You will need
  • - Controller IDE SATA;
  • connector USB-SATA.
Turn off the computer, disconnect the system unit from the AC mains. Open the enclosure of the unit. Usually required to remove only the left wall. This will allow you to access to all necessary elements of the PC. If you have two hard drives format SATA, you will need some connectors on the motherboard and special cables. Install both the hard disk in a special compartment and secure them with screws. Make sure that the hard drives are not loose.
Connect both hard drive to the system Board, use SATA cables. To simplify further settings synchronous operation of the drives connect to the SATA1 port of the hard disk on which you will install the operating system.
Connect the power to both the winchesters. To do this, use the cables coming from the power supply of the computer. If the unit has only one SATA cable, then buy a special adapter. It is necessary to connect the IDE cable with a SATA hard drive.
If your motherboard has no SATA ports at all, then buy a special controller that allows you to connect SATA hard drives. With its help, connect hard drives to the motherboard. In this case, you must use the IDE-channels. They represent the wider multi-channel connector.
If you are not able to connect two of the SATA controller to IDE ports, use a USB adapter SATA. In this case, through this controller you need to connect the hard drive which is not installed operating systems. The probability is that this hard disk will be determined only after loading the operating system.
