Odd. If you can see one partition you ought to be able to see them
all. What happens if you (as root) run "fdisk -l /dev/..." against the
external drive? And are the appropriate device files being created,
e.g. /dev/sda1, /dev/sda2, etc.
Is your system using the swap partition on the external drive ("cat
/proc/swaps")? If so you may wish to prevent it, as it is a
hot-plugable drive.
I do a similar operation annually. What I do is mount my old /dev/hda
as /dev/hdc, and leave it in place for a year. I set all the
partitions on the old drive to ro in /etc/fstab, e.g.:
/dev/hdc3 /mnt/oldsys ext3 owner,ro 1 2
The main gotcha is you must be careful with the partition labels so
that you don't get duplicates, e.g. two /home partitions.
