5.When mounting an additional HDD, the primary master has to be mounted.
In general, HDD should be installed as the primary master of IDE, and the CD-RW drive should be installed as the secondary master of IDE.
Mount the HDD you want to add after setting the master/slave jumpers in the proper order.
When adding one - Primary slave (mount on the top of the bracket that has a built-in HDD when coming out of factory.)
When adding two - Secondary Slave (mount to the upper bracket of the built-in CD-RW.)
Mount the HDD to the bracket-HDD with (A)SCREW-SPECIAL (BWH,6-32UNC,L10.5) and (B)SCREW-TAPTITE (BH,+,S,M3,L6,ZPC) (4 spots) that was provided as an accessory. (The screws have to be tightened so that it doesn't vibrate loose.)
❉(B)SCREW-MACHINE is provided when purchasing the HDD.
6.Re-mount built-in HDD bracket-HDD to the place where it was separated from. Place the bracket-HDD (A) so that all the five mounting spots on the bottom and the bracket-HDD's mounting holes are perfectly aligned, then slide it toward the outside of the product and tighten the screws.
For the bracket-HDD (B), place it so that all the four mounting spots on the bottom and the bracket-HDD's mounting holes are perfectly aligned, then tighten the screws.)
