I did vinum start vinum0.p1 and everything went as good as expected.

Yesterday I got it once more:

> (da3:sym0:0:3:0): READ(10). CDB: 28 0 4 3c a1 c8 0 0 10 0 
> (da3:sym0:0:3:0): HARDWARE FAILURE info:43ca1c8 asc:40,85

> vinum: vinum0.p1.s0 is stale by force

I'm doing vinum start right now and I'm quite sure it will work ok.
However, I'm a little worried: can my disk be broken?
It's pretty new and still under warranty, so I'd like to change it before anything breaks badly, *if it is*.
Can I possibly blame the controller (it's a Tekram DC-390U2W)? Wouldn't it be strange, since it's always the same HD
(out of 4) that shows this problem?

Any diagnostic tool I can use?

 bye & Thanks
