SD card not saving files

I'm using Surface Pro, when i saved the file to the SD card, it reflected in the File Explorer directory. Everything appear normal. However, when I restart my tablet, the file is gone. I lost one whole day's work. Anybody can help??

Re: SD card not saving files

Have you tried and used the SD card in another device to see, if the files are really missing or if it's just Windows on your Surface that's failing to show them?
