- clone the complete harddrive to the new one. Pay attentention, that the new one must be equal or bigger than the source. - Use another live cd with gparted on it and move or resize the partitions. -------------------- Second way (more work and more complicated): - Boot with a linux live system (debian live, Knoppix whatever) - mount the old one to a new mountpoint in root, like /disk1 - partition the new drive to your needs manually - mount the new one to a new mountpoint in root, like /disk2 - use rsync for transferring data to the new one - reboot to your old system with the connected new harddrive - install grub on the new harddrive (grub --install /dev/sdb or update-grub might do it) -------------------- Have fun Best Hans > I have a btrfs RAID1 system.
