C.2 Information wiping methods used by Seagate BlackArmor Backup The table below briefly describes information wiping methods used by Seagate. Each description features the number of hard disk sector passes along with the number(s) written to each sector byte. The description of built-in information wiping methods No. Algorithm (writing Passes Record method) 1. United States 4 1st pass - randomly selected symbols to Department of Defense 5220.22- each byte of each sector, 2 - complementary to written during the 1st M pass; 3 - random symbols again; 4 - writing verification. 2. United States: 4 1st pass - 0x01 to all sectors, 2 - NAVSO P-5239-26 0x27FFFFFF, 3 - random symbol (RLL) sequences, 4 - verification. 3. United States: 4 1st pass - 0x01 to all sectors, 2 - NAVSO P-5239-26 0x7FFFFFFF, 3 - random symbol (MFM) sequences, 4 - verification. 4. German: VSITR 7 1st - 6th - alternate sequences of: 0x00 and 0xFF; 7th - 0xAA; i.e. 0x00, 0xFF, 0x00, 0xFF, 0x00, 0xFF, 0xAA. 5. Russian: GOST 1 P50739-95 Logical zeros (0x00 numbers) to each byte of each sector for 6th to 4th security level systems. 6. Peter Gutmann's 35 method 7. Bruce Schneier's 7 method 8. Fast 1 Randomly selected symbols (numbers) to each byte of each sector for 3rd to 1st security level systems. Peter Gutmann's method is very sophisticated. It's based on his theory of hard disk information wiping (see http://www.cs.auckland.ac.nz/~pgut001 /pubs/secure_del.html). Bruce Schneier offers a seven-pass overwriting method in his Applied Cryptography book. 1st pass - 0xFF, 2nd pass - 0x00, and then five times with a cryptographically secure pseudo-random sequence. Logical zeros (0x00 numbers) to all sectors to wipe. 126 Copyright (c) 2000-2009 Acronis. All rights reserved. Copyright (c) 2009 Seagate Technology LLC. All Rights Reserved.
