Can't work on Samsung Galaxy Tab 7.7?

Hi there, the apps can’t show my micro sd card and only internal memory can be seen…when i click inside the internal memory, it includes both files from the internal memory and the micro sd card…do I need to set up anything??


   Our findings show that now internal memory content is seen, however, all content on the card is seen.

   Please ensure you have formated the card as FAT-32.

yes. it is formatted as FAT32.
No memory card icon is shown, only the internal memory icon there.

I cant make it work on a galaxy tab 10.1
