with pleasure, but just leave me a day or two : I'm now copying
data from a 3Ware array with a faling disk to this box (that is
where I set it up for originally) before rebuilding the array
with a new disk (that lab has no money (they say) for decent
backup and I fell more confident to fiddle with twdm2 when
having a decent backup of the data).

Enfin, I'll let you know when I have tested both parts of the
patch individually.
