How do you?

How do you format a micro sd card 4gb when i reformat it, it says unable to format does any1 know how to fix the problem

If you can't reformat it, and you can't acess the contents of the micro SD, it means it damaged beyond help.

sounds like you're going to have to get a new micro SD

Totally, my cousins friend had the same problem...

this time i bought a new micro sd card its kingston 4gb and im using a micro sd usb 2.0 and i still can't reformat it i think its the usb fault for some reason

Prehaps the connector is at fault, or your using dodgy sd cards.What is the name of the shop?I'd stay away from places that sell cheap memory cards, the cheaper the riskier unless it's like jb-hi fi in australia, cheap enough but well known.

try panasonic formater maybe it will format your sd cardhttp://panasonic.jp/support/global/cs/sd/download/index.html
