So suddenly I find that the 4gb Micro SD Card I'm using has write protection. I haven't done anything to it, it appears the write protection fairies have done it.
I'm having massive problems trying to remove it. I do not have the adapter to plug the Micro SD Card into - I'm curious as to why that seems to be necessary as the write protection fairies didn't seem to need it when they turned it on.
It doesn't really matter a hell of a lot as I've order a bigger card that comes with the adapter but still, just for peace of mind's sake.
