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.
I've disassembled probably a dozen failed HDAs by now to see how they're
made, but the direction the platters are supposed to turn isn't obvious to
me... should it be 'into' the ends of the arms that carry the heads or
'away' from them? I always thought it should be 'away', so that the
pressure of the circulating air on the arms will lift the heads off the
platter, but on one HDA I took apart the heads tore off of the arms when I
gently turned the platter in the 'away' direction...
