*most people just don't care the sd cards well.
*things that you should care
1. When you remove the sd make sure that the camera is off
2. Don't touch the metal chip or make it dusty
3. When you connect the sd to your computer, copy all sd data to your hard disk. Don't edit or delete the raw data from the sd with the help of computer. You can edit or delete the copied data (it is in the hard disk)
4. You can edit or delete data from sd with your camera when the sd is inside the camera.
5. When you want to format sd, please format with the camera option. Not with computer.
6. Don't edit or delete the predefined folder names of sd with your computer. But you can do anything with the data copied to the harddisk.
7.buy a class 10 sd card for faster performance
***thats all. Please try to format with any camera

Now you know why we suggest buying a number of smaller cards, rather than one big one.

Try to transfer your work to your computer, and then format your card in camera - if that doesn't work, get yourself a couple of 4- or 8GB cards.

Even if you get your 32GB card working again, you can never have too many cards.

Your options are:

1.format the card
2.run chkdsk on the card
3.buy a new card

Which Nikon camera are you using?
Are you sure your Nikon camera can use a 32G card?
Once in your camera did you format the card?

Your memory card is dead. Throw it away and buy a new one. For easy maintenance, buy no more than 8GB. I work professionally with 2GB cards so don't tell me it's not enough.

If you have valuable pictures in your old card, ask help from a computer shop that specializes in data recovery.
