clip + 16GB sd card not detected

[abitbol]

Hello,

I apologize in advance for my english (I'm French).
I bought a clip + (4GB). I installed Rockbox 3.13 and to my great surprise, my sd card 16gb class 10 is not recognized by RB.
View Disk Info detects my sd card well, but not the file explorer.
I did a CHKDSK and a FSCK on my sd card, there is no error.

Have you an idea of the problem?

Thank you for your help

Is the card detected by the original Sansa firmware? If so, try formatting the card using the player.

My sd card is detected like empty by the original firmware.

EDIT : I formatted the sd card with original firmware but it still not detected by RB

It's works !  with RB  developer's version (9a3400a), my sd card is detected.
Thanks to the developer
