Windows 10: External Drive USB SD Card Reader Not working

I was merging files together on my SD card, and suddenly the drive stopped letting me interact with it in my file explorer. The drive now shows at having 0 bytes of space, and in the disk management application it says "no media." I have restarted my computer, and I still cannot figure out what is wrong. Any help would be greatly appreciated.

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.

 

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.
