What I did:
- I deleted partition thru os installed but did not format
- I run search, didnt saw my partition, did deep search and saw my parition there that was labled correctly "Mechanik" which was 1TB size (correct)
- pick it as L and hit "write", rebooted

I probably pick wrong source of table (there was backup or org) because there were error about them being different

Now I have partition "Reserved by system (D:)" which is correct size but dont contains my data.

When I run testdisk search/deepserach I cannot see my partition that was labeled.

This is my disk:
Disk /dev/sdb - 1000 GB / 931 GiB - SAMSUNG HD103SJ
CHS 121601 255 63 - sector size=512


When entering into Rebuild BS I get:
TestDisk 7.2-WIP, Data Recovery Utility, September 2020

Extrapolated boot sector and current boot sector are different.


Any suggestion what can I do now ?

Run TestDisk, Advanced, Boot, RebuildBS, List. If you can see your lost files, choose Write, confirm, Quit and restart your computer.

sorry for late response I was freak out by the issue and handle it in other way.

Im not sure how it was when I was doing it but just in case some lost soul will struggle, testdisk would only show bad size partition, same with files.
When I was listing files some of them were missing. I tried few other tools but most of them (the "free" if was showing parition size correct then it would need to "unlock" premium function).

As a last resort I tried non-free application and was able to somehow read correct parition size - looks like I mess with those tools too much, I overwrite bad MBR and so on (inside RebuildBS)

To be honest I had decent success rate wtih TestDisk but that was not enough of knowleght to be able to use it to recover my partition.

Somehow I end up with 100% intact (can't check crc but im using day even now, so what was lost wasn't important)
