I have a SanDisk SDHC "Wake Up Your Phone" micro disk, that I use in my cell phone, with an adapter that fits into the SD slot on two of my printers and my two camera's. My issue is that none of the above will read the SDHC card when I insert it. I took it into the store where I bought it and they could get it to display the pictures that were on it that were taken on my phone. How or what do I need to do in order to be able to get my equipment to read this card? Is the issue that my equipment is older and doesn't see the SDHC card but can read a regular SD card?
