platters looks weird

[sosrecup]

Hi,

Is there a chance/solution/technique to recover data from a such disk (HDS725025GLA380) :

What you see is massive media damage
All data is in the filter now
Cannot be recovered

...drive is toast.

Thank you for your reply.

Could anyone tell me what could cause this damage please?

HSA sliders filed down the surfaces

I would guess the top slider came off and the arm was just scratching the surface for some time.

What if you ran the spindle motor backwards, would it re-deposit the data? And could quantum entropy software decode it?

This reminds me of a drive that's been in the freezer and then powered on.

Sorry for offtop but I have question about the "dust" on the filter. What is it this "dust", it is the rest of the magnetic layer that platters are covered?

Yes, it is platters' top layers shredded to dust.
That dust is in the filter, as well as it's the origin of the "ornament" on the surfaces

The surface texturing you see is part of the raw/crude first stages of polishing the platters.
