The following barbarism was performed on the Hitachi IC35L020AVVA07-0 (20 Gb) hard:
- connected as a slave, but the jumpers were first set incorrectly, to the 2 Gb clip position
- in Windows, through the disk manager, over the visible partition (which was visible in size 2 Gb) performed an action mark as active

As a result, a 2 Gb partition is now visible, which is not readable, and the remaining 17.7 Gb space is visible as unallocated.

Is it possible to recover data from it, and how?

Try the open source www.cgsecurity.org/wiki/TestDisk , it once saved me in a veil loss situation.

GParted helped me once . I also killed the partition table then when installing Linux. :)

In any case, for starters, it’s worth doing ddrescue (or something similar) so that after unsuccessful advice you won’t be left completely without data (ddrescue takes images from devices, regardless of the presence of partitions or anything else on them, who doesn’t know)

Set the jumper back to 2 GB. If the disk is readable, recover the data. Set the jumper to the correct position. Erase the drive and format it 3 times.
And so. There is some kind of Linux (in the last resort) program that recovers data by scanning all sectors (without looking at the partition table).

I manually restored a completely erased partition table to a friend (at first he had some kind of virus there, then playful pens and recovery programs) using WinHex (it has a wonderful disk editing mode). In your case, everything is simple - find the MBR, use the appropriate template in WinHEX and enter the correct number of sectors in the section in the field in a beautiful plate.

Googled a little, the forums speak well of TestDisk (OpenSource): www.cgsecurity.org/wiki/TestDisk
TestDisk can
Fix partition table, recover deleted partition
Recover FAT32 boot sector from its backup
Rebuild FAT12/FAT16/FAT32 boot sector
Fix FAT tables
Rebuild NTFS boot sector
Recover NTFS boot sector from its backup
Fix MFT using MFT mirror
Locate ext2/ext3/ext4 Backup SuperBlock
Undelete files from FAT, exFAT, NTFS and ext2 filesystem
Copy files from deleted FAT, exFAT, NTFS and ext2/ext3/ext4 partitions .
I have not used it myself, but if nothing is advised, then you can take a chance.

I restored Acronis, there is an item "Partition Recovery".

Thanks to all!
Just in case, I made a disk image using paragon backup & recovery.
It was not possible to restore the partitions, the monsters from Acronis and Paragon could not do a damn thing.
But GetDataBack helped, which, without noise and dust, simply showed the entire file structure and made it possible to copy everything that was needed.
