Another way is to either make a 3 device IDE cable or buy one from a place like llama. Then all you would have to do is get a switch set up so that you can turn one hard drive's power on while the other is off. Both the 5v and 12v would be best. So you would need items like;
-3 device IDE cable
-molex Y adapter
-spdt switch (i think)
-hard drive
Again,it's easier to get the Xtender,but I'm just letting you know that there are other ways.
PS-reason you want both the 5v and 12v powers to be switched off when the opther drive is in use....both power and heat. You don't need that power supply heating up the case,as well as the other hard drive.
