4 CONFIGURATION

4.1 CONFIGURATION PREREQUISITES

4.1.1 SATA HOST CONNECTIONS

This guide assumes that you have already attached the TowerRAID TR4UT/TR4UT-B to a host computer that has

been installed with the R622 HBA (Host Bridge Adapter) or another SATA HBA with Port Multiplier (PM) support.

If you use a host controller that does not provide Port Multiplier support (Such as Intel ICH):

• The CLEAN MODE storage policy is unavailable when configuring the TEAR BOX SATA RAID III. Only one disk is

available on the host computer.

• Virtual volumes that you create in the Advanced Configuration Wizard must use at least 8 gigabytes (GB) of

available system capacity.

4.1.2 USB HOST CONNECTIONS

If you are connecting your TowerRAID TR4UT/TR4UT-B using a USB connection to your host, the USB port should

be compliant with USB 1.0, 2.0 or connected to a USB hub.

4.2 CHANGING HOST CONNECTIONS

The TowerRAID TR4UT/TR4UT-B supports both USB and eSATA host connections, although only one connection can be

attached at any given time. For the best data transfer performance, you should always use the eSATA host connection.

If it becomes necessary to change the host connection between eSATA and USB, the host computer system and the

TowerRAID TR4UT/TR4UT-B should both be powered down prior to making the host connection change to avoid any

potential data loss or corruption. After changing the host connection, all items can be powered-up to resume operation

with the new host connection.

4.3 DISCONNECTING A USB DEVICE

USB 2.0 external devices provide support for “plug & play” connection, so that your USB storage device can be connected

and disconnected while the computer is running. To prevent data loss or other failures, you must follow these steps when

disconnecting your USB 2.0 storage device from your host computer system. Once the physical USB device is disconnected,

any volumes that are associated with that device will become unavailable. On O/S (Opration Systems), the TowerRAID

TR4UT/TR4UT-B must be stopped from O/S before any devices can be disconnected.

4.3.1 WINDOWS SYSTEMS

1. Click on the Eject icon (a small green arrow over a hardware image) in the System Tray located in the lower

right-hand side of your screen.

2. A message will appear listing all of the devices that the Eject icon controls. Click on the “Safely remove USB

Mass Storage Device” item.
