Can you please attach kernel boot log?  And does the kernel whine
about anything after the failure?

What if you swap the two?  Or is one SATA and the other PATA?  In that
case, can you get a chip sil3152 controller (probably ~10USD) and see
whether it works any better?

This one isn't really related.

This one might or might not.

I suppose the drive is hanging off this one, right?

k3b doesn't really show which command failed.  I suppose it's
WRITE(10).  The failure code is ILLEGAL REQUEST and the ASC/ASCQ are
vendor specific and don't really tell us much detail about the
failure.  :-(

Can you please try wodim with "-pad -v -V" options?  It will generate
a lot of output.  You'll probably want to redirect the output to a
file and watch it using tail or less.

Thanks.
