I got a new hard drive to replace the too-small older one, and they both
have essentially the same OS (SL 4.2) on them, and the same filesystem
type (ext3). The old HD was put in a removable rack tray, and shows up
as hdd (the new is hdb, and the CD-burner is hdc).

But the only partition I can see is hdd1, which shows the old /boot; how-
ever hdd2, which I expect is the old / shows nothing at all. Do I need
to mount it, even tho it's already ext3? Should have tried this before.

What does "fdisk -l" say about your drives? You may have to mount it by
hand: automounting partitions for you is begging for trouble, so I'm not
aware of any OS doing it for other hard drives.

Here's the output I get from 'fdisk -l':

'hda' is the first fixed HD, on which my OS/2 system sits, 'hdb' is the
second fixed HD holding the newly installed SciLinux, and 'hdd' is the
old HD now put in as a removable disk. What puzzles me is that before
being supplanted by the bigger new disk, 'hdd' had the same three parti-
tions as the new 'hdb'. Yet only 'hdd1', which is the '/boot' partition,
is as expected, and readable. There was one difference between 'hdd' and
'hdb': in 'hdd' the sequence was /boot, /, swap, rather than the sequence
in 'hdb' of /boot, swap, /. I wonder if that could be a contributing
factor.
