I have a 160gb PATA disk and a 20gb PATA disk which is setup as master. I want to buy a SATA disk>200gb, and convert the 20gb disk to an external one. Can i setup the SATA as master? is this wise, like keeping both SATA+PATA hdds in the system? also, i dont have a floppy drive, how do i install the SATA drivers that i had got with my mobo? is there any workaround for this.
