I have a generic Allwinner tablet running Kitkat 4.4. The internal memory on the tablet is 32GB. 16GB is labelled "internal storage". The other 16GB is labelled "inner SD card".FTAOD, this isn't a physical/ removable SD card. Seems to be some kind of logical partition in the internal memory. By mistake I unmounted the inner SD card. I actually wanted to unmount the external (i.e. removable) SD card. The option to mount the inner card is now greyed-out (In Settings/Storage). How can I mount the inner card? Any help greatly appreciated.
