Retrieve deleted file from usb?

You may try asoftech photo recovery which helped me before. You can download trial for free http://www.asoftech.com/apr.

It happened to me once because I filled the usb drive to the limit and had to format it and unfortunately I lost everything on the drive. Maybe you should try to find a way to back up the usb drive and that's going to be hard as you cannot even open it. Try to find a way online.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
