when I stick my micro sd card into my pc nothing happens it isnt even seen in MY COMPUTER Ive tried various sd type holders and different usb ports but still no joy. I have three cards two dont work but one works fine suggesting card readers and usb ports work ok Has anyone got any ideas thanks in advance
Is it microSDHC? Because if it is, then it is most likely that you don't have a SDHC reader. Or, it could be that if your reader doesn't work, it could show up as undetected.
Cards that aren't even seen when others are in various readers means they are kaputt m8. That's it - no solution I'm afraid.
