 +====== Copying a live USB key / stick ======
  
 +
 +So you have a live USB stick that you want to make a copy of. Well good for you!
 +
 +Put it in and do the following check procedure.
 +
 +df -h
 +
 +You should get a message returned looking something like this:
 +<​code>​
 +Filesystem ​           Size  Used Avail Use% Mounted on
 +/​dev/​sda1 ​             36G   ​34G ​ 197M 100% /
 +varrun ​               248M  120K  248M   1% /var/run
 +varlock ​              ​248M ​    ​0 ​ 248M   0% /var/lock
 +udev                  248M   ​96K ​ 248M   1% /dev
 +devshm ​               248M     ​0 ​ 248M   0% /dev/shm
 +lrm                   ​248M ​  ​34M ​ 214M  14% /​lib/​modules/​2.6.22-16-generic/​volatile
 +/​dev/​sdb1 ​            ​299G ​ 277G   ​22G ​ 93% /​media/​LACIE
 +/​dev/​sdc2 ​            ​1,​1G ​  ​65M ​ 963M   7% /​media/​casper-rw
 +/​dev/​sdc1 ​            ​799M ​ 702M   ​56M ​ 93% /​media/​kubuntu810
 +</​code>​
 +
 +It is the two last we have an interest in as these represent the live distro, try doing the df -h without having the stick mounted if you don't know the names of the mountpoints.
 +
 +Now unmount the USB stick.
 +
 +===== Copy the live USB stick to an ISO =====
 +
 +Once unmounted you are going to use the infamous dd command ( DO NOT DO THIS UNLESS YOU ARE ABSOLUTELY CERTAIN WHAT YOU ARE DOING AS YOU CAN WREAK HAVOC WITH YOUR SYSTEM IF YOU MESS UP, DOUBLE CHECK AND TRIPLE CHECK EVERY DD COMMAND YOU MAKE!!! )
 +
 +Got that ? Okay now type:
 +
 +sudo dd if=/dev/sdc of=/​media/​LACIE/​sorted/​own/​isos/​kubuntu810.usb.iso
 +
 +Once you launch the above command you will get a message saying.
 +
 +[sudo] password for YOUR USER NAME:
 +
 +YOUR USER NAME=the name of the currently logged in user.
 +
 +You type the password and wait, after a while something like the below text should appear in your CLI
 +<​code>​
 +3915776+0 records in
 +3915776+0 records out
 +2004877312 bytes (2,0 GB) copied, 130,009 seconds, 15,4 MB/s
 +</​code>​
 +If that happens you have successfully copied the contents of the live USB to your harddrive.
 +
 +===== Copying the ISO to a USB stick =====
 +
 +Getting it back onto another stick is a relatively simple affair simply type the following:
 +
 +sudo dd if=kubuntu810.usb.iso /dev/THE NAME OF THE USB STICK 
 +
 +And voila you have a live Kubuntu distro on a stick (or whatever live distro you choose)
