I managed to transfer about 25GB of .mpg (video) files to the card and then when I added more the files started or became disappearing damaged. Sometimes whole folders are gone. It didn't matter whether I transferred to my tablet via USB cable or used an SD adapter on my main computer. The card was wrong. I bought a different brand card and had no problems.
