I am not in front of the machine, but let me tell you that mdstat shows
a full 480GB RAID5. There are no partitions (hde/g/i/k are used raw).

Again, I think udma133 and 48bit addressing are two, independent issues.
The first is an electronic spec for the hardware, the second is an api
standard which, it seems, can run at any speed.

Maybe Andre can make a clear statement here?
