Recover your deleted jpeg pictures from filesystem or camera memory card - recoverjpeg

Deleted or lost files can usually be recovered from failed or formatted drives and partitions, CD-ROMs and memory cards using the free software available in the Ubuntu repositories. The data is recoverable because the information is not immediately removed from the disk.

Recoverjpeg tries to identify jpeg pictures from a filesystem image. To achieve this goal, it scans the filesystem image and looks for  a  jpeg structure at blocks starting at 512 bytes boundaries.

Salvaged   jpeg   pictures   are  stored  by  default  under  the  name imageXXXXX.jpg where XXXXX is a five digit number starting at zero.  If there  are more than 100,000 recovered pictures, recoverjpeg will start using six figures numbers and more as soon as needed, but  the  100,000 first  ones will use a five figures number. Options -f and -i can over‐ride this behavior.

Installation:
Open the terminal and type following command to install recoverjpeg: sudo apt-get install recoverjpeg

Using recoverjpeg:
Open up the terminal and move to direcotory where you want to store the recovered jpef file and give the following command: sudo recoverjpeg /dev/sda1

Check recoverjpeg man pages to know more options using command: man recoverjpeg


Recoverjpeg does not include a complete jpeg parser. You  may  need  to use  sort-pictures afterwards to identify bogus pictures. Some pictures may be corrupted but have a correct structure; in this case, the  image may be garbled. There is no automated way to detect those pictures with a 100% success rate.
