I have a micro sd HC card. I need to put it in video camera that uses full size SD cards. I could use an adaptor. On my adaptor, it says micro sd but not micro sd HC and my card is HC one. Will it work?
Actually most normal card reader's are not able to read HC SD card, so its hard to tell for sure. You can try, it wont damage the card.
The adapter is passive, its just brings out the microsd's dense packed contacts to the more spread out SD format. It will work fine. I just used an ancient adapter to read my sdxc card.
