Thanks, that worked.

An interesting note.  While things were running backwards, that
is on /dev/hde the filesystem was very slow.  An operation
that generally ran in about 5 seconds took about a minute.
A large filesystem backup, generally taking about 5 minutes,
took about 45 minutes.

As of reversing things back (/dev/hda) speed is back to normal.

The system only seemed slowed on disk access.
