For optimal performance, connect hard drives to the primary
controller. Connect expansion devices, such as ATA optical
drives, tape drives, and diskette drives, to the secondary
controller.
■
Install either a third-height or a half-height drive into a
half-height bay.
■
Install guide screws to ensure that the drive lines up correctly in
the drive cage. Compaq has provided extra guide screws installed
in the front of the computer chassis behind the front bezel. Some
options use M3 metric hardware. Compaq-supplied metric screws
are black. Compaq-supplied standard screws are silver.
■
If only one device is connected to a cable, that device must be
attached to the end (Device 0) connector.
If you have only one device, make sure to connect it to the Device 0
connector. If you connect it to the Device 1 connector, the system will
not recognize the device and you may get a "no fixed disk found"
error message.
