Try reformating the card. If that doesn't work return it. Two possiblities I can think of:
1.) It is a valid card with a problem. The store you purchased it from should be glad to replace it.
2.) It has been modified to either look like a 2G card, and/or is a smaller format card that has had compression sofware put on it and is now having problems. I seen a number of cards & USB sticks, that are counterfeit supposedly from many reputaple vendors. They usually die between 500M & 1G after a few uses or on the first use.
I recently bought a Sandisk 2gb mini-SD card and I've begun to copy my mp3's into the card via a card reader. I also have copied music through my windows mobile smartphone sync up through a USB cable.
For some reason, I can only copy up to 700MB and whenever I try to add more, I get an error message saying,"The directory or file cannot be created."
So is there a way to break through this problem?
I need help and many thanks.
