Drives that are installed in internal bays are called internal drives. A hard disk drive (HDD) is an example of an internal drive.

To install the HDD, follow these steps:

Step 1. Position the HDD so that it aligns with the 3.5 inch (8.9 cm.) drive bay opening.

Step 2. Insert the HDD into the drive bay so that the screw holes in the drive line up with the screw holes in the case.

Step 3. Secure the HDD to the case using the proper screws.
