say that an op-amp on the disk isn't working, or something like
that such that parts of the disk aren't readable. The clicking sounds you are
hearing are signs of the control electronics being confused during a seek
and the heads retract in an attempt to recalibrate.
My trick is to take the disk out and cool it in the freezer. Not to make it
it super cold, but definitely cold to the touch. Then stuff it back in the
system and try to reboot it.
If that doesn't work, make it colder. Usually the first pass will bring
the disk to life briefly. There have been times when I've had to get
a disk colder to read it, but usually it works. Usually.
Hitting a disk is akin to gently letting a wrecking ball hit your car.
Yes, it can work--it can dislodge small (microscopic) parts of crud
clinging to the heads, or unstick head arm, but this isn't something
I willingly do. You can kill the disk completely, if you wind up moving
a head thats loose at the end of the arm. Making it move a few microns
can result in a gouge and thats the end of the disk.
The other trick is to put the disk in some other machine such that you
aren't booting from it, but mounting it and perhaps data can be read
off the disk during the first nn seconds that the disk is on. I have one
of those here at home--it works for about 40 seconds then fails.
If you want help email me. People at work think that I have a plentiful
supply of rabbits for disk disasters....
