I have a 2gb SDcard, used an old card reader to view it on my Macbook, which reported it damaged, and formatted it to 1gb. Awww! Now it only has 1gb capacity, but I can see the other 900mb as unpartitioned in windows disk mangement, but it's just too primitive to let me merge the partitions or in fact do anything! Anyone know a method of formatting it back to 2gb?! Thanks!
