If you use the PC, just go to my computer, find the card, right click it and then format. If you do it from the DEVICE you have a app in programs that will delete and format the card as well....hope this helps and goodluck!
took the words right from my mouth.... cards will need to be reformatted from time to time...... what i do is i update the files in a folder on my desktop called storage card once a week and back the files up there and than transfer from there to my external hard drive so i never lose my important cabs and skins.
