>Description:
	There LBA48 required by some of Seagate drives. Unfortunately Latest
500G SATA drive (ST3500841NS) also require this hack. There are hack to
use pmatch(9) applied v1.310 of wd.c but it can't catch this newer drive
since pattern does not match.

>How-To-Repeat:
	Use ST3500841NS, then run following:
	dd if=/dev/zero of=/dev/rwd1d seek=268435000 count=1000
	You'll get I/O error.

>Fix:
	Following fix works. Of course it is possible to merge it to other
	patterns.
