Installing a 3.5-inch Drive into a Drive Bay
The 3.5-inch bay is located underneath the 5.25-inch drive. To install a drive into the 3.5-inch bay:
NOTE:
Install guide screws to ensure the drive will line up correctly in the drive cage and lock in
place. HP has provided extra guide screws for the drive bays (four 6-32 standard screws and four M3
metric screws), installed in the front of the chassis, under the front bezel. A secondary hard drive
uses 6-32 standard screws. All other drives (except the primary hard drive) use M3 metric screws.
The HP-supplied M3 metric screws are black and the HP-supplied 6-32 standard screws are silver.
Refer to 
 for illustrations of the guide screw locations.
