Common Questions about NST-400MX-S3R [#10102019]
I try changing the 400MX storage to RAID 1 mode and it will not work. What am I doing wrong?
Here are the steps:
a) Set the DIP switches to desired RAID 1 mode of operation
b) Connect to power, connect USB to 400MX and PC
c) Go into Disk Management in Windows (Disk Utility in Mac) and power on the 400MX
d) Wait for OS to detect the 400MX and show the two separate drives
e) When the drives appear, press and hold the reset button on the 400MX until both drives disappear (15-20 seconds), and then release the button.
f) A single disk will now appear and will need to be initialized. Initialize, create volume, and then format.
The switch setting is confusing? According to your manual is the white color ON or the black color ON?
The white color is the correct toggle.
Individual mode: 1-OFF 2-OFF
JBOD mode: 1-ON 2-OFF
RAID 0 mode: 1-ON 2-ON
RAID 1 mode: 1-OFF 2-ON
I installed two drives into the 400MX and connect to my system via eSATA and it is seeing only one drive. Why?
The design of eSATA connection is for one connection to one drive. If the eSATA port on your computer has support for Port Multiplier function you will be able to read/write on multiple drives. If you can only see one drive, your system eSATA port does not have Port Multiplier function.
What is Port Multiplier?
Port Multipliers are devices that allow a single SATA port to communicate with multiple drives. The Port Multiplier is transparent to the drives, but the host (computer) is aware that it is communicating with multiple drives. The Port Multiplier is the function of the SATA Host Controller. If the controller DO NOT support Port Multiplier function and it is connected to a hard drive enclosure with more than one drive, it will ONLY see one drive.
Where can I get eSATA that have Port Multiplier function?
eSATA card with Port Multiplier function comes in ExpressCard or an add-on card for your system. Some motherboard may have this function already built in to the board.
Since I am using JBOD/RAID 0/RAID 1 with 2 drives, I do not need Port Multiplier right?
Yes, you are right because after configuring the mode the two drives are combined into one and your computer system will see it as one drive, therefore you do not need Port Multiplier function.
I currently do not have a USB 3.0 port; can I use a USB 2.0 port for my 400MX?
Yes, you can. The USB 3.0 connection is backward compatible with USB 2.0 port, but the 400MX will run at USB 2.0 speed.
Do I have to use the same brand and model for two of the drives?
No, you do not, but it is good to have both the same.
Does this 400MX device require any drivers?
No, it does not require any special drivers. It is using built in drivers in the Operating Systems (Windows and Mac OSX).
Does the NexStar MX do RAID or JBOD?
The NST-400MX-S3R support individual (two single drives), JBOD (Concatenate drives), RAID 0 (Striped) and RAID 1 (Mirror) mode.
How do you interpret the LED lights on the NST-400MX-S3R?
Please refer to page 6 on the user manual for LED indicator.
If I have existing data on a drive, can I put this drive with data into the 400MX and create a RAID with the data intact?
No, the 400MX will erase the data during the initialize process.
Can I connect the 400MX USB 3.0 port to one system and the eSATA to another so that I can share the data on this storage with two computers?
No, it will work with only one interface at a time.
Will the 400MX goes to sleep when my computer it is connected goes to sleep?
Yes, if you are using USB 3.0 or eSATA.
Is the NST-400MX-S3R compatible with Windows 10 and OS X 10.10 or better?
Yes, the 400MX are compatible with both OS.
How long will the rebuild take?
It depends on your drive capacity. It is rebuilding at a rate of 250GB/hour.
Do I have to initialize and format the drives first before installing into the 400MX enclosure?
No, you do not. The Set mode function will erase the drive.
What is the maximum capacity of the drives that I can use with the 400MX?
Due to the ever increasing capacity of hard drives, the current size is 6TB or 8TB per bay.
Please check on our website or write to Technical Support for the inquiry.
Do you provide application software to monitor the status of the 400MX?
No, we do not. The LED is the only status for monitoring the health of the drives.
If RAID 1 HDD2 fails what must I do?
Power down the 400MX, remove HDD2, put in a new drive (similar or bigger in capacity), and turn it back on and let the rebuild take place. You do not have to do anything else.
How do I get eSATA to work?
a) Have everything disconnected
b) Reboot the computer
c) Make sure the hard drive is secure and properly connected
d) Proceed to connect the power to the device
e) Turn on the power and let the hard drive spin up for about 10-15 sec.
f) Connect the eSATA to the device and then to the computer
g) Computer should automatically detect the hard drive and mount it.
h) If hard drive is not mounting, please go ahead and check the device manager to refresh the device list. The hard drive might need to be formatted. Make sure you back up all valuable information on the hard drive before continuing. (formatting will erase all the information on the hard drive)
I wanted to connect my 400MX to my Router, can I use DLNA with this device?
We have not tested with any router, but it should work as a storage device, it have nothing to do with DLNA, and will not have managed capability of DLNA.
Can I get S.M.A.R.T data off the drive in the 400MX?
There are some 3rd party tools that lets you access SMART on the 400MX.
My RAID disk are almost full, Can add a bigger disk one at a time to grow and increase the capacity. Like my 1TB mirror pair, I remove one and add in a 4TB and let the rebuilding complete before adding the second 4TB so that I can have two 4TB drive in mirror mode?
This RAID-in-a-box cannot grow. If you need to upgrade the drive, you need to backup the data, create a new RAID for your 4TB drives and restore your data.
I need further help that is not listed here, where can I get help?
Write to technical support at firstname.lastname@example.org they can help you with other questions or assistance that are not listed here.

How to prepare a New Storage, Hard Drive, or SSD for use with a system? [#33406]
There are two set of instruction. One for Windows OS and another for OS X. Please use the right set of instruction for your System.
>>>>>> 1) Preparing a new hard drive for use with Windows 7/8/10 OS <<<<<<
NOTE: If you have important data on this drive, DO NOT go any further, please backup your data before you continue. These steps will erase ALL your data on the drive.
For Windows 7, hold the Windows logo key on your keyboard and press “R” (Winkey+R). This will launch the Run the utility. Type “diskmgmt.msc” inside the text box and press Enter. This will open the Windows Disk Management utility. This is where you can format, create, and delete hard drive partitions.
For Windows 8/8.1/10, hold the Windows logo key on your keyboard and press “X” (Winkey+X). This will launch a popup window and select disk management.
Usually, the Initialize Disk Wizard will appear automatically when you open Disk Management. If you have more than one blank drive that needs to be initialized it will list them. Make sure that there is a check in the box of the drive that needs to be initialized, select check MBR if your hard drive is smaller than 2TB, if it is greater than 2TB, please check GPT and then left-click on the Ok button. If the wizard does show up, go to step 5. If the wizard does not show up, please see the note and additional images directly below.
Critical: If your hard drive is greater than 2TB in capacity, you need to use check GPT(GUID Partition Table), if it is smaller, select MBR.
Note: If you do not see the Initialize Disk wizard, manually start the initialization. The drive that needs to be initialized should have a little circle with a red arrow pointing down like in the image below.
When you find it. Right-click on the red arrow and choose Initialize Disk.
There are two mode of initializing a new drive using MBR or GPT. If your hard drive is greater than 2TB, you need to use check GPT, if it is smaller, select MBR.
The drive is now initialized. The disk should have a black bar and say that it is Unallocated. You should now be able to create a partition and format the hard drive.
Now right click the unallocated space and click create a New Simple Volume shown below:
Follow the on screen wizard by clicking Next
Specify your volume size, if you are not sure use the default, and now click Next
Assign a drive letter to the drive, if you are not sure use the default and click Next
Format the partition and name the volume, if you are not sure use the default
Now click Finish and it will start formatting the drive to get it ready for use.
Once the formatting is done, your system will report the presense of a new drive with an assigned drive letter. You can begin using the storage.
