[QUOTE="Dack, post: 999548, member: 97817"] Just a quick update to let people know why the 1.0a should be better - for future use. The version 1.0 overwrites all of the unused sector data with 0xFF. The 1.0a version only overwrites the data content of the 32k sector. It leaves the SHA bytes intact. The layout of the Wii disc means that the SHA block signatures are all referenced/checked by the signed global hash table. One of the things that Nintendo could do in a firmware update is do a few random sector reads to see if the SHAs match what is expected in the hash table. If not then there is an 'issue' and a potentially dodgy disc. By keeping the sha blocks of the sectors intact this check should now pass [img]http://gbatemp.net/vanilla/emoticons/smile.gif[/img] However..... If a block was marked as unused and then 'scrubbed' it would be possible for the *program on the disc* to check for the actual data content in the sector. The reason this is an issue is that the content of the descrambled block would not then match the expected contents. However 2...... Since it is now possible to extract the application you can then disassemble it to check for direct sector access and, in a future revision of the scrubber software, mark that block as used - preserving the data integrity and so pass the applications check - without having to change the disc applications code. Just some musings..... [/QUOTE]
