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 successful 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's shielding 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.
Just because the console is on does not mean the lock is open. There are various methods to remove the IDE cable at the correct moment:
- While running the MS Dash, play a soundtrack, pause the music and remove the cable.
- If the MS Dash cannot be accessed, remove the DVD drive prior to starting the console. When it turns on it'll boot to an error 12. Remove the cable AS SOON AS the LED on the front of the console first turns red.
Attach the cable to your computer as it starts it's own boot up sequence. If the computer does not detect the drive in this manner, try disabling the drive detection feature in your CMOS settings.
Once the drive has been successfully hotswapped, the FATX file system it holds can then be accessed using software such as XBoxHDM or Xplorer360.
Note that every attempt, failed or otherwise, brings you a step closer to irreparably damaging your drive. If in doubt, obtain your EEPROM data using a reader and unlock the drive safely. If you already have your EEPROM backed up, you should of course not even be considering a hotswap.
