Now, I try to reconstruct /dev/wd1d (the failed drive):

Thanks,

Has your raid0.conf file changed? The one you posted earlier shows
that /dev/wd1d
*is* a component of that array.
It has not changed. Here it is:
<snip>
Thinking about this some more, I suspect that what may be happening is
that
the disk still thinks it is a spare. Try blowing away the RAID
partition,
possibly even replace it with a regular partition and write data to it
just
to make sure. Then delete that, recreate the RAID partition and try
again to
reconstruct the component.
(It may also be possible to achieve this with the -r option to raidctl,
but
I'm unfamiliar with the operation of this switch).
Essentially, you configured the disk as a spare, now you want to
override
that configuration and configure it as a component.
The man page does say that the spare and the component it was
reconstructed
from are interchangeable, but I think the system is getting confused as
to
just what wd1d is.
Taking a different approach, you could keep wd1d as the spare, but add
a 3rd
disk to replace the failed component and simply reconstruct onto that
(using
the -B switch to raidctl)
Also - dont forget about the syslog.
