Windows 10: Why does my SD card no longer read

Tested my Micro SD card from my GoPro to make sure I could transfer images and videos. Put the Micro SD into the adapter, downloaded 1 video, and put card back in my camera. Took a few pictures to mess around about 5 minutes later and tried to transfer those too. This time though, the pop up asking what I want to do with the external device did not pop up, and it never even made the sound notifying me I plugged it in. What is going on?

SD card/SD card reader no longer working

Bradleyb, in your Device Manager do you have anything listed in Storage Controllers? I get an entry for MMC/SD. I just checked a 1GB SD card and a 4GB SDHC card, both worked in File Explorer to show their contents.




Side note: A caveat for such cards is that if they are to be used in a camera they need to be formatted in the camera, not in Windows.

 

SD card/SD card reader no longer working

Hi. New to this so not sure of category.
I have a Lenovo G70. Windows 10, 64bit
My SD card reader has stopped working.
In Device Manager, the SD card is not listed.
I can't format the card as it is not listed.
I cannot locate the card at all as it is not listed anywhere.
I've tried chkdsk and get 'Cannot open volume for direct access'
I don't even have the icon displaying when micro SD card is inserted.
It did work previously but I had errors. Scanning and fixing did not help.
I place the SD card in my Android phone and it works fine.
Please help!
Thank you for any assistance.

Hello,

Thank you for posting your query to Microsoft Community. We understand that you Lumia 640 XL LTE is having issues reading your SD memory card.

There is a possibility that the SD memory card corrupted. Please try to perform a Scan Disk maintenance on it by following the steps below:

• Turn off your phone and remove the SD card. Use a SD card reader and plug it in to your computer.
  
• Open Computer by clicking the Start button, and then clicking Computer.
• Right-click the SD card drive that you want to check, and then click "Properties".
  
• Click the "Tools" tab, and then, under Error-checking, click Check Now.
  
• Put a check mark on the "Automatically fix the file system errors" and "Scan for and attempt recovery of bad sectors".
• Click Start.
  • Wait for the Scan Disk process to complete, then mount your SD memory card back to your phone.

Hope this helps.
