Removing the Hard Drive
When replacing this drive, transfer the four screws that take the place of drive rails from the old
drive to the new one. There are two screws on each side of the drive.
The guide screws mounted in the front two holes are standard-head screws. The
guide screws mounted in the rear two holes are shoulder-head screws. The drive
release latch will not work properly if the wrong screws are installed in the rear
two holes.
To replace the drive, reverse the removal procedures.

internal components of the drive.
