The fix for this was pulled up to netbsd-4-0 on march, 30:
revision 1.335.2.1.4.1
date: 2008/03/30 14:44:42;  author: jdc;  state: Exp;  lines: +3 -3
Pull up revision 1.359 (requested by bouyer in ticket #1094).

The Hitachi HDP725025GLA380 returns "aborted command" instead of
"id not found" when hitting the LBA48 bug, so also install the
LBA48 bug workaround on "aborted command" errors.
