Press and hold the "RAID confirmation button" key until the
enclosure shuts off.
Power on the enclosure again and wait for 20 seconds.
Go to disk management to initialize, partition and format your
array hard drives.
If you have more than 2TBs of hard drive volume, please select
GPT when initializing the drive.
Your array is set to go after partition and formatting.
NTFS has volume size limit based on different cluster size setting.
We suggest user to set cluster size as 64K when formatting a disk
volume over 2TB. For more information, please check Microsoft
Support. (http://support.microsoft.com/kb/302873)

There are several mode options for HFR2-SU3S2,
RAID 0 (Spanning), RAID 0 (Stripping), RAID 1, RAID 3, RAID 5
and RAID l 0.
The enclosure is NOT default to any of the above. So If you just
put hard drives in without setting a mode to use, the enclosure
will just turn off after a few seconds of turning it ON.
When using RAID function, HDDs with the same brand,
model and capacity is strongly recommended.
1. First install the HDD from up to down in the enclosure. Make
sure the PC is ON and ready to go, then power on the device.

Changing RAID mode may cause data lost, backup your data
before making changes.
Do not use hard drives containing data to create a RAID array.
Please refer to the instructions when switching the RAID mode,
otherwise the execution might fail.
When using RAID function, HDDs with the same brand,
model and capacity is strongly recommended.
When using RAID function, more than one HDD partition
is not recommended.
In RAID 1, HDD1 and HDD2 must be installed, otherwise the
PC (Windows / Macintosh) can not recognize the device.
The chart below tells you that the device still functions when
one HDD has error.
RAID 10
1. When one HDD has error, the device still functions well but
you may have to replace it with a new one immediately.
2. The chart below tells you that the device still functions
when two HDDs have error.

When the USB / eSATA cable is plugged out, the device goes to
sleeping mode automatically.
If the transfer rate is not normal, please check if the setting
of SATA disk jumper is 1.5 or 3.0Gbps.
Support USB transfer speeds of Low speed (1.5Mbps),
Full speed (12Mbps),
High Speed (480Mbps), Super Speed (5Gbps),
eSATA transfer speed (1.5~3.0Gbps)
To take the HDD out from the device, slightly press down the
handle of the tray and pull it out.

If users enable MBR by mistake, in order to clean the
partition table, you have to switch to another RAID mode
and do the RAID mode switch all over again referring to
Setup. Then go back to the RAID mode you want, repeat
the previous actions and enable GPT when initializing HDD.
Under Windows 10/11, users can enable GPT when
initializing HDD with a total capacity of more than 2TB.
Do not connect the device to the SATA on board port of the
motherboard. Either use SATA to eSATA PCI-Express or SATA
to eSATA PCI add-on card, otherwise the PC (Windows /
Macintosh) may not recognize the device.
Setting up motherboard's power management in S3 is
recommended. (For more details, please refer to the user guide
of motherboard BIOS setting).
If the device takes too long to initialize, please check if the HDD
is securely installed or update the eSATA host driver version.
Rebuild time is based on the capacity, e.g. it takes about
1 hour for 200GB.
For Macintosh users: the total capacity of more than 2TB could be
recognized only for the operation system is 10.4.11 Tiger or later.
for Macintosh users, under macOS X 10.12 or later, It's strongly
recommended not to have the same name for all the HDDs.
Interface of USB / eSATA can not be used at the same time.

closed the cover, simply press down the rib and the cover
will slowly release and open outwards.
Please do not attempt to pull the cover with something sharp.
Please enable GPT if the total capacity is more than 2TB
and enable MBR if the total capacity is less than 2TB.
Activate GPT if total volume is more than 2TB
Activate MBR if total volume is less than 2TB
