Thank you for purchasing the Cavalry dual-bay USB 2.0
RAID dock. The EN-CAHDD2B-D was designed for
ultimate exibility. The multiple RAID settings allow
users to have several discrete RAID arrays, using
multiple disks, and still retain the ability to setup and test
new drives on-the-y. The automatic disk-duplication
feature allows you to create sector-to-sector backup
images of entire disks. The Plug and Play design means
that there are no bothersome drivers to install or update.
Just plug in your internal SATA drive(s) and congure
them in the disk management utility of your choice!
Up to 60MB/S Maximum Transfer Speed
USB 2.0 for Broad Multi-OS Compatibility
Up to 4 TB Total Capacity (Depending on Your OS)
Automatic Disk Duplication via RAID 1
RAID 1, RAID 0, JBOD and Spanning modes
Hot-Swappable
2.5” and 3.5” SATA II drive support
With the price of hard disks falling at ever faster rates, it has
become common for average computer users to have multiple
disks; both used and unused. The EN-CAHDD2B-D RAID
dock allows you to put those disks to work. For system
builders who can’t afford down-time caused by faulty OS
drives, the ultra-simple RAID 1 disk-duplication feature allows
you to make complete duplicate disks without connecting to
your computer! The hot-swappable dock design allows you to
cycle through as many disks as you like, in mere seconds; all
without restarting your PC or Mac!

This really isn’t a RAID mode at all. JBOD simply allows you to see each drive separately within either or both bays. There is
no performance advantage to JBOD. But, it is very useful when transferring data from one drive to the next; or when you need
to error-check individual drives within your disk management utility. Plus, JBOD does not change the le system the way the
other modes do. This makes it a safe bet if you are unsure of what mode you should use.
JBOD Mode = Just a Bunch Of Disks.
RAID modes and terminology can be a little confusing to the un-initiated. Rather than try to explain the exact mechanisms that
underlie each mode, we will describe each one in terms of what they can do. Then, you can carefully choose the appropriate
mode for your application.
This mode basically duplicates all of the data from one drive onto the next. In other words, it “mirrors” the source drive. This
is by far the preferred mode for a RAID array. It provides security for all of your source-drive’s data in the form of a true
automatic backup. The catch is that your storage capacity is limited to that of the source drive. You will also need to verify that
each disk you intend to use in this array is the exact same make and model.
RAID 1 Mode = Mirrored Drives.
This is only recommended for those people who absolutely must have the absolute maximum in transfer speed and storage
capacity. This mode is easily capable of exceeding the speed limit of USB 2.0 (roughly 60 MB/s). Likewise, it gives you access
to the full capacity of both disks combined. So, what could possibly be bad about that? The problem is this: if one drive dies,
all of your data will be lost. In order to safely use RAID 0, you’ll need a third separate drive in which to backup your critical
data. You will also need to verify that each disk you intend to use in this array is the exact same make and model.
RAID 0 Mode = Striped Drives.
This also is not exactly a RAID array. Spanning joins two drives into one big disk that has the capacity of both disks combined.
Unlike RAID 0, there is no speed increase from BIG mode. You can also use different sized disks in a Spanning array. But as
with RAID 0, if one drive fails, the entire BIG volume will be lost, along with any potential data. You’ll probably want a third
separate drive in which to backup your most critical data.
Spanning = BIG Drives.

DESCRIPTION OF RAID-MODES

In Windows, they call it “Disk Management”. In Mac, they call it “Disk Utility”. Despite having different names and
appearances, both Windows Disk Management and Mac Disk Utility do basically the same thing: they allow you to create,
modify and delete any storage volume connected to your computer.
In order to get the most out of your EN-CAHDD2B-D dock, you will need to become intimately familiar with your disk
management utility. Please refer to a detailed glossary on our website of the terms and explanations of the functions and
procedures you will need to understand [http://www.cavalrystorage.com/manuals.aspx]. It’s generally a good idea to keep
your disk management utility continuously open while you are setting up your dock and the disks within it.
How to Find Your Disk Management Utility
Windows: Navigate to Disk Management: Start Menu>right-click (My) Computer>select “Manage”>select Disk
Management.
Mac: Click an empty space on your Desktop. Then select (from the top of the screen) Go>Utilities>Disk Utility.
“Seeing” Your New Disk in the Disk Management Utility
In Mac, this is a pretty straight-forward affair. Just look at the left-hand column, and search for a newly added disk with the
term “DMI” or “USB” in it’s title.
Windows arbitrarily assigns a “Disk Number” to every new disk that is connected; even if the disk does NOT show up in
(My) Computer. “Disk 0” is always your system or C: drive. Your Cavalry drive will appear somewhere beneath Disk 0. It
will be given a number, like Disk 1 et al. You will probably only be able to recognize it by its size, which will be a little bit
less than the quoted drive size. If a connected disk does not appear here, the disk is probably defective. See the
troubleshooting FAQ for details.

Connect the Cavalry power supply.*
Connect the USB cable to a port on your computer that you
have used recently and know to work well. Take this time to
temporarily eject and disconnect any other external storage
devices you have. This will make it easier to nd your new
Cavalry dock.
Insert the hard drives that you are going to
use into the dock.** Make sure that you handle
them very carefully. Check that they are rmly
inserted into the dock.*** Be sure that you never touch any exposed circuitry or data ports
on the drive or the dock. Hard drives are very fragile devices!
Proceed to the Installation Guides below depending on the RAID-Mode of your choice.
A)
B)
C)
D)
*Note: Take a moment to label your power supply with the Cavalry Model # of your unit. A piece of light-colored masking tape
or an address label works great, and can save you tons of time and frustration down the road. Just make sure it is attached well.
**Note: Depending on the drives used when powering on, allow up to 30 seconds for both drives to spin up to speed.
***Note: Ensure a proper connection when inserting a drive by putting it straight down and not tilting it. If a drive is not being
detected, turn off the dock then remove and re-insert the drive.
Caution: Removing the hard drives from the dock while it is on may result in data loss.
With the dock powered-off, set the RAID-Mode selector switches to JBOD mode
shown in the image on the right.
Turn the dock on. Proceed to one of the next two steps, depending on whether your disks
already have data on them.*, **
Installing Disks with existing data: If you’re installing a disk with data already on it, look for your drive directly in
(My) Computer. If it does not show up, it may simply need to be assigned a new drive letter. It may also need to be
formatted to a different le system or may even have developed a fault since it was last used. Your disk
management utility can perform all of these functions as well as error-checking. See troubleshooting for details.
Installing Blank disks: If you’re installing a blank disk(s) skip ahead to the Initialization section (Step 3 - Page 7).

2STEP 2: JBOD MODE
JBOD installation is almost the same as installing a disk inside of your desktop computer. That is, once connected, you
will need to navigate to your disk management utility in order to locate the disk. There, you can prepare it for use with
your OS. If your disk already has data on it, JBOD is the preferred mode to use.

Power the dock off. Both disks should still be in the dock from your JBOD test.
Set switches to RAID 1 mode shown in the image on the right.
Power-on the dock.
Check for 1 unallocated disk in your disk management utility. Now you are ready to
partition and format that disk. As you do so, the invisible “mirrored” disk will receive
all of the same data that the visible “master” disk does.
See the Initialization section for specic formatting and partitioning instructions for your operating system.

There are two ways in which you can use RAID 1:
Create a new RAID 1 array using blank disks.
Duplicating a source disk which already has data on it.
Creating a New (Blank) RAID 1 Array
The process for creating a (blank) RAID 1 array is very simple. Just make sure that each disk is functioning in
JBOD mode rst. The two disks should be the same make and model number. If each disk appears as a separate
blank or “Unallocated” volume within your disk management utility, then they should be ready to create an
array.
Power the dock off. Both disks should still be in the dock from your JBOD test. Remove the blank disk only. The
EN-CAHDD2B-D will set whichever disk you insert rst as the “source” disk.
Set switches to RAID 1 mode shown in the image on the right.
Power-on the dock, and wait for only one disk to appear in your disk management
utility. This is the source disk.
Now with the dock still on, you can insert the blank or unallocated disk into
the empty slot. The second disk to be inserted automatically becomes the “destination”
or “mirror” disk.
Wait an hour or more (depending on the size of your drives) for the “destination” drive to nish automatically
copying all of the data from the “source” drive. After that time has elapsed, you can power the dock down and reset
it to JBOD mode.
Windows users may need to toggle the destination disk “Online” (using Disk Management) in order to access the
data on the disk.** If both disks appear with identical information on them, you know the RAID 1 copy procedure
was successful!***

D)
E)
F)
Duplicating a Source Disk Using RAID 1
Before you begin, make sure that each disk is functioning in JBOD mode rst. Then, check the data on the
source disk. The destination disk should be blank or “Unallocated” and, ideally, should be the same make and
model number.* If both disks appear in your disk management utility, you should now be ready to duplicate.
* At the very least, you must use another drive that has the same capacity.
**Some users may also need to assign a new drive letter to the destination disk, before Windows will allow you to access it.
***If you would like to continue using your RAID 1 array, simply power the dock down, and reset it to RAID 1. Now when you power the dock
on, it will continue to mirror the destination drive whenever you add new data to the source.

! Only blank or unallocated disks can be used to setup a RAID 0 array!
Power the dock off. Both disks should still be in the dock from your JBOD test.
Set the switches to RAID 0. See the picture on the right.
Power-on the dock.
Check for 1 unallocated disk in your disk management utility with a size close to that of your combined RAID 0
drives. Ex.: if you use 2 x 1TB drives, look for a single 1.8 TB unallocated drive. Now you are ready to partition
and format that disk. As you do so, the data will automatically be spread accross each disk in equal parts. This
makes for a very large, very fast array!

Windows:
Navigate to Disk Management: Start Menu>right-click (My) Computer>select “Manage”>select
Disk Management.
Once in Disk Management, look for your drives in the bottom-right window. You may have to scroll
down to nd it. The disk(s) will most easily be recognized by their size. Ex.: If you are initializing
a 1 TB drive, look for a drive that is close to the same size; like 931.51 GB. Once you’ve found it,
take note of the disk number.
If the Initialization Wizard does not appear, right-click the disk number, and then select the “Initial-
ize” option. If this option is not available, click the white box immediately to the right and select
“New Partition” for XP and “New Simple Volume” for Vista/ 7.
Select “MBR/Primary Partition” and “NTFS” for XP, or for drives that are smaller than 1TB. For
later versions of Windows (7 and Vista), select “GPT/GUID” and “NTFS”, or for drives that are
larger than 1 TB. Caution! GPT/GUID is not compatible with Windows XP!
Let Windows select a drive letter, as well as the rest of the options. Then press “Finish”. Double-
check that Windows assigned a drive-letter to your new drive(s). Otherwise, you will not see the
drive(s) in (My) Computer.
Now, look for your drive-letter(s) in (My) Computer and enjoy your new drive!
Mac OS X 10.4.0+:
Look for the drive in Disk Utility: Click an empty space on your Desktop. Then select (from the top
of the screen) Go>Utilities>Disk Utility.
Once in Disk Utility, look for your drive in the left-hand column. It should be easily identied as a
USB or DMI drive of a size close to it’s stated size. Ex.: If you are Initializing a 1TB drive, look for
a drive that is close to the same size; like 931.51 GB.
Click on the rst entry for your Cavalry drive; the one closest to the top.
On the right, there will be a row listing operations you can perform on your drive. Select
“Partition”.
Now select “Volume Format>Mac OS Extended (Journaled)”.
Click “Options,” and select “Apple Partition Map”.
Click “Partition”.
Check for your drive in Computer and/or the Desktop and enjoy your new drive!

Solid Green: A healthy, functioning HDD.
Flashing Green/Red: The connected HDD is writing or formatting.
Solid or Flashing Orange: The connected HDD is attempting to access
the host PC.
Solid or Flashing Red: The connected HDD is unhealthy or ofine.
No LED: No HDD is connected, or the HDD is in-operational.
I can’t see my drive(s)! If you have followed all of the above steps, and your drive is operational, you should see it in your
disk management utility. If you can’t, then check the dock using a known-working drive in the same slot. If that drive
appears when inserted into the same slot, the previous drive may be defective. If you don’t have another drive, plug the
drive in question into your computer’s motherboard. Look for it in your disk manager application. If you still can’t nd it
after this, you probably have a malfunctioning drive.
I can see my drive on my motherboard, but not in the dock. If this is the case, there may be a problem with the USB
port on your computer. Try connecting the dock to a different computer. If it shows up there, you probably have a bad port
on the original computer. If it doesn’t you may have a faulty dock. In that case, please contact Customer Support by email
or phone in the Contact Us section (Pg. 9).
I see the drive in my disk management application, but not on (My) Computer/Desktop. This is usually because the
drive was not initialized using the procedure described in Installation Guides. Windows users may need to change or
assign a new drive letter. It may also mean that the drive is recognized by your computer but uses a different le
system from another OS. You would then need to remove all the data from it and then format it as described in Initializing
Your Blank Array (Pg. 7).
How do I assign a drive-letter (Windows only)? Go to Disk Management and right-click the white box next to your drive
#. Select “Change Drive Letter or Path”. Take note of the assigned drive-letter and look for that letter in (My)
Computer.
I see my drive but it’s “Ofine”? Just right-click the disk number and select “Online”.
My drive doesn’t seem to t. This is probably because you are using an obsolete IDE drive. Our authorized parts retailer
sells an enclosure made especially for IDE. Please email us at customersupport@cavalrystorage.com for more information.
How do I create a drive that can be used on both Mac and Windows? You need to format a drive specically with
the FAT32 le system. This can most easily be done on a Mac, in Disk Utility. Just select the drive you want to use. Then
select “Erase>MS Dos (Fat)> Erase…” Once created, this disk will be usable by both operating systems!
But I can see my Windows disk on my Mac (or vice versa)! Yes, you can often see a Windows disk on a Mac or a
Mac disk on Windows. You may even be able to pull les off of it. But, you WON’T be able write to that disk unless
it is formatted to FAT32. This goes both ways.
How do I check the health of my slow or unresponsive disk(s)? In Windows, you right-click the rectangle next to your
disk number and select Properties>Tools>Check Now. This will also give you the option of repairing any corrupted data
automatically. Also within the same window, you can select “Defragment Now”. This can make a HUGE improvement
with older drives! In Mac, select your disk from the left-hand column. Then, choose First Aid>Repair Disk Permissions.
This may take some time. Once it’s nished, it will tell you the status of the repair. Your disk should be a lot faster and
more stable now!
WARNING! Always switch USB cables as your
rst troubleshooting step for all of the situations
below. We suggest that you simply unplug your
USB printer cable and plug it straight into your
dock, putting your original cable aside. That
allows you to use a known-working cable and
a known-working USB port on your computer
and eliminate those possibilities before you
even begin!
