How to recover deleted files from an SD card

It has happened to me a couple of times that I have accidentally deleted a group of photos since in the contextual menu of Thunar, "Delete" is very close to "Copy" and the application is not very questionable; directly delete. Not to despair, here is the solution.

The first thing is that immediately after deleting the files, DO NOT copy anything to the SD memory.

Installation

First you have to download testdisk either by doing apt-get install testdisk or pacman -S testdisk.

Create an image

From the command line, we create a disk image of our SD card. We must have enough disk space to do it.

dd if = / dev / DEVICE of = memory_card.img bs = 512

Where DEVICE is the SD card reader. In my case it is mmcblk0.

This is obtained by doing:

sudo fdisk-l

We will get something like this:

Disk / dev / mmcblk0: 3965 MB, 3965190144 bytes
49 heads, 48 ​​sectors / track, 3292 cylinders, 7744512 sectors in total
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical / physical): 512 bytes / 512 bytes
I / O size (minimum / optimal): 512 bytes / 512 bytes
Disk ID: 0x00000000

Recover files

In a terminal we write:

photorec memory_card.img

The application is quite simple to use and the utility gives the option to recover all the files, but does not recover them with the original names. Also, the most important thing is that they can recover the files.
