TYS 0x03 - I fatfinger deleted my cute little puppy!

This post is part of the Test Your Skills series. You can find an introduction here. And an overview of all TYS’s currently available is over here.


Scenario

Bob, who has a very cute little puppy, sends you an email asking for your help. He says that he, by accident, deleted the best picture he had of his cute little puppy from a USB memory stick. He also mentioned that he immediately unplugged the memory stick once he noticed that he deleted the picture. He took an image of the stick with DD and attached it to the email.

His last line in the mail is something like: This is really important to me. I need this picture back asap. I will make up to you if you can deliver within 72 hours!

Challenge

You heard Bob! Go ahead and figure out if there is a way to recover the picture of his little puppy from the stick image.
Keep in mind: Nothing is like it seems. There has to be a reason why Bob wants this picture back so badly and why it has to happen so quickly. I leave it to you what you make out of that!
