Post subject:  Micro SD card pin out

Hi Friends
I have got a 64gb microsd card which is not detected. When I connect it to card reader LED on card reader blinks for a second and goes off.
I think something is short inside .
I want to know how can I check card using multimeter (by checking continuty)

VCC-GND - check resistance.
Card is hot after power on?

I have checked VCC & GND ( pin 4 and 6) they are open ( short) , I think its game over card is non recoverable.

Sometimes not end :) If you have, you can use thermal camera or freezer and check which place is hottest the fastest. And if possible remove short. Such cases are very hard but we have success statistically for ~50% cases.
