I don't think hashing is an issue, since Carl said these are details, with
no paths, but I wonder whether these datasets were erased (or packed) after
extracting the records. If Image is traversing a big delete chain to put
the records, it could be jumping all over the place.

Carl, you did not say what you are converting. If it was a key field,
you may
be impacted by seek time, because the keys are being hashed to different
locations.
