I have an iPod mini advertised at 4GB (after firmware, 3.77GB). It's with me everywhere I go and I believe my PC can boot from USB as the boot sequence stops if my iPod or Zip drive is plugged in. I have 3.7 on a CD and i'm thinking of putting 3.8 on my iPod mini. My main worry is that booting knopppix on it will kill the hard drive. Thx fr any help.
