Hi Rainer!

Are you sure the controller chip in your SATA/USB enclosure can
deal with more than 2TB of disk?

All such enclosures I have either truncate at 2TB or worse, they wrap
around.  A disk with 3000GB (decimal) will give you just short of
2794GB (binary), and wrapped around 2TB will give you 746GB.

So I am quite sure the controller chip in your enclosure is to blame.
