Ok. So my main Windows XP install on my main work rig finally collapsed upon itself, and in the mean time I need something to use until I get everything backed up so I can reinstall the OS (Yes, I'm going to reinstall Windows, don't hate me... I have my reasons ).

So what I want to do is boot a LiveCD (Right now I'm using 8.10), and save my session onto a USB flashdrive. Call is persistence if you will. I've seen several guides on how to formate the drive and label it casper-rw and use the 'persistent' kernel option and everything else, but it never seems to work.

I don't want to make a bootable install of Ubuntu on the flash drive. Just a place to back up changes from the live session. Any help, idea, etc. will be appreciated.

And yes, I've already seen this page countless times:
