I have a sony handycam, and it had all my memories on it. I accidentally formated it and it lost all its data.. Can I get it back?
Yes, you can. Just use a data recovery software.
I have ever recovered deleted photos from Olympus camera.
and this guide is useful, maybe you can take a look.
sadly, no. once reformatted, all the files are gone.
go on the computer and plug it in it might work
