Live CDs should work on machines that don't even have hard drives, so just try another distro's live cd and see if your hardware likes that better. If a few different LiveCDs fail, then it could be a firmware/hardware level problem with that machine. If it did shred your USB drive, then it won't mount until after it's reformated because you overwrote the partition table.
