@jggimi: That pciide0 warning indicates that the second channel isn't in use.. an IDE controller has 2 channels, a channel can have 2 devices (master/slave).
Code:
wd0 at pciide0 channel 0 drive 0: <ST340015A>
He only has 1 IDE device on the first channel (0..) and it's in the master position (..0).
