Western Digital also started to manufacture Very Slim 2.5'' HDD WD10SPCX-08HWST0.as per attached Picture..but can't understand what is advantage of this type?can't remove Head without Removing Platter.no space to swivel head to out.this destroying data recovery confidence.anybody have experience with this model pls share it.attaching picture.

I doubt that at the factory they placed the head stack along with the platter at the same time as one assembly.
Can you take a pic of the drive when the head stack is all the way out to the end of the ramp and of course with the top magnet and stopper removed?
