What is the best way to copy files from a dying drive?

Question

Hard disks

The other day there was a task to save the warehouse inventory database from a half-dead disk.
The problem was the extremely low speed of its work (up to the fact that folders opened for 1-2 minutes, with a chance of completely freezing) and copying (up to 400kb / s on a 3.0 flash drive.)
Are there any programs that can temporarily revive disk?

With this information, I'm afraid you're on the brink of disaster.

Judging by the description, the disk is clearly dying. How long it will last is impossible to predict. The best option is to turn it off as quickly as possible, and not touch it at all (not even turn it on).

Are there any programs that can temporarily revive the disk?

There are programs that, behind beautiful (but false) words, hide the abuse of the internal systems of the drive, attributing the results of this as their own achievements.
In your case, various HDD Regenerators and similar rubbish are categorically contraindicated, tk. you need to save the data.
John Smith is right. Given that the data is not yours, but belongs to the company, and especially due to the fact that you need a database, and not, for example, photographs, you definitely need to contact specialists.
Databases, videos, and the like are the most problematic content in terms of maintaining integrity (serviceability / performance). The disc is either starting (or has already started) problems with the surface, or problems with the heads. It could be both.
Before you start playing Russian roulette on your own, choose a data recovery company and go there for a free diagnostic. So you at least have an understanding of what scale of the problem you are dealing with.
And it is better to hand over the disk to them for work. While it is still somehow alive, there is a chance to subtract the base you need without replacing the head unit. Those. how not to miss the opportunity to solve the problem in general, and to do it at a very affordable price (even for a private person, not to mention a company with a warehouse where accounting is needed).
You can try to make a disk image, for example in gddrescue (GNU ddrescue), but this is an unnecessary risk. You will read who knows what, while not being able to control the state of the heads and the readable surface, and at least make timely correct passes.
After that, everything can go downhill - first, the difficult work of data recovery (getting the right files), then - it is likely that the work to "repair" them, because. the probability that a 100% complete copy cannot be made will greatly increase.

No, if the data is important, then only a service center, I recommend rlab
