I have a problem to write data to external microSD card mounted to my Tab 7.7. I cannot copy/move files, create folders, etc. there when doing this using the Tab. At the same time I can do all of this from my PC when the Tab is connected to it - I can create folders on the microSD, copy or move file. Also, there is no problem to read data form the external card by the Tab (books, for example). So, the problem seems to be only with writing to the card from the Tab.
Could anyone give an advice please? Thank you.
