====== 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) <HTML> <!-- AddThis Button BEGIN --> <a class="addthis_button" href=";username=xa-4beeaaab61b514bf"><img src="" width="125" height="16" alt="Bookmark and Share" style="border:0"/></a><script type="text/javascript" src=""></script> <!-- AddThis Button END --> <br> <br> </HTML> Share this knowledge with your friends!
