Problems Making Live USB Stick with Unetbootin

[newtusmaximus]

Thanks Jerry.
Progress, A) Confirmed that the LL iso has not been corrupted during download i.e a firm base to start from
B) The problems burning a viable  Live DVD  i.e that does not stall during boot up is another matter - the writer I am using is on a desktop HP dc7700 compact with 3 GB ram and dual core\Intel processor  so should be man enough for the job. Also laser "cleaned" and good quality Verbatim +RW media used.  Wondering whether there might be a RAM problem - will do memtest just to check.
C) The problem creating a viable  Live USB i think maybe down to the USB flash pendrive. Will try another one using  terminal as guidance above
D) The aim was to eventually try installing to the USB - having bought a "cheap" 64 GB model.  This might be a doctored smaller flash drive to give a greater capacity and it is the "hacking" that is giving the problem.  Currently testing  its "True" capacity - it has been suggested that it might be a "U drive" and not a true Flash - whatever that difference is?
