Couldn't access my Sandisk Ultra 32 gb

My card suddenly stop responding . My android device says “The card is empty or Unsupported card”. What should I do??? Help me out…

Back up your data, format the card on a Windows 7 computer and the card could be fixed.

Use the slow one, do not select “fast format”.

BIN IT, THE PRODUCT IS JUNK

I smell a troll. :angry:
