Hey,

During the Arch installation, somehow my default Linux SSD partition (which is `/dev/sdc`) is changed to my internal 1T HDD's. I always check it with `fdisk -l` all the time before i do a any operation. But I forgot to check it out dev id in the setup process somehow. After I typed the format commands and press the Enter, it was too late. I had to watch formatting process.

What I did:
1. Forgot the check `fdisk -l`
2. Ran the format commands: `mkfs.fat -F32 /dev/sdc1` and `mkfs.ext4 /dev/sdc2` (Why the F that command did not warn me like `hey, this is your internal HDD and 95% full, would you like to continue the format process? ...)
3. In Disk Management, HDD shows as `unallocated`, i can't see HDD in the `Devices and drivers` section either.

I just want to remove FAT32 and Swap partitions and recover as many files as I can. Whole HDD partition must be in NTFS format as used to be.

Run TestDisk, Analyse, Quick Search, Stop, Deeper Search, set the NTFS partition to P(rimary).
On next screen, if the NTFS partition is listed as expected, choose Write, confirm, BckupBS, confirm, Quit and restart your computer.

Hey,

Thank you so much for promt reply. Now my HDD looks like this in Disk Management:

After the restart, i tried to [undelete] my NTFS partition under [advanced] section. But it says: Can't open filesystem. Filesystem seems damaged. (list option didn't work either, throws same error)

Log file: https://paste.ee/p/KuJIC

My HDD is still unaccessible:

I can't see the my primary HDD on the PhotoRec. It shows "Unknown" and "Fat32" partitions only.

I just want to recover as many files as I can before the full format. What should i do as a next step? Thanks...

Use Photorec.
