Hard Drive Spins then stops

I rebooted my PC the other day and it came up with saying that
one of my HD was not functional. Un/Fortunetly this was the
drive with all my personal files, and nothing to do with XP Pro.
I’ve tried some of the technics listed on this site to try to get the
drive running long enough for me to pull data, but nothing has
worked. When I power up the drive, the platters spin, but then
when the arms engage them, the platters stop spinning, and
then nothing happens. I am wondering if one of the arms are
damaged, or perhaps the motor the drives them. Any
suggestions or further info needed? Thanks in advance.
