The guide screws mounted on the left side of the drive are standard-head screws. The guide
screws mounted on the right side of the drive are shoulder-head screws. The drive release latch
will not work properly if the wrong screws are installed.
To replace the 3.5-inch drive, reverse the above procedure.
