Is there any way to restore EXT4 partition

Question

Is there any way to restore ext4 partition after formatting the entire hard disk then making two partitions of NTFS

Solution 1

Testdisk supports ext4. The example uses ntfs but you should be able to apply it to any file system.

Solution 2

Odds are against you on this one. The new partitions more than likely overwrote the previous partition tables.

However if you're just looking to recover files from the previous partitions and haven't copied any data onto the new partitions, you should still be easily able to retrieve most of your files, then repartition it back and copy the recovered data onto the partitions.

If you need further assistance, let me know and I can detail the steps for you.
