WARNING! If you are installing drives to be used in RAID 1 (Mirroring)
Mode with a drive that already contains data, that drive must always be
installed first.
NOTE: 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.

Unfasten the two screws on either1.
side of the internal drive holder
case, and pull backward to release
and remove the drive tray from the
enclosure.

ensuring the tray is secured using the
connectors.
Once secure, power on the enclosure.3.
SAT3520U2R will recognize the drive as the master drive, and4.
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 tray5.
from the enclosure.
Insert the second drive (containing no data)6.

Driver Installation
Windows 2000/XP/Vista/7, Mac OS X, Linux
No driver installation is required for these operating systems, as
this drive enclosure is natively supported, so the drivers are already
installed.
How to Use
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
Striping combines multiple hard drives into a single large disk array.
The data is split evenly across both drives simultaneously. Read/write
performance is increased as a result, but failure of any one disk will
make the entire array unusable.
