Hi, for my backups I use a 3TB USB drive (one big ext4 partition) without any problems. Just plug in the cable, mount it and perform the backup. The partition (sdi1) is detected an mountable without any problems:

I already tried latest SystemRescueCD (default and alternate kernel), Knoppix and the Gentoo Admin CD. Nothing, the partition is not available. What's the difference? Why does my kernel find this partition and the other one's do not? It's pretty silly to have a backup drive and cannot access it in question ;-) - Jörg
