Can I retrieve files from a USB after format?

Hello,

I bought a TV which allows you to record on to a USB, it said the USB needed formatting so I proceeded.

This was two weeks ago, I've just tried putting my USB into my laptop and the files have gone.

Is there anyway I can retrieve them?

I have used the USB for recording since I formatted the USB.

Any help would be greatly appreciated as there all my travelling photos.

Regards,
James
