Sandisk Extreme 90mb/s card shows only 31mb available memory!!

Hi , I have been using this card for almost 6 months and now today I plugged it in laptop,

my data is lost and the memory card shows only 31mb available memory.

I tried every possible way to format the card including the dedicated SD Formatter 4.0,but no results.

Is my card eligible for RMA?

Also,something strange I noticed with the card is that heat up a lot after this incidence,I almost thought it will burn.

I even saw some swelling on side opposite to the lock switch.
