Maybe try a different card reader? What size memory card is it? If it is over 2GB, it is SDHC format. Older card readers may not work iwth it.
Likewise, if it is one of the newer 64GB cards, those are SDXC format and your card reader may not be able to handle this new format.

As you can all see there is not a certain answer for this problem. Obviously the problem is on the SunDisk's side and there is no admission for it. They manufactured something that does not function as it should (covering all the areas that it was manufactured for that is), and that is all.
They should replace all these cards but the do not want to.
Don't buy SunDisk, it is simple as that.

Firstly, the 32 microSD card when introduced to Windows will invariably invoke the "Do you want to format" screen. Don't do it. Continue on without formatting and everything will be fine.
I have done some testing on the "unrecognize" issue and have come to some conclusions:
- When used with an adapter device that actually is physically inside the device's frame (computer or mobile, etc.) or very near to it, such as with an SD card adapter or a USB adapter, the card will become unrecognizable within a few hours.
- When used with an adapter device that is connected via a cord where the card is physically away from the device's interior frame, such as with an MP3 player or other USB corded device, the card will do just fine for long periods of time.
From these observations, I can only conclude that this little guy is overheating when it's in proximity to the computer or other mobile device, and somehow shuts itself down. When this happens on a Windows device, the only thing that will fix it is to uninstall the port input device (such as the SD card reader slot) using the Device Manager, and then wait about 10 minutes for the card to cool itself. After this time, reinsert the card adapter and have Windows re-recognize it, no re-boot needed btw. You could probably do some manual cooling to the card to speed up the process, but I haven't tried that.
