Not
specifically for the RD53, but I've had winchesters that don't spin...
Firstly, I assume you openeed the HDA to free the heads, Can you try to
rotate the disks in the correct direction (obivous if you look at the
heads).
Just to make sure it's not mechancially
jammed.
Yes, I freed the heads, even though RD53s turn the disk if the pads have
turned to goo and stuck the arm. The disk turns freely when I turn it by
hand.
Common causes of problesm with the spindle motor electronics are the
power transsitors that drive the motor windings, whcih are easy to test
and
replace, and the hall-effect sensors inside the
motor, which are almost
impossible to get to

I have a copy of the fiche for the RD53, it is a bit hard to read but I will
see if I can find where these components are.
