many thanks for the reply.

yes, i have check the drive with computer supply, i think heads are moving because i can feel some jerk in both direction while holding it in hand, but spindle is not moving.
with power on condition, i check voltage using multimeter on motor terminal, no voltage on all 4 contacts. it must show some volts on that contacts when drive is power on .
height of falling is not much only cabinet height, because my cabinet was on the floor. but when it droped both sata & power cables were out from its connecters.

please suggest some diagnostics i can try myself

thanks!
