The old XBox didn't encrypt the data on the hard drive - instead, it used a password on the drive firmware that almost all modern hard drives support (your home pc's drive almost certainly supports the same thing, even if your bios doesn't) Defeating the password requires one of: a) obtaining the password b) replacing the drive bios or controller c) using an already unlocked drive d) defeating the os on a running system to allow writes to the drive
all known xbox hacks used method c) or d) - using a game to bypass the write protection, or disconnecting the ide cable after the drive was unlocked and using a standard usb>>ide adaptor to write to the drive. --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
