Installing a Hard Drive
1 Check the documentation for the drive to verify that it is configured for your computer.
NOTICE:
To avoid damage to the drive, do not set it on a hard surface. Instead, set the drive on a surface, such as
a foam pad, that will sufficiently cushion it.
2 Unpack the replacement hard drive, and prepare it for installation.
