How do I copy music onto my memory card?

I can't copy data to my memory card.?

• I'm trying copy music to my TransFlash (SanDisk) memory card for my phone. I have a memory card reader on my new computer. I've done it once before, but now whenever I try to copy music to the memory card, it says it's write-protected. It didn't happen last time; I was able to copy music okay.

• Answer:

  There might be a little lock switch somewhere on the card. I had the same thing to me happen on a USB one and it drove me bonkers. Lo and behold there was a tiny lock switch on it to write protect it.
