so you need to find another solution. In your original post you wrote you created a disk image and copied to somewhere else. How could you do that at all?

I'm on ubuntu live with my usb disk. I've created that image using disk utility. It was saved on another partition of my hard drive.

Just decided to format the partition.
Are there any chance to get back my data from formatted partition?

Disk Image of sda6 (2018-08-11).img

Please tell me how can I extract this .img file to another ntfs partition. It's called sda3.

How I would have made the image:
1-mount sda3:

Code:

mount -t ntfs-3g -o rw /dev/sda6 /mnt

2-check for enough room to create the image:

Code:

df /mnt

3-create the image file:

Code:

ddrescue /dev/sda6 /mnt/bkup6.img

Does this sound like what you did? Was sda3 actually formatted NTFS, and did it have enough freespace to fit a 100GB file? Then you should have been able to proceed as michaelk explained.

If you were the FBI, maybe. Otherwise, no.

You have to have enough free space on the destination filesystem that is bigger than the size of your source which is 100GB.

Have you tried mounting the partition from the live CD yet? Yes but maybe not entirely. testdisk and photorec are two good utilities for data recovery.
