Windows 7: Windows no longer detecting SD card

Windows no longer detecting SD card

I just took the SD card out of my camera, and put it in the card slot of my laptop, like I always do, and for some reason this time Windows can't detect it.

I tried rebooting, which didn't help. I also tried putting the slot into another laptop running Windows 7, and it detected the card just fine. I'm not using a card reader - just putting the card directly into the slot. This is the first time I've had any trouble with it.

Welcome to the forums.

The card slot might just have some dust in it, or the contacts are dirty. Try blowing into it forcefully, or use a can of compressed air to blow it out and see if that helps.

You can also open Device Manager and look for the SD card reader and see if it has any issues, like a yellow triangle next to it. If so, post back and we'll see what we can do.

My laptop is fussy about SD cards, too. I have to wiggle my SD card to get it to detect it. That's usually caused by worn contacts.

Please remember one thing:

When a new laptop is purchased, there is always a dummy card plugged into the card slot to protect against dust.

You must either have a card plugged into the slot always or remember to plug in the dummy card when the slot is not in use.

That way you never need to worry about dust.

Thanks for your help! I just checked my device manager and there is a little yellow triangle next to that drive. When I look under properties the device status says "This device cannot start. (Code 10)". I tried disabling it and enabling it again, and that doesn't seem to have helped.

Any ideas on what to try next?
