[SOLVED] mount: /dev/sdc1 is write-protected, mounting read-only Why?

I don't expect you guys to answer this question in the time I need the answer. My wife and I are going out of town early tomorrow. She asked me to add a new CD that I have acquired to the thumb drive that feeds her car radio. I've always just plugged the drive into my desktop and mounted it and gone on copying tracks. It's always "just worked". Now it's not. Now it gives me the error you see in the subject line of this post. I don't understand why this is happening. The drive is write protected, so the system is mounting it read-only. I get that. But how do I change it if it's mounted read-only? Is there some switch I can pass to mount that will make my drive writable again? The fstype is vfat, if that matters....
