Ext2 or ext4 without a journal are the only ones to use on a flash drive, as using one with a journal will wear out the drive. Removing the journal from an ext4 filesystem is quite hard IIRC, so ext2 is the easiest way to go. Bruce is right about sudo, you also need a space before the first slash. <blockquote type="cite">On Dec 27, 2009 2:19 PM, "Bruce MacArthur" <<a href="mailto:bmacasuru@fastmail.us">bmacasuru@fastmail.us</a>> wrote: On Saturday 26 December 2009 01:19:04 pm Gilan-Schah wrote: > I have installed Kubuntu a week ago. I...Hello, Gilan -- I think that the command is "sudo" -- rather than "sudu". Also, I seriously question the wisdom of using ext2; ext3 or ext4 is much more appropriate today. I am reasonably sure that the command is incomplete as you present it here because it lacks a format parameter. Sorry -- I do not have time right now to research the correct form of the command for you.
