SD Card Reader

Welcome to Ten Forums philnz.


This may be a physical problem rather than a software one. SD cards have a write protect notch on the left edge and a slider to lock or unlock the card.




SD card - Wikipedia

Check yours is unlocked before inserting. Insert it, then remove it carefully. Has the slider moved? if so it is catching on something as you insert it and moving it to the locked position. If not, then your card reader may be faulty. This notch should be detected by a microswitch in the reader, that switch may have failed.

 

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.
