Sorry for my english and for my noob-questions:
1 The samsung fw is not crypted?
2 The hitachi fw is crypted, but is it crypted on flash or is it being crypted while transferred through ATAPI (if i dump directly the flash with a programmer i'll get the unencrypted fw?)
3 Is the key in the same location for same drive manufacturer or not? Is it always 16bytes ?
links to posts or info are appreciated....
1. Correct the samsung is not scrambled
2. Hitachi is scrambled on the flash, Using seventhson's memdump it is saved unscrambled, but flashsec needs it to be scrambled before flashing. Scramble the firmware with FirmCrypt by loser. If you dump directly with a programmer you get the scrambled firmware. Use FirmCrypt to scramble/descramble. If you are flashing with flashsec there are 3 versions, for a 46, 47 and 59. You cannot use flashsec to change firmware versions, a programmer is currently needed.
3. Key is in the same position for Hitachi, varies slightly for Samsungs, always 16 bytes.
