These things are handy low-level geek tools for those moments when, you know, you've got this machine in pieces for a motherboard upgrade, and you've just realised there's stuff on its drive that you need to access on that machine, and you don't want to shut that machine down and take the side off and unplus one of its drices (because its ATA cables are fully populated, of course) and push the cases together and string a ribbon cable across the gap, or unscrew this machines's drice and sit it on some cardboard in the bottom of that machine's casing, then boot that machine again, just to get those 27 kilobytes of data.
