Prince of Persia T2T problem

Hey guys, i need some help here.

I just downloaded Prince of Persia T2T, installed the game like i should but i can't make it run..

In the NFO it says:

1.Mount in DT4
2.Install Game, use SF KEY:****************
3.Remove all IDE drives and Play.

What exactly are IDE drives and how do i remove them?

Can anybody help me here?

Ok Guys problem solved :D

I just removed the power cable from the DVD-R and the game started right away! :)
