Is it true that once the disc is opened, it cannot be used?

Question

Hard disks

For example, companies open screws, don't they put them back together?

Answer 1

Open and then use. But most likely not for long.
In the repair area of ​​services, as a rule, a system for removing dust from the air is used.

Answer 2

Yes, you can't.
Data recovery in cases where opening of the HDA is required costs as much as it costs, due to the fact that making such a disk read data at least once is a serious problem that in difficult cases can be solved for more than one month.

Do they then collect them back?

We collect. To be disposed of in the assembled form.
If you are interested in export, you can discuss.
PS
For customers who also want to pick up a failed disk, of course, we always return them (and only to them - the equipment is accepted and issued according to the certificate and passport).
