The external SDCard was detected by my tablet, but it doesn't get mounted. I looked it up with my file browser and found the sd card. But when I open it, it says "empty".
I restart/reboot the device, but it does the same again. I have also tried to format the card as Fat32, NTFS and Others but it's not working.
The camera says "Media Scanning", which to me looks as it would have trouble accessing the card as well.
