Configuration rules and assumptions when installing both
SATA and PATA optical disk drives in the same
workstation
This section provides information on the sequence in which the workstation detects and assigns ODD
IDs and drive letters when both SATA and PATA ODDs are installed on a workstation. It also provides
configuration rules that determine which SATA ports are functional and which ports can be used to
update system BIOS.

Drive detection and assignment sequence

When mixing PATA and SATA ODDs in a workstation, the PATA optical drive will always be detected
first by the system. For example, if the first ODD is a SATA drive and second ODD a PATA drive, the
system will detect the PATA ODD drive first. This will generally result in the PATA ODD being assigned
the lower drive ID or drive designation letter by the operating system.

Workstation SATA port configuration rules

Port configuration rules are determined individually by workstation product as shown in the following
subsection.
xw9400 Workstation BIOS configuration
When the xw9400 Workstation is set to RAID Mode in BIOS, any SATA ports that have an ODD
connected to them must have RAID turned off.
xw8400 Workstation, xw6400 Workstation, xw4400 Workstation, xw6600 Workstation,
and xw8600 Workstation SATA configuration mode settings
When the SATA Configuration Mode for these workstations is set to:
●
Separate Mode - Only SATA ports 0, 1, 2, and 3 are functional for any SATA devices.
●
Combined Mode - Only SATA ports 0 and 2 are functional for any SATA devices.
●
RAID/AHCI Mode - You will not be able to update system BIOS from the SATA ODD.
●
Combined Mode or Separate Mode - BIOS can be updated using a SATA ODD attached to
functional ports.
NOTE: The xw4550 Workstation and xw4600 Workstation do not support PATA optical disk drives.

Preparing for installation

Before beginning installation of the SATA ODD, ensure that the installation kit contains all necessary
items, that you have the required tools, that you understand the necessary precautions, and that you
have prepared the workstation, as described in the following subsections.

Tools required

You may need the following to install the optical drive:
●
Torx T-15 screwdriver or flat-bladed screwdriver
