Thanks much Scott, I still don't know what you are talking about -- my $3000 to $800 laptops all never needed to swap any drive. But yeah, I got hit on all of them when I was in china, by the china web virus that no U.S. software could do anything [then a china open source thing did the job] So, without the swapping HD concern, what should I do??? z at home still confused ----- Original Message ----- From: "Scott Laird" <sc...@sigkill.org> To: "JZ" <j...@excelsioritsolutions.com> Cc: "Toby Thain" <t...@telegraphics.com.au>; "Brandon High" <bh...@freaks.com>; <zfs-discuss@opensolaris.org>; "Peter Korn" <peter.k...@sun.com>; "Orvar Korvar" <knatte_fnatte_tja...@yahoo.com> Sent: Thursday, January 08, 2009 6:20 PM Subject: Re: [zfs-discuss] ZFS + OpenSolaris for home NAS? > You can't trust any hard drive.
