We use an Adaptec 71605 controller. smartctl -x does not provide any more
useful information, I suppose. I only post the output of one drive as an
example this time. They all give a similar result.
smartctl -x /dev/sdc

What about the state of the software RAID5? It would be great if I
could bring it back to a state where the filesystem on it is fully
working again without having to copy the 20 TB of data to it again
(copying this amount of data takes some time :( ).
