To remove a hard-disk drive, follow these steps:
When you replace the hard-disk drive bracket, insert the hooks in the slots on
the front of the chassis and slide the bracket to the right. Then lower the
bracket to the bottom of the chassis, making sure that the latch on the drive
bay is engaged (see Figure 4-12). Replace the screw holding the drive bracket
to the drive bay.
NOTE: If you are replacing more than one hard-disk drive in the bracket, do not
fully tighten any of the screws that hold the drives in the bracket until all of the
drives have been placed into the bracket. This prevents the bracket from com-
pressing, which could make it difficult to insert additional drives.
