Changes: - More sane timeouts on ATA commands - Print a security usage if parameters are illegal - Extended the manual page with some examples and notes about which commands are lethal to mounted filesystems - Teach the kernel about the ATA Security command codes (for console printf messages) Even with the kernel changes, a kernel rebuild is not required in order to test the code. http://daniel.roe.ch/code/ata/atasecurity-20081001-complete.diff Please send me feedback. -- Daniel Roethlisberger http://daniel.roe.ch/
