My Samsung Galaxy Tablet (only 1 year old) is randomly failing to recognize the mounted SD card.

AC Question

Tablet works well, then when the battery is say, below 60%, apps which are stored on the SD card become unavailable. When I check the device, it says "mount SD card". I charge it up overnight. The next day, all is working. What can I do to keep this problem from happening? I have not touched the SD card at all (stays in the device). Thanks.
