I am having exactly the same issue - did you ever get it resolved? One difference with mine: After various troubleshooting (removing ram, starting with no battery, etc.) I left it for 2 days, then miraculously it booted. However, then I put it to sleep and now have the same issue again. Any tips on what your issue ended up being? Thanks! <M>

I've done this operation twice, and it was missing from my computer both times....

The bent metal clip on the right hand side can make the drive seem stuck, even once all 4 screws are removed. You can tilt the drive forward and gently wiggle it up and down to see the clip coming out, and pull by the clip to remove the drive.
