 If your usb device is more than 400MB in size, the above command will leave the remaining space unused. To verify it, execute the command:  
 </p>  
 <p class="newcode" style="margin-left: 0;">fdisk -l /dev/<font color="Green">sdc</font></p>  
 <p style="margin-left: 0;">You should get something similar to this:</p>

574    If your usb device is more than 450MB in size, the above procedure will leave the remaining space unused. To verify it, execute the command:

577    <p style="margin-left: 0;">You should get something similar to this:</p>
