Real old ATA (4.x) showed them and when they left in preATAng there was lots of complaining. I see that now we are back to the old (initial) behavior complains are showing up again :/ There are problems like what to do with disks that contains a valid RAID config but that RAID cannot be completed and used, how are such disks supposed to show up ? Anyhow the ataraid code was about to change, but then hope started to show again that we could loose ccd/vinum/raidframe/ataraid and get one proper GEOM implementation, that would make life perfect (about RAID at least) so I've put further work on ataraid on the backburner since I dont want duplicate work in there (we have PLENTY of that already).... However since some of our worst armchair generals and whiners are involved in this, I dont expect an outcome soon, if any at all ;) -- -Søren
