Locking New Hd - Password

The eeprom is used to generate the HDD password.  Locking a hard drive isn't an xbox/microsoft thing, it's an encryption feature present on certain drives -- mostly used by corporate/foil-hat types.  MS just happens to require the HDD be locked as part of their anti-hacking measures.  Think of your eeprom.bin as the encryption key... as long as you have it, and as long as you use the same tool to lock/unlock it, you're safe.

Hi,

the xbox calculates the HDD unlocking password from the eeprom hddkey and the harddisk model and serial number.

the eeprom hddkey differs for every xbox.
the harddisk model and serial number differs for every harddisk.

So, another harddisk will need to be locked with another password.

I think you also confuse the tsop flash with the eeprom. The Tsop flash is the chip containting the xbox bios. You need to solder a couple of jumpers if you want to reflash that. It was 1 megabyte in size on 1.0 and 1.1 xboxes. On 1.6 xboxes, it can't be rewritten. The eeprom is a small 256 byte memory chip that contains the information that differs for every xbox like the serial number and hddkey. You can reprogram that chip without any hardware modification to the motherboard.

regards.
