[Q] Phone Storage Missing and Unaccessible

Hi,

My Galaxy Note N7000 have some issue. I hope I can get some answers:

I recently took photos with Camera Apps, and as I got home I want to checked the photos on my gallery apps and it said:
"Not Enough Spaces. Delete Unecessary Items." and then it didn't open. I thought that I have took too much photos but when I checked on Settings my internal memory has disappear. The only thing that shown is my external SD Card.


So I tried to connect my phone to PC but this happened:

I can't get to my internal storage.

FYI, I didn't root my phone. All apps are working fine. I have apps that installed to external storage.

So, I tried to flash it via odin, hoping that my files are still intact (I don't want to lose the files) And no luck either. I have wiped the cache, no luck either. On My Files apps, it says "No SD card inserted"

Can anyone give me a solution for this? I don't want to lose the files. I want to back it up but I can't get access to internal storage.

Thanks in advance.
