Sorry if these questions are answered elsewhere, but I tried searching without any luck. So two questions:

1. My memory card is being set to read-only. What do I need to do to enable write access?
2. I have no problem re-formatting my memory card, so if I do what file-system do you suggest? fat32, extX, etc

FYI, it is a 16Gb Sandisk card
