Hotswapping (Xbox)

From Wiki-Scene

Hotswapping is the "art" of activating a hard drive while it is attached to a console, then connecting it to another device in order to circumvent the lock. Although it can lead to hardware failure it is commonly used to modify or repair systems.

If at all possible, it is recommended to extract the console's EEPROM data to unlock the drive completely instead of hotswapping. In some cases a master passcode can be used to unlock the drive instead (but not to relock it).

When an Xbox starts up and finds a lock on the hard drive installed, it will attempt to access it using a code based on the drive's serial number and a key stored in the EEPROM. Assuming this is succesful the drive will then grant access until the next time it is powered up.

Hotswapping works by having the Xbox provide the code to the drive, then unplugging the IDE cable and re-attaching the drive to another device (such as a PC). So long as the drive is not powered down during the process it will continue to give access to the new system it is connected to.

It is recommended to ground the Xbox console to whatever system the hard drive is to be transferred to. This is so that the difference in charges between the two devices does not cause a surge (which would increase the chances of damaged equipment). Also note that most hard drives are not designed to be seriously bumped while operating, it is good practise to at least loosen the IDE cable before beginning in order to minimise the shock of the disconnection.

There's a lot of different recommendations concerning the best time to unplug the drive from the console, and the best time to attach it to the new system. I'll leave it to someone with more experience in the matter to fill in the details.

Once the drive has been hotswapped, the FATX file system it holds can then be accessed using software such as XBoxHDM or Xplorer360.
