size of connector you may do well to apply some Araldite or equivalent to hold it in place, or
modify the removed port block to re-use the black plastic bridge. Be careful when chopping

Using a PC DVD drive
Remove the power cable from the Xbox drive and attach a power cable splitter (can get from
most pc stores) and plug both drives in. Sit your PC drive on top of the Xbox drive. Then
remove the IDE cable from the Xbox drive and insert it into the PC drive.
You can't actually replace the drive as the Xbox still needs to access it via the yellow cable.
Also if you want to play originals you'll have to plug the Xbox drive back in.
There are then 2 methods to boot - put a disc in the pc drive and reset or if that doesn't work
put an original in the xbox drive and your backup in the pc drive.
