I'll admit we have never done this with SCSI drives. We have been doing
it sucessfully for years with IDE drives of all different sizes. Large
drives to small, etc. As long as the partition you are copying from the
large drive fits on the smaller one, our experience has shown everything
to be OK (even though DD eventually bails with an error at the end of
the smaller drive).
Be aware, however, that we have seen disk tools like fdisk and etc will
have problems with the new drive if the the sizes of the originals were
not exact.
Our goal has been to clone drives for turn-key systems, not to set up
development machines or whatnot.
