No idea what BartPE is, but Knoppix is a Linux distro that runs completely from the CD. OH, you'll have to use an external harddrive unless you have two CD burners.
Anyway, yeah Knoppix can read and write FAT32, and can read NTFS, so yeah you will be able to get the data.
Yes, k3b is a Nero clone for Linux.
Actually I like it better. :classic:
Edit: If your computer supports booting from USB, like a USB thumb drive then you can stick knoppix on there, its a PITA to get it to work though, I only got it to work once.
