If you own a Samsung Galaxy Tab A (SM-T580) or most likely also the LTE version (SM-T585) and don't care so much about android 7, but rather use your SD-Card as internal storage in android 6 - YOU CAN ! An SD can essentially act as another hard drive for your smartphone – you can move pictures, videos, and even app data there instead of housing it in the device's internal storage.
Once your phone is reset or dead, you may find the SD card inaccessible by any device. Tap Internal storage then navigate to the directory/folder that contains the file (s).
