Ok, you've hit the 28bit limit of the ATA specification.
The ATA spec has been extended to allow 48bit addresses, and the netbsd
kernel will use the extended commands (at least in current).

I think the 48bit LBA support also went into 1.6.

That message just means you have a blank drive (no 0xaa55 at the end of
sector 0).  However it also comes from the 1.6 fdisk, the one in 'current'
has a slightly different text.

Which version of NetBSDis this?

The output from the wd driver was chanegd to 'LBA addressing' in Dec 2000.
I think this was after the 1.5 freeze - so maybe you are running 1.5.?

You'll need to upgrade to 1.6.something
