I accidentally entered an erroneous command to copy everything from the old HD to the new one and ended up corrupting the OS. However, the *first* thing that happened was that command zapped my Data.fs. It was located on the new HD with a symlink for the entire var dir going from the old HD to the new one. 

This is very easy to do: copying a file to an (existing) destination
opens and truncates the destination. When the destination happens
to be equal to the source, the source is truncated as well -- and you have
lost your data.
