4.x has a new IDE driver, which doesn't have any documented problems
with large drives.

Is this the error you're implying?  It would be nice to know whether
you had any problems with newfs or mount.  Are there any files on it?
What other history?  How does your treatment of this partition compare
to that of partitions f or g?

There's nothing particularly surprising about the disk label.  It
might be yet another "big drive" problem with the wd driver.  I'd hope
that the ad driver would do better.
