Even though the actual T13 standard must be purchased, you can find the documents and drafts of it online at various places by googling for appropriate keywords. For example: http://hddguru.com/content/en/documentation/2006.01.27-ATA-ATAPI-7/ The ATA command set, including the ATA Security commands, is in vol. 1. In 2005, there was a much-cited article in the German c't magazine about the security implications of ATA Security, which might be worth a read too. It is available online in English: http://www.heise.de/ct/english/05/08/172/ -- Daniel Roethlisberger http://daniel.roe.ch/
