I have a usb with a hidden cdfs partition that I want to purge, but when I plug it into my linux box, it doesn't register. fdisk -l only shows my hard drives, and the usb doesn't auto-mount. I pulled the USB out, plugged it in and ran dmesg to get the following lines:

From your dmesg output, the USB stick is seen as a read-only device.

Please, see USB memory stick presents as two storage devices.
