Hi,

I remember a while back that people were recommending a pc app for reformatting sd cards that were no longer recognised... My no name 256 card has stopped being visible on my 2x, although it still works fine in windows and OSX. Can anyone remember / recommend some freeware app for a low level format - I am hoping this will save the card ?
 
dd if=/dev/zero of=/dev/hdX bs=1048576 count=64M

where hdX is the device for your sdcard and count is the size of your sdcard in bytes

Thanks :huh: I'm guessing that this is a unix terminal command ? Could you give me a step-by-step starting with open the terminal app ? I don't know anything about terminal :lol: please :(
have you got linux?, then just open a terminal and copy-paste the command in it.

else, you could try mkdosfs for windows:
