Puppy Linux doesn't require the kind of liposuction required by the meatier operating systems in the Hive Five in order to fit into a nice portable package. Weighing in at under 100MB, it can easily be loaded on everything from a CD to a USB drive with little fuss. The user interface is friendly even for a non-Linux user, and the basic tools you need for partitioning and file recovery are readily available—although it's just as great for web browsing and basic computing.
Slax takes a very user friendly and novel approach to portable computing. Before you even download the distribution you can customise it right from the download site by adding and subtracting modules based on your needs. You don't need the office software? Delete the module. Can't live without multimedia tools? Add them in. If you're completely new to Linux and setting up a portable operating system, Slax will get you up and running with the tools you want in no time flat.
The qualities that make Ubuntu so popular as a desktop operating system and live cd, give it a lot of weight as a portable operating system. Ubuntu isn't as small as some of the other contenders here but thanks to a number of factors, including strong saturation in the Linux market and an easy to use tool built right for flash-drive installations, Ubuntu makes a great addition to your portable drive.
If BackTrack was your friend, it would be the friend you have who keeps a survival kit in an Altoids tin, a length of rope in his jacket just in case, and a folding shovel in his briefcase. BackTrack isn't the most lightweight and certainly not the fluffiest portable operating system in this Hive Five. BackTrack is a serious tool packed with 300 applications covering everything from packet sniffing to hot spot probing to brute force password attacks. If you know what you're doing BackTrack will leave no corner of your computer and network un-poked, scanned, prodded, and analysed.
CrunchBang is a fork off the Ubuntu development tree. CrunchBang sports an ultra-minimal interface and has heavy emphasis on media playback. Right out of the box Firefox has Flash support and VLC can play a variety of media including DVDs. If you're missing an application or tool, thanks to its Ubuntu roots you can grab software right from the Ubuntu repository.
Damn Small Linux is in fact really damn small. How small? Originally designed as an experiment to see how much Linux awesomeness could be packed into 50MB business card CD, Damn Small Linux hasn't strayed from its origins as an absolutely tiny portable distribution. Just because Damn Small Linux is tiny doesn't mean it's underpowered. It includes Firefox, a VNC viewer, file managers, instant messaging clients, and even a web server.
