You can see that is says that write-protect is on.
I've already tried:

Looking for a read-only hardware switch
Using Gparted to format the drive. It says that the drive is read-only so it can't write to it
Using dd to overwrite the drive with 0s. It also can't open the device (/dev/sdc) for writing.
Pluging it in to a Windows 7. It too says it's read only

 You can see that is says that write - protect is on. 
 I've already judge: 

 Looking for a read - only hardware switch 
 Using Gparted to format the drive. It say that the drive is read - only so it can't spell to it
