Recover EXT4 partition

Question

I was trying to resize my EXT4 partition and something went wrong. I lost it. The space in once consumed is now being represented as Unallocated. How do I recover the partition?

Solution

Well provided you haven't overwritten it, it's possible.

sudo apt-get install testdisk
sudo testdisk

Note to self: I personally had much more success with gdisk than testdisk.
