About USB 2.0 Performance

Your Adaptec ACS-120 USB Enclosure is a USB 2.0 device. For it to
operate at USB 2.0 speeds, it must be connected to a USB 2.0 port,
and USB 2.0 drivers must be installed on your computer.

If your computer does not have a built-in USB 2.0 port, Adaptec
recommends connecting the ACS-120 USB Enclosure to an Adaptec
USB 2.0 adapter for the highest-quality USB 2.0 connection.

Getting Started Checklist

Complete these steps to install and begin using your Adaptec
ACS-120 USB Enclosure:

❏ Prepare the disk drive for installation (see below).
❏ Install the disk drive (see page 7).
❏ Install the device driver on your computer—Windows 98SE only

(see page 8).

❏ Connect the enclosure (see page 9).
❏ Prepare the disk drive for use (see page 1 1).

6

Preparing the Disk Drive for Installation

Before installing the disk drive, ensure that it meets the
requirements listed in Supported Disk Drives on page 5.

Set the drive jumper to Master or Device 0 mode (or equivalent, as
described on your disk drive), following the instructions on your
disk drive.

Installing a Disk Drive

Note: You need a Phillips screwdriver to complete this task.

To install a disk drive into your USB Enclosure:
1 Use a screwdriver to remove the enclosure cover, as shown

below.

2 Connect the EIDE/IDE connector of your disk drive to the

interface connector inside the enclosure cover.

3 Slide the disk drive into the enclosure, then use the screws you

removed in St ep 1 on page 7 to secure the enclosure cover, as
shown below.

Installing the Device Driver–Windows 98SE Only

Note: Windows XP/2000/Me and Macintosh users—No driver

installation is required. Your Adaptec ACS-120 USB Enclosure
works with the drivers built into your operating system.

Befo re you begin, ensure you have the m ost recent operating
system updates installed on your computer. Refer to the Microsoft
Web site at

www.microsoft.com to download updates.

To install the device driver:

1 Power on your computer, if you have not already done so.
2 Insert the CD into your CD-ROM drive.
3 From the Windows Start menu, click Run, then click Browse.
4 Browse to the CD-ROM drive, then double-click Setup.exe to

begin the driver installation.

5 Follow the on-screen instructions to install the driver.

8

Connecting and Powering On

Note: Windows 98SE users only—You must install the device

drivers before connecting and powering on the enclosure.

Plug the mini-connector of the included USB Y-cable (shown on

page 5) into the USB port on the enclosure, then plug the main

connector into an available USB 2.0 port on your computer.
When your computer is powered on, the enclosure is also power ed

on. See Getting Enough Power on page 9 for more information.
You have successfully installed and connected your Adaptec

ACS-120 enclosure.

Getting Enough Po wer

The Adaptec ACS-120 USB Enclosure is bus-powered. However, if
you connect the enclosure to an adapter (such as a CardBus) that is
not able to supply adequate power, you may see one of these
messages:

USB Powe r Sur ge (Windows XP)
The hub doesn’t have enough power available... (Windows 2000)
USB power exceeded (Windows Me and Windows 98SE)

If one of these messages appears, provide more power to the
enclosure:

■ First, try connecting the secondary connector on the Y-cable to

your computer. For instructions, see page 10.

■ If the problem persists, connect an external power supply (not

included) to the enclosure. For instructions, see page 10.

9

Connecting the USB Y-Cable to a Second USB 2.0 Port

If you have another available USB port on your computer (does not
have to be a USB 2.0 port), plug in the Y-cable’s secondary
connector. The secondary USB connector provides additional
power to the enclosure.

Plug main connector into USB 2.0
port for data and power connection

Plug secondary connector

into any other USB port

for additional power

Plug into the enclosure

Connecting an External Power Supply

If the USB Y-cable does not supply enough power, try connecting
an external power supply (not included) to the power port on the
enclosure.

The external power supply must meet these requirements:

■ Rated at 5 Volts

■ Capable of 1–1.5 Amps (depending on disk drive power

consumption)

■ Connector size:

■ 3.5 mm outside (-) diameter

■ 1.35 mm inside (+) diameter

■ 10 mm length

Next Steps

!

If you have installed a new disk drive in your enclosure, you must
prepare it for use by initializing and formatting it, so that your
computer can recognize and communicate with it.

Caution: If you’ve used the disk drive previously and want to
preserve the data on it, do not initialize and format the disk
drive or you’ll erase all the data on it. Refer to your operating
system documentation for more information.

The process of initializing and formatting a new disk drive differs
by operating system. Refer to your operating system
documentation for instructions on completing these tasks.

Note: For technical assistance with the initialization and
formatting process, please contact Microsoft (Windows users)
or Apple (Macintosh users).

Troubleshooting

If you have problems installing or using your Adaptec ACS-120
USB Enclosure, work through this list of suggestions:

■ Ensure that the disk drive has been properly installed.

■ Try connecting the enclosure to your computer through a

different USB port.

■ Try connecting the enclosure to your computer using a different

USB cable.

■ Try plugging the USB Y- cable’s secondar y connector (shown on

page 5) into any USB port on your computer, as described on
page 10. (Yo u may want to do this even if the LED indicator on

the enclosure is green and even though you may not receive an
error message from the operating system.)

If the problem persists, try connecting an external power
supply, as described on page 10.

■ If you are using Windows with a file system other than NTFS,

and the file system of the disk drive installed in the Adaptec
ACS-120 is NTSF, Windows may not recognize or be able to
read from or write to the disk drive.

See the Table below for compatibility information:

Operating System
File System

FAT16 FAT16 OK

FAT 32 FAT16 or FAT32 OK

NTFS FAT16 or FAT32 or NTFS Yes
