Just dd the whole drive. Saves steps 4-6.

Why?

A problem with having both drives present arises from the way RH has 
been mounting drives by label for years. My early experiences was that 
the wrong filesystem gets mounted.

I think having two of these isn't good, too:
/dev/VolGroup00/LogVol00


Note that the new drive cannot be smaller.
Note that if the new drive is larger, you can use the extra space as new 
partition(s) and/or expand the adjacent partition. If you google my name 
and resize2fs you will find my earlier writings on the subject.
