Hello everyone,
I have a 16gb N9 but when I connect this device to my computer windows or linux both show me that the memory is only 3.91GB.

I would like to add around 10gb of music but I can't because it windows tell me that the device don't have the space.
How could I 'fix' my N9 so that the hard drive is around 16gb how it normally should be ?

Thank you very much

PS: yes I have installed nitdroid but I don't use it anymore.
