Is it true that it is impossible to open the hermetic block?

Question

Hard disks

If you open a hard drive, where the pancake is spinning, and then tighten the lid and copy the data from the screw, what will happen?

Answer 1

Most likely, you will simply screw up the disc due to the smallest particles of dust that will fly in there and stick to the head / pancakes.

Answer 2

Yes, it is easily opened in a dust-free block.
Well, you won’t be able to copy the data in this way.

Answer 3

Nothing will happen right away, but, due to dust, the service life will decrease.

Answer 4

Depends on the purity of the atmosphere in which the autopsy takes place.
In a laminar flow hood with good HEPA filters or a clean room, you can open it, at home - definitely not worth it.
In addition, if the disk has been in a running computer for some noticeable time, dust accumulates around its perimeter under the cover. If you haven't opened enough discs before, you're very likely to shake off that dust on the platters. The result will not please you.
