Kobo Touch Mini SD issues
I have a Kobo Touch that was purchased at the beginning of December. Everything is working great with it, and there haven't been any problems. Today, we tried to use a Lexar High-Speed 16 GB Mobile Mini SD card. After loading a couple of .pdfs (my sister's format of choice) we inserted the SD card and did a search. It was able to locate the other applications on the card, but not the .pdfs themselves. Additionally, the card seems to have come with software that is not allowing us to add .pdfs to the card.
I believe that a reformat of the card would solve the issue. However, I do not know what to reformat the card to (as it must be done to ensure that this pre-installed application is completely removed).
I should also note that I am running a Mac, so please be advised.
Thanks in advance for the help!
