Data recovery on IDE HDD 80Gb ext3 partition

Question

Data recovery

The disk is unreadable. It is not clear what data is lost and whether it can be recovered. There is a similar device as a donor.

I want to find, on the recommendation of a specific specialist, who is professionally involved in data recovery, knows ext3, in Moscow. Advise from your real experience.

And a parallel question, I already tried to contact one "specialist", he could not tell me whether it was possible to recover the data or not, saying unintelligible things. Is there a checklist for the ability to restore a partition (file structure, sequence of file blocks, what else?) When examining a disk? What to check first? How to assess the possibility or impossibility of recovery at the stage of analysis? Physically subtracting all the data and manually merging blocks without knowing the sequences is very laborious, I would like to have a more systematic solution at the beginning. I want to understand a little myself in order to understand the specialist in the dialogue.

Data: database files.

Answer 1

There are two large branches on xbit dedicated to recovering information from the HDD ( part 1 , part 2 ).
Perhaps the article by Sergei Kazansky and its discussion will be useful ; something can be found on his website .

Answer 2

If there is damage to the surface itself, the storage medium, then no one will ever give you a 100% guarantee for recovery. At one time I had the same problem, the data could not be recovered. There are pros abroad , but here the question arises of the value of the data.
