Why the desire to scold people for attempting to fix a broken HDD? Even the referenced article seems to want to underscore the idea that it's impossible.
I personally have recovered data from failed drives (including modern ones) using the freezer, the hammer, the heat, the platter swap, the PCB swap and just removing the cover and freeing a stuck component. I've failed but more often I've succeeded. Clearly the people shouting about it being impossible are not using real-world experience to base their opinions on.
For most people the $2-10K recover fee is simply out of the question and in their case at least attempting, though increasingly extreme measures, to get the drive to spin up one last time is the most rational choice since the only alternative is to toss it in the trash.
