Operating

Modes

Single Mode (Non-RAID)

In Single Mode, the installed drives

will appear individually as two

independent drives. This function can

be used if only one hard drive is

installed, or two different brands or

capacities of drive are being used.

RAID 0 - Spanning Mode

In Spanning Mode, two hard drives

will appear as a single, large drive.

Spanning is an array that is written

sequentially across two drives.

RAID 0 - Striping Mode

To operate in Mirroring Mode, two

identical hard drives (capacity,

brand and model number) must be

used. In Striping Mode, two hard

drives will appear as one large, single

drive, but will provide faster data

transfers, as data will be written to the

drives in a “column” effect. This form

of array splits each piece of data

across both drives in segments. This

form of RAID does not provide

redundancy or data checking.

RAID 1 - Mirroring Mode

To operate in Mirroring Mode, two

identical hard drives (capacity,

brand and model number) must be

used. This mode creates an extra

copy (or mirrored set) of the data from

drive one on the second drive.

Mirroring Mode provides data

redundancy that is useful in the event

that the primary hard drive fails,

allowing an instant replacement of

damaged data with the second set.

Please note: If RAID 1 mode is in effect, and you wish to change to single or

RAID 0 modes, please use the RIB Clean utility to clean the drives partition

table, located on the StarTech.com website, in the Downloads section. For

more information, please see the section titled Using the RIB Clean Utility.

Instruction Manual

Using the RIB Clean Utility

If you wish to switch from RAID 1 - Mirroring Mode to another operating mode, the RIB

Clean Utility must be used to prepare partition information.

To use the RIB Clean Utility:

1. Download the utility from the StarTech.com website (Downloads section), and save it

to the local computer.

2. Double-click on the RIBClean icon to launch the Utility:

3. Once the main Utility screen loads, click on Scan Disk.

4. Once Disk Scanning is complete, click on Clean RIB. Once complete, click on Exit.

Installation

Remove the cover of the enclosure by

unfastening and removing the screws

on the bottom of the unit (bottom side

is closest to the USB 2.0 and DC/IN

ports). Insert the screwdriver into the

remaining screw hole, and press

outward.

1. Mode Selection

With the cover removed, the jumpers

used for mode selection are exposed.

Please note that the jumper pin

numbers are denoted on the circuit

board.

To configure SAT3520U2R for RAID,

use the following jumper pin

selections. Once completed, please

leave the enclosure open, for hard

drive installation:

Instruction Manual

2. Drive Installation

Unfasten the screws on the internal

drive holder case, and pull backward

to release and remove the drive tray

from the enclosure.

Warning! If you are installing drives to be used in RAID 1 (Mirroring) Mode

with a drive that already contains data, the drives require separate installation

to prevent the data from being formatted. As such, please skip to Drive

Installation: RAID 1 (Mirror Mode). If neither of the drives contain data, you

can proceed with the following instructions (for Non-RAID or RAID 0

Configurations).

Please note that if you are configuring SAT3520U2R for RAID applications

(Mirroring Mode, Striping Mode or Spanning Mode), the installed hard

drives must be identical in brand, size and model number.

Non-RAID (Single Mode) or RAID 0 Configurations:

Insert both hard drives into the drive

tray, and secure them with screws

(provided).

Insert the drive tray (with both drives

installed) back into the enclosure.

Instruction Manual

Push the drive tray forward in the

enclosure, securing the connection.

Once the tray is firmly connected,

fasten the screws on the holder.

Replace the top panel of the

enclosure, and fasten the screws at

the bottom.

RAID 1 Mirror Mode

Insert the primary (containing data to

be mirrored) drive into the drive tray,

and fasten it to the tray with the

screws provided.

Insert the drive tray back into the

enclosure, ensuring the tray is

secured using the connectors.

Once secure, power on the enclosure.

SAT3520U2R will recognize the drive

as the master drive, and prepare it for

mirroring. Once complete, the error

light indicator of the second drive will

illuminate (denoted as HDD2 Error).

When this occurs, power off the

enclosure, and remove the drive tray

from the enclosure.

Instruction Manual

Insert the second drive (containing no

data) into the drive tray, and fasten it to

the tray with the screws provided.

Secure the drive tray to the enclosure

connections, and fasten the tray to the

enclosure using the screws removed

earlier (depicted on page 4)

Place the cover back on the

enclosure, and replace the screws

removed earlier.

Power on the enclosure.

SAT3520U2R will indicate that the

Rebuild function is under way (the

corresponding light will display

activity), as the data from Drive 1 is

mirrored onto Drive 2, and RAID 1 is

configured on the drives.

Please note that the Mirroring process

may take several minutes, depending

on the quantity of data being mirrored.

Please do NOT power off the

enclosure, until the HDD2 Error LED

is no longer illuminated.
