Lumia 1520 :: Why Phone Show That SD Card Not Found When Inserted

Purchased a new SD card by Transcend 32G. It could not be found in the phone when inserted. I formatted the card on my PC after these failings, readily recognized there....and did a quick format and a soft reset, as well as a Hard Reset. Still the phone would not recognize the Card. More Reading. Back to the PC did a "slow" Format, turned off the phone and did a hard reset. At the large exclamation point I inserted the SD card and pushed the series of buttons to begin the "turning on of the phone". In my earlier formats and resets I didn't attempt to install the card until after the reset had been completed. My thinking in the last instance was "maybe" the phone would re-format the card.
