Sandisk Extreme SD Card 16GB Not recognised

Not sure if this is right place to post. I bought a Sandisk Extreme SD Card 16GB and have been using it with my Nikon camera for still pictures. I tried transferring the photos to my Windows 10 Notebook but despite repeated tries, the card was not recognised.

I have not problem with a SanDisk 1GB SD Card.

what may be problem?

Try some trial versions of recovery softwares (ex.: Easeus, R-Studio) to proof that the card is readable or not. If yes, you can pay for the software’s full version. If not, try Googling for a data recovery company in your surroundings who work with the chip-off recovery method. It have costs (especially for monoliths, like mini and micro SD cards), but this is the only way to bring back the valuable memories.

First of all, you should ensure the SD card is well connected.
In detail, you can do these things

  • Gently wipe the metal contacts of the SD card with a dry and clean cloth.
  • Dusting the slot of SD card reader or adapter, or simply replace it.
  • Use another USB port on your computer to connect the SD card adapter.

Secondly, you may have to go into the Windows Control Panel, Devices, and uninstall the SD Card Reader, and then reinstall it. I had that issue with a previous computer, and I believe it has something to do with doing a manual disconnect (safely eject?) before you physically remove the card.

If your SD card still not recognized or showing on your Windows PC, here are a number of ways to get your laptop reading sd cards: https://iboysoft.com/data-recovery/sd-card-not-showing-up.html
