Some Seagate drives seem to have an issue on the 128GB boundary - look
around line 230ish of your sys/dev/ata/wd.c.  NetBSD 3.0.2 should have
an extry for ST3160812A* though which should catch your drive...

I've been using a pair of ST3320620As in a mirror here with no problems
on the netbsd-3 branch since last July.
