Chosen Solution
Yesterday I noticed that one of the albums in my libraries weren’t there on my phone, so I plugged it into my computer to see if it’s there. But it looks like I mistakenly deleted some important pictures from my SD card. I need to get them back now! Please help!
Try Recuva. http://www.piriform.com/recuva
First of all DO NOT keep using your SD card, unmount and remove it immediately. If you keep using the sd card the data may be overwritten. Use a microsd adapter to plug in the card directly to your PC. Download and install Recuva and run a scan on the microsd card. If any files are found the program should be able to recover them
