The Mac Pro (Early 2008) computer can accommodate four hard drives in its four internal hard drive bays. In most configurations, a single SATA hard drive occupies the far left bay (bay 1). You can install additional SATA drives in the second, third, and fourth hard drive bays. Or you can install up to four SAS drives.


No parts required.

  1. Shut down the computer.
    • Shut down the computer.

    • Warning: Always shut down the computer before opening it to avoid damaging its internal components or the components you are installing. Do not open the computer or attempt to install items inside it while it is on.

    • Wait 5 to 10 minutes to allow the computer’s internal components to cool.

    • Warning: After you shut down the system, the internal components can be very hot. You must let the computer cool down before continuing.

    • Unplug all external cables from the computer except the power cord.

    • Touch the metal PCI access covers on the back of the computer to discharge any static electricity from your body.

    • Important: Hold the drive by its sides. Be careful not to touch the printed circuit board on the bottom of the drive.

    • Replacement Note: Slide the carrier and drive over the guides and into the drive bay, until you feel the drive snap into place.

Success - I just wanted to remove the hard drive because my poor old Mac Pro has more problems than I can deal with. I wish the solution were as simple as replacing the hard drive, but at least I have that to reuse if I wish.
