I have downloaded and dd'd a thumb drive with the ubuntu-13.10-server-amd64.iso file (sudo dd if=ubuntu-13.10-server-amd64.iso of=/dev/rdisk3). Unfortunately, after the installation the thumb drive is not writable. chmod-ing the files do not work: the whole disk is viewed as a CD-ROM.

  • Is it possible to make my non-writable USB thumb drive writable?
  • Or are there any switches/flags to dd that would do the trick?
  • Anything else that would do the trick?

can you post output of the "mount" command? maybe the drive is mounted as ro - might as well.. – mail-nv Feb 12 '14 at 12:37

It is not writable, as it contains ISO 9660 filesystem. A separate tool called "Startup Disk Creator" can be used for creating "live USB".

Open System > Administration > Startup Disk Creator, select your .iso and (USB) disk to use, and click Make Startup Disk.
