yes

It is existing. But possible it may have legitamatly failed. Here is a log
generated today when I
tried to add it back into the array.

Does all of this suggest a complete and total drive failure? :-) I orginally
built this md4 array
as a Raid 5 from three of the cheepest drives that I could find (Maxtors).
Then a couple of
months later, one drive died. So I converted the remaining to into a raid 1.
Now this one seems
to have died. I guess I am learning my leason about buying cheep hardware.
Fortunately I have a
back-up of everything on this array.
