Or is it a bug? The HPA is a feature of the drive, not the OS or software, so dd has no idea whether or not there is one and can not "get around" it. To unlock the full capacity of the drive you have to send commands to the drive. You can have the libata driver do this by setting libata.ignore_hpa=1. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBAgAGBQJSXvYTAAoJEJrBOlT6nu75nbIH/3fbuqzWpJWKFr9ngYvHcMcB FkMNDF7Up0JrmaT/7/uXwfGVjUYiGiPdGI9EzmizpKhunfdxc5qkmiM8bD1M2+NW Nk8dJp/Pc2gw4N++w7IsqQ4U5vPPlqLYRDmYGecC7HOSpRLecHRKXd8V3vMJYvDd /Tw463Jk/svlZOBGUmtQZnlZnIsjRgcxWqDfMx+4yskjDTVYy7dPjxEa8OEqkBmB X75N2RN+k7KS/CHtXLMdZ/RwqovSvpbQPuc8WoTgq35GA+IDhFNT/iLExgSooLp+ ijE4JmWsUg867ZxVgYFqKzjARBxYwxxt2sTBk9tFG9AxbZEGldvSGW7PeRgwIjw= =d4XP -----END PGP SIGNATURE----- From debbugs-submit-bounces@debbugs.gnu.org Wed Oct 16 16:31:00 2013 Received: (at 15633) by debbugs.gnu.org; 16 Oct 2013 20:31:01 +0000 Received: from localhost ([127.0.0.1]:54659 helo=debbugs.gnu.org) by debbugs.gnu.org with esmtp (Exim 4.80) (envelope-from ) id 1VWXkC-0005HU-Fc for submit@debbugs.gnu.org; Wed, 16 Oct 2013 16:31:00 -0400 Received: from mail1.vodafone.ie ([213.233.128.43]:27700) by debbugs.gnu.org with esmtp (Exim 4.80) (envelope-from ) id 1VWXk9-0005HF-3q for 15633@debbugs.gnu.org; Wed, 16 Oct 2013 16:30:57 -0400 X-IronPort-Anti-Spam-Filtered: true X-IronPort-Anti-Spam-Result: ApMBAEr3XlJtTbsX/2dsb2JhbAANTb8LgnqBNYMZAQEBAwEyAUsLCw0LCRYPCQMCAQIBRRMIAQGHfKwhkz6PWBaEDwOeY45I Received: from unknown (HELO [192.168.1.79]) ([109.77.187.23]) by mail1.vodafone.ie with ESMTP; 16 Oct 2013 21:30:49 +0100 Message-ID: <525EF74A.1080908@draigBrady.com> Date: Wed, 16 Oct 2013 21:30:02 +0100 From: =?ISO-8859-1?Q?P=E1draig_Brady?= User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:17.0) Gecko/20130110 Thunderbird/17.0.2 MIME-Version: 1.0 To: 15633@debbugs.gnu.org Subject: Re: bug#15633: dd and host protected area References: In-Reply-To: X-Enigmail-Version: 1.5.2 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 8bit X-Spam-Score: 0.0 (/) X-Debbugs-Envelope-To: 15633 X-BeenThere: debbugs-submit@debbugs.gnu.org X-Mailman-Version: 2.1.15 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: debbugs-submit-bounces@debbugs.gnu.org Sender: "Debbugs-submit" X-Spam-Score: 0.0 (/) tag 15633 notabug close 15633 stop On 10/16/2013 08:19 AM, Peter D. wrote: > Hi, > > Is it deliberate that dd can not read from, or write to the host protected > area?
