clicks to secure it.

2.2 Rack Mounting Warnings

• Elevated Operating Ambient: If installed in a closed or multi-

unit rack assembly, the operating ambient temperature of the

rack environment may be greater than room ambient.

• Reduced Air Flow: Installation of the equipment in a rack

should be such that the amount of air ﬂow required for safe

operation of the equipment is not compromised.

• Mechanical Loading: Mounting of the equipment in the rack

should be such that a hazardous condition is not achieved due to

uneven mechanical loading.

• Circuit Overloading: Consideration should be given to the

connection of the equipment to the supply circuit and the effect

that overloading the circuits might have on over current protec-

tion and supply wiring. Appropriate consideration of equipment

nameplate ratings should be used when addressing this concern.

• Reliable Earthing: Reliable earthing of rack-mounted equip-

ment should be maintained. Particular attention should be given

to supply connections other than direct connections to the

branch circuit (e.g. use of power strips).

3. Operating RAX215DC-XJ

Connect the SFF-8088 data cable to the RAX and your host computer. Plug

in the power cord. Turn on the power. Insert the carriers into the frame

and the “Auto Start” feature will power up the drives automatically.

Your RAX is now ready to use! If the hard drives are already formatted,

the RAX can be used right away. If the hard drives are brand new, or the

formats are not compatible with your computer, the drives will need to

be formatted before being used. See the following section, “Usage with

Mac and Windows Operating Systems.”

NOTE: A ﬂashing red LED on the bay indicates bay fan failure.

Call CRU technical support for assistance.

4. Usage with Mac and Windows Operating Systems

4.1 Usage with Mac OS X

4.1.1 Compatibility

RAX uses 3.5-inch SATA (Serial-ATA) hard drives only. RAX does

not require drivers for operation under Mac OS X. However, if you

install a host card speciﬁcally to work with this product, that card

may require drivers. See your card’s User Manual for drivers and

instructions.

4.1.2 Formatting a Drive

If you purchased your RAX pre-populated with hard drives, this

step should not be necessary unless you wish to change the format

or erase the drive. To format, use Mac OS X’s Disk Utility (found in

the applications folder).

a. Click on the drive in the window to the left (see picture below).

b. Click the Erase tab in the window to the right (see picture

below).

c. Select the format type. Most users prefer Mac OS Extended

with Journaling (HFS+), which is required for compatibility

with Time Machine (OS 10.5 or newer). If you need to use your

RAX with both Mac and Windows computers, select MS-DOS

File System instead.

d. Enter a name for the new volume and then click “Erase” to

start the process.

4.1.3 Mounting and Unmounting Volumes

If the hard drives installed in RAX are

already formatted, an icon representing

the drive’s volume will appear (mount)

on the desktop. You can begin using

the volume right away. If the drive is

unformatted, a message will appear

on the desktop saying that the disk is

unreadable. You can use OS X’s Disk

Utility to easily format the drive (see

section above).

Page 2

RTX220 QR - Manual

Unmount the volume before powering down the unit by dragging

the volume’s icon to the trash bin, or by selecting the volume

then pressing Command-E. Disconnecting the unit without ﬁrst

unmounting the volume can result in data loss.

4.1.4 Creating a Boot Drive

To activate this feature, you must ﬁrst install OS X on the hard

drive in your carrier. The easiest way to do this is to clone an

existing system drive using a utility such as Carbon Copy Cloner or

Super Duper. Next, go to System Preferences --> Startup Disk. A

window will list the available bootable volumes. Select the volume

from which you wish to boot. Another method is to hold down the

Option key during boot up. A screen should appear that allows you

to select the volume you wish to use. This is useful if you wish to

boot from your RAX hard drive only some of the time.

4.2 Usage with Windows Operating Systems

4.2.1 Compatibility

RAX uses 3.5-inch SATA (Serial-ATA) hard drives only. RAX does

not require drivers for operation under Windows XP, Vista, or

7. However, if you install a host card speciﬁcally to work with

this product, that card may require drivers. See your card’s User

Manual for drivers and instructions.

4.2.2 Formatting a Drive

If you purchased your RAX pre-populated with a hard drive, this

step should not be necessary unless you wish to change the format

or erase the drive. To format, use the Disk Management utility.

a. Right-click on My Computer, then select Manage. The Com-

puter Management window will open.

b. In the left pane of this window, left-click on Disk Management.

c. The drive should appear in the list of Disks in the lower

middle/right pane (see picture below).

NOTE: Windows XP does not support GPT or volumes larger than 2TB.

You may need to scroll down to see it. If the drive is already

formatted, you can identify it easily by its volume name. If it’s

unformatted, the Drive Properties Box will say “Unallocated” and

you’ll need to initialize the disk before formatting it. Initialize

the disk by right-clicking the Device Properties Box and selecting

Initialize Disk.

d. To format the drive, right-click the Drive Properties Box and

select Format.

e. If you are prompted to select a partition type, select MBR for

volumes 2TB or smaller, or GPT for volumes larger than 2TB.

f. Click through several more windows, leaving the default set-

tings, until you see a window that allows selection of a ﬁle

system. Choose NTFS and enter a name for the new volume.

Be sure to check the box labeled “Perform a quick format”

unless you want to completely erase any data on the drive

and have time to wait. A quick format should take less than a

minute, while standard formatting may take several hours.

g. Click “Next” and then “Finish” to start the format process.

When the format is complete, the Drive Properties Box will

update to show the new volume name. The new volume can

now be found in My Computer.

4.2.3 Mounting and Ejecting Volumes

If the hard drives attached to RAX are

already formatted, you can begin using

the volume right away. When the unit

is properly connected and turned on, a window may open to allow

you access to the volume. If no window appears, you can ﬁnd the

volume by double-clicking “My Computer.”

Eject the RAX before powering it down by

single-clicking the green arrow icon on the

task bar, then selecting “Safely remove….”

Windows will indicate when it is safe to disconnect RAX. Discon-

necting the unit without ﬁrst ejecting it can result in data loss.

4.2.4 Creating a Boot Drive

Some PC motherboards support booting from an external device. To

activate this feature, you will need to adjust the motherboard’s BIOS

settings. Check with your motherboard’s manufacturer or owner’s

manual for details.

5. Frequently Asked Questions (FAQ)

Q: Why won’t the computer let me eject or unmount my drive?

A: There may be a software application running in the background

with an active link to the drive.

Sometimes, you may see a message such as “The disk is in use and

could not be ejected. Try quitting applications and try again.” Try

invoking the Force Quit feature in OS X to see what software may be

running. For Windows, the equivalent command is CTRL-ALT-DEL.

Drives connected to the computer via eSATA cannot be ejected in

Windows the way FireWire or USB drives can. However, freeware

utilities are available on the internet that provide a similar function.

Q: Does my 2-bay RAX unit support RAID?

A: The models covered in this manual support only JBOD functional-

ity. However, the drives can be RAIDed in software, or RAX can be

attached to a RAID HBA for hardware RAID functionality.

Q: Why is my hard drive experiencing data corruption?

A: Many things can cause data corruption on hard drives, whether

they are inside your computer or inside an external storage

product. Malicious software, OS bugs, failure to properly discon-

nect external devices, or no reason at all. Data corruption or loss is

therefore not covered by warranty (this is the case with all rational

companies in the storage industry).

The ﬁrst thing to try is restarting both the computer and the

external device. If the data is still corrupted, try running built-in

OS utilities (such as Mac OS X’s Disk Utility First Aid) on the hard

drive. For best results, boot your computer with a Mac OS X Instal-

lation CD, and launch Disk Utility from the CD. When you reach the

Mac OS Installation program, you can run Disk Utility from one of

the menus at the top of the screen. From Disk Utility, you can run

“Verify Disk” and “Repair Disk” to ﬁnd and ﬁx any errors that may

be present in your Mac OS installation.

If the OS utility doesn’t help, you may need Data Rescue. This is a

great solution for recovering lost data from a hard drive which has

suffered data loss or corruption. If there is a true hardware failure

of your hard drive that prevents it from communicating with your

computer, there is no software solution in existence that can ﬁx

this problem. However, since we cannot tell you with any certainty

whether or not you are experiencing hardware failure in your

particular hard drive, we would encourage you to download a free

demo version of ProSoft’s Data Rescue from www.prosofteng.com.

It is limited, in that it only allows you to recover one ﬁle per session,

but it will tell you if it even sees any ﬁles.

Q: Will this product work with hard drives larger than 2.2TB?

A: Yes, assuming the rest of your conﬁguration (e.g. OS, BIOS, host

drivers) supports large volumes, this product is compatible with

drives larger than 2.2TB.
