You'll need to reconfigure the boot process to tell it to use the new disk. "info grub" or just poke about in /etc/grub.conf. Then you'll eventually need to poke some more because the after the old drive is removed the new drive will be the first drive. For safety, and maybe necessity, you'll want a boot floppy or 3. Also get toms root boot from toms.net. To make a boot floppy. dd if=/boot/vmlinuz of=/dev/fd0 bs=512; # or /boot/<whateveryourkernelis> (remove and replace floppy) cmp /boot/vmlinuz /dev/fd0; # verify, should get an EOF on vmlinuz rdev /dev/fd0 /dev/hda1; # or /dev/<myrootpartition>, see what "mount" says is "/" rdev -R /dev/fd0 1 You'll want several floppys mounting different partitions as root. You'll have two, one on the new and one on the old disk, and they'll move about as you add or delete drives. Make sure they work before you muck about too much. You'll also have issues with /etc/fstab as drive names change. Learn to use single user mode "telinit 1", or when booting: <kernelname> single (Although you wind up here anyhow when things break.)
