Here's a photo of a tiny read/write head from a laptop hard drive. To give you a better sense of scale, I've positioned it to look like a mustache on a dime, making Roosevelt's visage appear like his WWII nemesis.

A 2 TB laptop drive has 8 of these tiny heads in a stack. Sometimes we have to spread them apart and clean them . . . all under a microscope. The heads are very delicately attached to arms. One small mishap and the head stack is toast.

nice scale comparison .... puts a perspective on the "should i take the lid off and.." type of questions we see.

And sometimes we have to recover the data even when those heads look funny, not like a stack at all.

Unfortunately, at this moment I can't tell for sure what was the story behind that job. During their infrequent spare time our guys also like to do different interesting things and taking such pictures is among them.
So I just pulled this photo, but the file name contained nothing besides the model. Also modification date is mid-2011, so no way to remember what happened back then.

But generally yes, that's either a physical influence or a power loss at an appropriate moment (quite possible thing for a drive with outward parking).
