When a 3.5 inch mounting buy is available, mounting brackets are not required. If a 5.25 inch mounting bay is used, mounting brackets will be required to mount the hard drive in the system case. After the hard drive is prepared with mounting brackets if required and the jumpers are set correctly, the drive can be mounted in a device bay and secured. Be sure to secure the drive with all four screws in the device bay. This provides grounding and protection from stock and vibration.
Computer systems use different methods for mounting hard drives.
Refer to the computer user's manual or you can contact the manufacturer for specific mounting instructions. In order for the computer to recognize that the hard drive is in the system, the power cable and the IDE interface cable must be properly connected. On the back of the hard drive you will see two connector and the jumper block. The power connector has three colored wires black, red, yellow. There is only one way to plug in the power connector.
