I always clone the whole partition to the /new-disk/target-partition
(I have done this literally dozens of times without any problems). Using
just the following 2 commands archives the complete _*_ source tree:
cd to / directory of the source partition, then
cp -ax * /target-partition
To clone a 3GB partition on the same pc takes about 15 mins and a few mins.
for editing.
Since this is my home pc i don't need to edit everything on the new disk,
just necessary things like fstab for hda-sda and network/interfaces and
/etc/modules if any hardware is different. If the clone uses physically the
identical hardware then its just /etc/fstab.
I started using the Grub boot loader about 4 years ago. It is more
flexible than lilo, with a command line and menu interface. So you can
boot to either the SATA or IDE disks without changing the bios. It just
boots to whatever disk is set in the bios and then you can choose/change
any boot options from the Grub menu right at boot time. If you need any help
with setting up Grub you can email me off list.
If you want to keep Debian on both disks or more than one pc up to date
you can run a proxy server for your Debian package archives so you only
run apt-get and download once for all pc's. The easiest one i found is a
package called "approx". This only saves/serves the packages you download for
your install updates not the whole Debian mirror.
