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:

[36952.162722] iwlwifi 0000:09:00.0: fail to flush all tx fifo queues

Did you mount it Manually? –  Sepahrad Salour Apr 20 '13 at 11:01
    
Nope. All I did was plug it in. –  Davidos Apr 20 '13 at 12:03

try this commands: 1. mkdir directory 2. mount /dev/sdb ~/directory Feed back the error –  Sepahrad Salour Apr 20 '13 at 12:06
    
When the USB isn't plugged in, I get: mount: special device /dev/sdb does not exist When it is plugged in, I get: mount: no medium found on /dev/sdb –  Davidos Apr 20 '13 at 12:59

First you must plug your USB after. sorry try 1. mount /dev/sdb1 ~/directory ... I forgot to write 1 . test it and feed back here –  Sepahrad Salour Apr 20 '13 at 13:04

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

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