There is no point in formatting it twice; you will just wear it out a little bit more for no reason at all. Format with the FS you will /use/ then tell the installer /not/ to reformat it. Saves time & effort. If you're going to make a LiveUSB with an ISO, then sure, use FAT32, but that's a different kind of install. Takes less space, but it's slower & you can't update it. & an OS without updates is a serious liability. <div class="im"> > 2) I recently did an install of Ubuntu 11.10 on an 8gb flash drive.

In one partition? You are doing something seriously wrong, or adding one hell of a lot of extra apps. A full install of Ubuntu, with all updates & all the optional restricted extras, should take about 3 to 3½ gig. <div class="im"> > 3) I just can't resist: > "I have a dream; that one day all of God's children will be judged by the > content of their character, not by whether they top-post or bottom post." > > :-) </div>Feh.

According to gparted: 7.4gb total space 3.5gb main partition (ext4) 3.9gb extended partition, including 3.9gb linux-swap partition 1gb unallocated space Of the main partition, 2.93gb are used, and 576 mb are unused. That's after applying all current updates. That does leave room to breathe, especially if the swap partition is shrunk to free up more space. My mistake. (Always check your work.) BTW, I don't know why the install program set up a 4gb swap partition. That might be excessive. So, I guess an 8gb device can be used after all. But I was not able to use a 4gb drive, it ran out of space. And note that a FAT formatted partition somewhere on the flash drive would make sharing data with Windows users easier.
