Card Not Detected by Computer

I have a Sandisk Ultra Class 10 16gb and 32gb that my card reader is not detecting. When they are in my DSLR Camera they work just fine but when I try to read them on my computer nothing happens. I have another 16gb that is read just fine so it does not seem to be the reader. I have windows 7. 

:smiley:     Hi RAI1028,

Dear member of SanDisk Community, welcome.

Perhaps, if the cards, were formatted in the camera, then, are not detected by the PC.

But, please, try the cards in a laptop, directly to your port-card, and see what happens.

Luck, and then you tell us, what happened, please.

Dear member of SanDisk Community, welcome (1) .

Please, do not grieve more.

Contact _ SanDisk Technical Support _ who will replace the device, if it’s authentic and is within warranty.
