Hard Drive Formatting Guide on Windows
Partition a volume
A volume must be partitioned before you may begin using the drives under the operating
system. The following sections describe the procedures required to partition a volume.
Note :
- Follow the step-by-step instructions below to complete the HDD partitioning and
formatting.
- Each HDD has to be partitioned and formatted respectively.
1. Right-click the“Computer” icon and select “Manage” from the pop-up window. From
the Computer Management window select “Disk Management” under Storage to start
formatting.
7
MH-3642RD-U3
4Bay RAID Storage Center
2. Right-click “Unallocated” and select “New Simple Volume”. If a New Simple Volume
option is not available, initialize the disk first. To initialize a disk, please check “Initialize a
Disk” at next section for guidance.
Note: In Windows XP, you will probably find “New Partition” instead of “New Simple
Volume”. They are basically the same concept; these two terms can be used
interchangeably.
3. Click “Next” to start the New Simple Volume Wizard.
8
MH-3642RD-U3
4Bay RAID Storage Center
4. Specify the partition size. The partition occupies the entire volume by default and then
click “Next”.
5. Assign a drive letter and click “Next”.
9
MH-3642RD-U3
4Bay RAID Storage Center
6. Name, format the partition, and click “Next”.

Initialize a Disk
If a New Simple Volume option is not available while right-clicking the “Unallocated” box,
then look to the left of the “Unallocated” box. Most likely you would see HDD(s) “Not
Initialized”. Initialize the HDD(s) and make sure you see “Online” before proceeding to HDD
formatting/partitioning.
1. Right-click the “Not Initialized” block to open pull-down menu.
11
MH-3642RD-U3
4Bay RAID Storage Center
2. Select “Initialize Disk”.
3. You will see a pop-up window below. Windows 7 provides options for “MBR” and “GPT”.
If the HDD capacity does not exceed 2TB, then “MBR” option is recommended. On the
other hand, “GPT” is recommended while HDD capacity is over 2TB.
12
MH-3642RD-U3

4 HDDs are accessible as one independent hard drive.
Sum of 4 HDD capacity
RAID 0
RAID: Block-level striping without parity or mirroring.
Capacity: multiply the smallest capacity by 4
RAID 3
RAID: Byte-level striping with dedicated parity disk
Capacity: multiply the smallest capacity by (4-1)
RAID 5
RAID: Block-level striping with distributed parity
Capacity: multiply the smallest capacity by (4-1)

RAID 1+0: Mirroring without parity, and block-level striping.
Capacity equals to the smallest HDD multiply 2
Note:
1. HDD1/HDD2 create a set based RAID 1: HDD1/2
HDD3/HDD4 create a set based RAID 1: HDD3/4
Two sets (HDD1/2, HDD3/4) create a set of RAID 0

Power Synchronization
This RAID Storage Center is able to detect the status of PC and turn on & off automatically.
a. PC power off
PC Power off
Power LED on, HDDs off, 4HDD LEDs off, Fan off
b. PC hibernates(sleep mode)
Note: When a system reaches sleep mode, the monitor and peripheral turns off while the
motherboard is still power on. In this case, HDD and LED will be still on.
PC Hibernates
Power LED on, HDDs off, 4HDD LEDs off
Note:
- To enhance power synchronization feature, do not turn off the main power of this device.
- Fan stops within 90 seconds after power synchronization initiated.

HDD Modes
 Reset the device is necessary when changing HDD Mode. Press “Raid Reset” button only
when the device is powered on & connected to a running PC. HDD pre-installation is
mandatory.
 Make sure to backup data before changing HDD mode since such practice requires HDD
reformatting and all data will be deleted.
 Detailed procedures to perform HDD Mode change as follows.
a. Install four HDDs into the storage center.
b. Connect the storage center to PC and have both devices powered on.
c. Adjust RAID switch correctly.
d. Pin and hold “RAID reset” button for 3 to 5 seconds to observe rapid blinking of four
HDD LEDs. The HDD mode adjustment completes when LED rapid blinking stops.
e. Initialize and format HDD(s) to complete operation.
 When using four HDDs with unequal capacity, users may experience capacity reduction
under RAID 0/3/5 and RAID1+0 configuration. Therefore, it is recommended to use HDDs
with equal capacity in order to utilize the application.
HDD
 Installing HDD(s) exceed 2TB is possible. However, make sure this device is operating
under Vista, Windows 7, Linux and Mac OS and activate GPT (GUID Partition Table) mode
when formatting this device to have it work correctly.
 Do not install or remove HDD while any HDD(s) is working.
USB & eSATA
 The equipped USB3.0 port is downward compatible with USB2.0
 eSATA host(PC) needs to support Port Multiplier function in order to have Individual
Mode(Single) operable thus 4 HDDs correctly recognized.
 If eSATA host(PC) doesn’t support hot swappable, and plug and play function, then please
pay attention to the sequence of powering on the storage center as follows
a. Connect eSATA cable when the storage center and PC are powered OFF.
b. Power on the storage center first and observe HDD Link LED(s) are light on
c. Power on PC
 Do not connect both USB & eSATA simultaneously! eSATA connection will be prioritized.
