How to unmount my SD card in vivo

Solution
Removing the card would be all you need to do. Try taking it out. turn the tablet off, restart the tablet and then try reinstalling the card.

If the tablet won't read the card, then I would test it in another device to see if the card works. If it doesn't, then you need a new card. If it does, then the problem may well be the port on the device.

If that is the case, should it still be under warranty, I would contact the manufacturer. If it isn't under warranty, then try a local tech.
