Are you *very* sure about that? What I thought they told me was that they tested drives until they had enough 238's. If a drive failed as a 238 it was retested as a 225. Therefore a 225 which you buy might be either a drive which failed as RLL or one which was never tested. This would explain why so many pass as RLL in actual service. -- bill davidsen (davidsen@crdos1.crd.GE.COM -or- uunet!crdgw1!crdos1!davidsen) "The world is filled with fools.
