Physical hard drive switch any one see one

im looking for a device that i can plug a sata power connector into and then hook up two hard drives two it and then flipping the switch will let me choose witch hard drive gets power of course i will only do this when the computer is off. i like the idea of being able to run two os's but i dont want to dual boot and want them to be on two seperate hard drives and only the drive powered up im useing it seems like it would be a simple design but i have not seen one for sale

bonus if its fits in a 3.5" slot

if anyone has seen this for sale anywhere give me a heads up

what i done was to cut and put switch in the red wire and then put the switchs in the front cd cover slot

:-O i guess thats a solution kinda hopeing for something that i dont have to hack myself but i will keep that in mind thanks

fits in 5.25' optical drive bay. only plug in HDD with OS you want to boot. Never have to worry about one OS corrupting the other.

I started using this because TimeMachine kept putting trash files on my other OS drives. If I deleted the files, TimeMachine kept asking if I wanted to use the drives for backup.
No way to get rid of TimeMachine to make it stop doing that.
