Hey there, mona24.

It sounds like there's some sort of issue with your card. I'd recommend that you try accessing it via Linux Live CD/USB, to see if it is properly recognized and if you can get to your data, or try some of the data recovery programs from this thread: http/www.tomshardware.co.uk/forum/id-1644496/lost-data-recovery.html
If your phone is recognizing some of the files, I'd recommend that you connect the phone to your computer and back them up if you can.

Hope that helps.
