The booklet that came with my Blackberry Curve 8520 says that I can use a micro SD card, but I have only been able to find micro SDHC cards. What is the difference between the two, and can I use a micro SDHC card in my Blackberry?

I have a Canon SD1400IS and I have a 2gb SD card which isn’t enough recording for me. I was thinking about buying a 32GB sd card but don’t know if the camera will support it.

Will it?

Well i bought my SD card thinking it was a normal one and it worked fine on my camera, but it doesn’t even come up on my laptop. Is there anything i can download to make it work? HELP

I have one SDHC card and a digital camera and a camcorder. I’m just wondering can I format the card on both. I don’t want to try it yet until i’m sure, because then it would delete all my photos off the card.

how do i get windows 7 to have a popup menu open when i put in my sdhc card?
is there a driver i can use? if so, where can i download this?
i have a 4gb sdhc card from gigaware.

when ever i insert the memory card into the Lexar JumpDrive Trio and try to transfer pictures from camera to PC, it makes my computer crash. Why?

just wanted to know what the difference was
