Guys, take a look at "ps3dm_sm set_del_def_encdec_key" command. You
can disable/enable virtual FLASH/internal HDD encryption with that.

And by patching HV process 9 (which sets ATA keys before loading
GameOS) you can disable it permanently. It means you could swap your
internal HDD and use it on another PS3. But you have to restore the
content on it after disabling encryption because all data will be
encrypted of course.

Soon i will implement ENCDEC device driver for PS3 Linux and you will
be able to experiment with ATA encryption. ENCDEC device is
responsible for VFLASH/HDD encryption on PS3.

For more details, see my HV page here:

And thanks to PS3 Linux fans who help me to test my ps3dm-utils Huge
thanks to you guys. I can have fun with PS3 even without having one
actually

And thanks to Dukio for his support with this blog and GIT repository.

總之graf_chokolo釋出關閉硬碟加密的方法了。

關閉硬碟加密後，主機會提示要求重新格式化，因為主機不再有能力辨識加密過
後的資料，所以graf_chokolo建議大家先將主機的資料傳出來備份，然後關掉加
密，重新格式化之後再把之前備份的資料還原。

如果有兩台 PS3主機都透過這個方式關掉硬碟加密，則可以直接對換硬碟而不需
要重新格式化。但對於主機板掛掉要救資料的人而言，這招應該是緩不濟急，因
為在掛掉之前就要先處理過，而且還要祈禱新買的主機也一樣可以用這招把加密
關掉。無論如何，總比SONY跟你兩手一攤說「請節哀」要好得多。
