For SSDs or harddisk which do encryption internally - with or without encryption password in BIOS - an ATA Secure Erase should be enough: http://ata.wiki.kernel.org/index.php/ATA_Secure_Erase Search "site:kernel.org secure erase" on Google and use webcache as long as kernel.org is down. I wiped a Windows 7 installation very quickly from the Intel SSD 320 in my new ThinkPad T520. Had to plug in the SSD externally tough, as the BIOS froze security settings and disabled secure erase for the internel drive. An ATA Secure Erase does not need much write accesses, which is great for SSDs: The drive just forgets the key and then is not able to encrypt the old data anymore. -- Martin 'Helios' Steigerwald - http://www.Lichtvoll.de GPG: 03B0 0D6C 0040 0710 4AFA B82F 991B EAAC A599 84C7 -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
