http://eshop.macsales.com/item/OWC/MEP2BAYM15/

•If the Mercury Elite Pro Dual mini is daisy-chained oﬀ of another FireWire device

instead of being connected directly to a computer, you must use the 12V power

adapter. Attempting to bus-power the Mercury Elite Pro Dual mini using the FireWire

port of another device could cause damage to one or both devices and should not

be attempted.

•Even when the power 12V power adapter is not connected, the on/oﬀ switch must

be in the ‘on’ position in order to use the Mercury Elite Pro Dual mini.

•Only one interface (USB or FireWire) at a time can be used.

•For the safe removal of your drive and to ensure that no data is lost, always eject or

unmount the drive from your operating system before powering oﬀ.

OWC MERCURY ELITE PRO DUAL MINI SYSTEM SETUP

SYSTEM SETUP

2.1 QUICK START

If you purchased the Mercury Elite Pro Dual mini as an empty enclosure, see Section 2.2,

Assembly. If you purchased the Mercury Elite Pro Dual mini with drives already installed,

the OWC Drive Guide formatting utility has been installed on your Mercury Elite Pro Dual

mini. Follow these steps to use the OWC Drive Guide to format your Mercury Elite Pro

Dual mini for Mac OS X (10.4 and later) or Windows (XP and later).

1. Connect your drive to your computer using the proper cable, then turn on your drive.

If you prefer to use a diﬀerent formatting utility, do so at this time and skip the rest of

these instructions.

2. Your drive will show up as “OWC HD”. Open your drive to view its contents.

3. Open the “Macintosh Setup” or “Windows Setup” folder, depending on the computer’s

operating system, then double-click the OWC Drive Guide application.

4. Follow the simple on-screen instructions to complete the formatting process.

5. Once the formatting is ﬁnished the drive is ready to use.

2.2 ASSEMBLY

NOTE: The following instructions show how to open the Mercury Elite Pro Dual mini

in order to change the RAID settings and install drives. If you purchased the Mercury

Elite Pro Dual mini with drives already installed, follow the assembly instructions through

step 3 to gain access to the DIP switches that control the RAID settings. If you wish to re-

move or replace the drives after the expiration of the original warranty, you may do so at

that time. Removal of the pre-installed drives before the expiration of the original

warranty of the Mercury Elite Pro Dual mini will VOID the warranty.

1. Use a Phillips screwdriver to remove the two screws at the rear of the enclosure, as

circled below in red.

OWC MERCURY ELITE PRO DUAL MINI SYSTEM SETUP

2. Tilt the Mercury Elite Pro Dual mini up

at the front to allow the back plate to

fall free. Note the three DIP switches

in the blue block to the left of the on/

oﬀ switch. You will use these switches

to conﬁgure the desired RAID mode.

For now, set aside the back plate and

continue to step 3.

3. Gently push on the inner chassis

that was exposed by removing

the back plate. The inner chassis

should slide easily out of the

outer enclosure. Once there is

enough room at the front, as

shown to the left, you can pull

on the front of the inner chassis

to remove it fully.

NOTE: You are now able to access the

DIP switches to change the RAID mode

of the Mercury Elite Pro Dual mini. See

Section 2.3, RAID Settings for in-

structions on how to change the RAID

mode.

4. Once the inner chassis has been re-

moved from the outer enclosure,

note the two SATA connectors on

the right. There are also eight screw

holes: four through the metal on the

left and four through the green cir-

cuit board on the right. These are the

items that you will use to secure your

drives to the inner chassis.

OWC MERCURY ELITE PRO DUAL MINI SYSTEM SETUP

5. Place your drives in the

inner chassis as shown to

the right. Press each drive

toward the rear of the inner

chassis to make sure that

the drives are fully seated in

the SATA connectors.

6. Use one hand to

hold both drives down,

then ﬂip over the inner

chassis. There are eight

screw holes on the bot-

tom of the inner chassis,

as circled in red.

OWC MERCURY ELITE PRO DUAL MINI SYSTEM SETUP

7. Using a Phillips screwdriver,

insert the eight included

screws into the screw holes

to fasten the drives to the

inner chassis, as shown.

When this is done, ﬂip the

inner chassis back over.

8. Slide the inner chassis back into the

outer enclosure. Note that the inner

chassis can slide in either end of the

outer chassis, but the rails on one end

of the outer chassis are notched, as

shown to the left. This allows the back

plate to sit ﬂush when attached.

9. Using a Phillips screwdriver, attach the back plate as shown. The Mercury Elite Pro Dual

mini is now assembled and ready to be used.

2.3 RAID SETTINGS

WARNING: Changing the RAID mode will destroy the

data on the drives. Be sure to back up your data rst! See

section 3.2 for information on proper backup strategies.

2.3.1 Changing the RAID Mode

The RAID mode on the Mercury Elite Pro Dual mini is controlled by a set of three DIP

(dual in-line package) switches located in a blue block inside the enclosure. Section

2.2, Assembly shows how to access the DIP switches.

The switches are labeled 1, 2, and 3, and the blue block has the word ‘ON’ at the top.

The ‘ON’ position for each switch is toward the word ‘ON’, while the ‘OFF’ position

for each switch is toward the numbers. The following chart shows the switch posi-

tions that correspond to each RAID mode. See Section 2.3.2, RAID Modes for more

information on each RAID mode that can be used.

2TB MODE — Switch #1 has no eﬀect on the RAID mode. Instead, it controls the 2TB

volume limitation. When switch #1 is in the OFF position, the total capacity of the

drives is limited to a maximum of 2TB for compatiblity with older operating systems.

NOTE:

•If setting switch #1 to ON does not initially allow volume sizes to exceed 2TB, do the

following: keeping switch #1 in the ON position, change to a diﬀerent RAID mode,

then turn on the Mercury Elite Pro Dual mini. Format the new RAID volume, then

shut oﬀ the Mercury Elite Pro Dual mini, change to the desired RAID mode, and turn

on the Mercury Elite Pro Dual mini.

•When 2TB mode is enabled, PowerPC Macs and Intel Macs introduced before 2008

cannot use the OWC Mercury Elite Pro Dual mini as a startup drive over the FireWire

connection. This is a limitation of these computers. Mac models introduced in 2008

and later are fully capable of using the OWC Mercury Elite Pro Dual mini as a startup

drive over FireWire, even with 2TB mode enabled. Note that this only aﬀects FireWire

booting. All Intel Macs are still able to use the OWC Mercury Elite Pro Dual mini as a

startup drive over USB, regardless of whether 2TB mode is enabled.

OWC MERCURY ELITE PRO DUAL MINI SYSTEM SETUP

2.3.2 RAID Modes

Span Mode:

The drives show up as one large single volume. The total size will depend on the

drives installed; you can use drives of diﬀerent capacities. A span is an array (not RAID)

in which the data is written sequentially across the drives. This combines the capaci-

ties of the drives, but it does not provide any performance or redundancy beneﬁts.

RAID 0 “Drive Striping” Mode:

The drives show up as one large single volume with a size equal to the combined

capacities of both drives. RAID 0 is used when speed is the primary objective, but it

does not have any redundancy for protection. Data is alternated very quickly across

both drives to gain speed by distributing the workload. This allows for the fastest data

transfer rates, but if one drive fails, the whole array can become corrupted and data

will be lost. Always maintain a backup of your data!

RAID 1 “Drive Mirroring”Mode:

The drives show up as one volume with a size equal to the capacity of one of the two

drives used in the array. RAID 1 copies (or “mirrors”) a set of data from the ﬁrst drive to

the second drive. This is useful when reliability and redundancy are more important

than capacity. When one drive fails, it can be replaced and the data will be rebuilt

automatically.

2.4 DRIVE FAILURE

In the event that one of the drives fails, the corresponding drive LED will turn solid red.

If the Mercury Elite Pro Dual mini was conﬁgured as a RAID 0 or span, the data on the

array is lost and the volume cannot be used. In a span, only the data stored on the failed

drive is lost, although data recovery software will be required to recover the data from

the other drive in the span.

If the drive was part of a RAID 1 array, then it can be replaced. In the meantime, the data

will remain accessible through the other drive in the RAID 1 array. If the Mercury Elite

Pro Dual mini was purchased with drives already installed and it is still under warranty,

see Section 3.4 for information on how to contact OWC technical support. If the unit is

outside its warranty or was purchased without drives, follow the instructions in Section

2.2 to access and replace the failed drive. After the failed drive is replaced, the RAID 1

array will be rebuilt automatically. This process may take several hours to a day, based on

the capacity of the drives. NOTE: The failed drive must be replaced with a drive that is

identical in model and capacity.
