Windows 10: SD card reader and SD card not showing up on Windows10 at all

Hi,I have an internal SD card reader, which I know works because it works on my dual-boot Linux.If I insert an SD card it does not show up on Windows10 at all - I cannot find it in the FileExplorer, DeviceManagement, PartitionManager, or with command prompt using diskpart. This thus also does not allow me to update or reinstall drivers for the SD card reader, as it just doesn't show up anywhere.I can read and use the SD card normally using a USB port with a little SD to USB conversion.What do I have to do to enable my SD card reader on Windows again?Best,GMS

:)

 

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.

Right click Start > Device Manager > View > Show hidden devices > USB controllers > Realtek USB 2.0 Card Reader.
That is where mine is, only becomes unhidden with an SD Card in.

Not all SD cards have good contacts and/or the SD Reader contacts. I clean them with a small piece of card dampened with alcohol, IPA etc.
