Disc in raw. How to return data?

Question

Hard disks

After a power failure, the portable drive is in raw.
Tried chkdsk d in normal and safe modes - didn't help.
Tried r-studio - scans, finds data. But it does not restore, hangs, hangs for days. Sometimes, when loading a file with scanned data (a file with the .scn extension) closes. Tried different versions - same result.
How else can you drive a hard drive to recover data?

Answer 1

try EasyRecovery, it often helped me, look here
remontka.pro/recover
rlab.ru/tools/rsaver.html

Answer 2

yes, in principle, this is due to the fact that the disk got damaged
here in two moves
if the data is very important, go to an office that specializes in data recovery
if the data is not important, select only those that need to be restored, and not all data, since the studio falls on broken sections more likely

Answer 3

First, adequate people use niks for data recovery. Thanks to the curved architecture of windows. Secondly, what data and what kind of file system was it?
Finally, if it's text, then the rudimentary strings utility on /dev/sdX should help. Although you will have to work with your hands, scattering data on the shelves, and there will be a lot of them, a lot. And so, usually enough foremost or scalpel .
However, before you start, I advise you to make a disk image dd if=/dev/sdX of=/home/username/sdX.image, although this will require a lot of memory. You can compress inline with gzip.
UPD.
I forgot to write that if the disk is deformed, then hardly anything will help, and its use will only harm. If you can kill a couple of million raccoons for data, I advise you to turn to professionals.

Answer 4

Test Disk.
