MAC Hard Drive Installing Initializing Partitioning loading OS

Before you being make sure all date is backed up on a separate drive.

Instructions are for a MAC Pro Desktop, but may apply to other models.

  1. Unscrew the screw on the back of the MAC.
  2. Pop the side open by pushing the side panel BACK. (Stand in front of the MAC and push the right side toward the back of the computer.  Sometimes it is tough to push back so keep trying.
  3. Push the long button-like rectangle on the back of the computer.  This will release the front of the hard drive bays so you can pull out one of the brackets.
  4. Select a bay that does not have a hard drive and pull outward.
  5. Lay the hard drive you are going to put into the computer so you can see all the circuits facing upward and the metal connections pointed away from you.
  6. Lay the bracket panel down next to the drive so the open end (where the two posts are) is pointed forward away from you.
  7. Turn the hard drive over and place it on the bracket.  The bracket for the MAC PRO already has screws that are mounted into the bracket.  So, you just need to match up the screws and the holes on the hard drive and screw them in using a Philips head screwdriver (it won’t look like you need a Philips head, but you do).
  8. Seat the hard drive bracket back into the MAC PRO and gently push in.

That’s it.  Your hardware installation is complete.  Now you’ll need to initialize.

INITIALIZING THE HARD DRIVE

  1. Restart your computer.
  2. A message saying your computer cannot recognize the hard drive will pop up.  It already has a button that offers to initialize.  Press the button.  If you do not see the initialize message, then restart your computer again.  Make sure your hard drive is seated snugly into the drive bay of your computer.
  3. After you click initialize it will bring up the disk utilities.  You should see your hard drive in the list.  If you do see the hard drive, then you have successfully initialized.NOTE:  If the initialize option does not pop up and your computer does not see the hard drive, try switching to another bay, if possible.

Now you need to Format or Partition your drive.
