In terms of data recovery using software, most of these offerings have a friendly-user interface and they basically they can execute similar kinds of tasks, such as reshaping corrupt partitions, recover accidentally deleted files or folders and unintentional formatting.
But when you use the service of a specialist, the data will more or less be recovered.
However, their expertise may have set you wondering at times - how did they do it? Here I will outline some of the procedures they use.
The first thing they will do in their laboratory is to analyze the media.
These media analysis procedures are usually conducted in clean rooms.
Tightly controlled ones are very expensive, so expect only those branded and well-known data recovery experts to have such a facility.
From these analyses, the technician would know the extent of the damage or corruption that had occurred.
This group of individuals knows what they are doing so you can be assured that you will at least get back most, if not all, the data that you have lost.
The standard procedures are once the analysis is completed, they will inform you how much data can be recovered, when the recovery can be completed and the estimated cost cost.

If your data is highly confidential, such as secret photos, important trade secrets or data on a project you are working on, then you need to have a non-disclosure agreement signed.
In trying to recover your data, it is a common procedure to make a copy of your media so that the integrity of your media is not compromised in the event that something goes haywire.
Which means all recovery effort will actually be on the copy, not the original one.
In established joints, the standards used will ISO 9001 compliant.
Depending on the content of the original quotation, the data recovery firm may send you another confirmation document and attached with it are the outline of the data they had come across.
If you are happy with what you see, then give them the green light to recover the data back based on your instructions.
