Things could be a little bit difficult if your memory card is not recognized by the PC. This means that there is something wrong with your card reader or the card is physically damaged. There are two ways to solve this case.

1 - Change the Card Reader

A memory card reader is a device for accessing the data on a memory card. Most card readers also offer the write capability, and together with the card, this can function as a pen drive. If your memory cannot be recognized, change the card reader. Then, try again, to see whether it is deleted or not.

Tips for choosing a card reader:

  • Portability and overall ease of use
  • Supported card types: The more card types the better.
  • Speed: USB 3.0 high-speed transfer rates.
