I finally got that screw out. T-6 torx. Had to first run a thin flat screwdriver around the edge; was it stuck? Well, now to look at the whole thing, the arm seems like it sticks as it comes out of the parking area (am not very fluent in all the tech stuff denominations of the parts themselves), so it keeps clicking as it tries. So I can move it manually (the disk spins just fine when the arm is parked), but it seems like it snags at the bottom right before getting to the plater. Probably no hope. Then the arm is fine, right above the platter. System sees the drive sometime. But, wrong size now. Used to show 243201 cylinders, but now over 14,000+ Then it just goes quiet and quits. Yep, no more Seagate for me.
