NAS 3.0 Adapter Q & A

Q1. I connected the NAS 3.0 device to my network but cannot find the NAS 3.0 adapter using the utility provided in the installation CD.
A. There may be problems in the LAN that prevent the NAS 3.0 adapter from being detected on the network. To make sure the NAS is functioning properly, you may connect it to the LAN port of a stand alone computer (a computer that is not connected to the network). Be sure the computer is set up to obtain IP address automatically. Then run the installation utility on the computer to find the NAS 3.0 adapter. Once it is found, you should be able to enter the NAS management console by clicking on the CONNECT button on the utility program. This indicates the NAS 3.0 adapter is working properly.

Q2. I cannot see the NAS 3.0 device storage in my network.
A. Go to NAS 3.0 adapter management screen and check to make sure the NAS 3.0 adapter is set up with the same workgroup name for your network.

Q3: What is the default login name and password for the NAS 3.0 adapter?
A.The NAS 3.0 adapter default Login name: “admin”, default password: “admin”.

Q4. Can I connect an existing USB storage device with data already on it and share the content right the way?
A. Yes. Any USB storage device with existing data can be attached to the NAS 3.0 adapter. For drives with NTFS file system and have existing data, please follow the procedures below to prepare the drive prior to attaching it to the NAS adapter:

  1. Attach a blank NTFS formatted drive (hard drive or flash drive) to the NAS adapter
  2. Once the drive is detected, add the necessary SMB or WebDav user accounts
  3. Remove the drive from the NAS adapter and attach it to a Windows XP or Windows 7 computer
  4. Copy all the folders and the two hidden config files – SMBACCT.cfg and WebDav.cfg from this drive onto the root of the USB drive that you want to share
  5. Now attach the USB drive to the NAS adapter, wait for 10 – 20 seconds till the drive is detected by the NAS adapter
  6. Now add the folders that you want to share to each user and assign the READ/WRITE privilege
  7. To add more users, repeat step 1 through 6 again. DO NOT add more users directly to the drive via the NAS adapter if there are more than 18 folders on the root of the drive. This may result in corrupting the directory table and the drive may no longer be useable although the data is still good on the drive. To fix the corrupted directory table, attached the drive to a Windows XP or Windows 7 system, note the drive letter assigned when the drive is detected. Go to Windows Command prompt (go to Start, select run, enter ‘cmd’ and click OK), type CHKDSK  /f  X: and press ENTER. (X represents the assigned drive letter on the drive that you want to fix)

For drives with ExFAT or FAT32 files system, it can be directly attached to the NAS adapter without the additional preparation step as required for the NTFS drive. Whenever an USB storage device is attached to the USB storage port on the NAS adapter, a Public folder, a BT folder and two .cfg files will be automatically created in the root directory of the USB storage device. A GUEST account with full READ/WRITE privileges to the Public folder is also automatically created.

Another option is to attached the USB storage to the printer port on the NAS 3.0 adapter. All existing content in the USB storage will be all shareable immediately with READ only function. Please review the detail limitation and set up in the next Q&A below. In this situation, there is also no special preparation required for the NTFS drive.

Q5. Can I attached USB storage to the USB printer port on the NAS 3.0 adapter?
A. Yes. Any existing data on the USB storage device attached to the USB printer port is shareable immediately. There is no login or account set up needed to access the data on this drive over the LAN. However, the data can be accessed with READ only function. There is no control of user privilege to limit accessing a certain folder on this drive. There must also be a storage device attached to the USB storage port in order to share the storage device attached to the USB printer port. The drive attached to the USB storage port can be any capacity of 2GB of higher. So a small thumb drive can be inserted into the USB storage port to enable the sharing of the USB drive attached to the printer port without any complicated user account set up

The entire drive attached to the printer port is also shareable via WebDAV connection. You will need to enter 'Guest' as a user name to access the drive.

Q6. Can I remove the the USB storage device from the NAS 3.0 adapter and attach to another computer ?
A. Yes. The hard drive can be detached from the NAS 3.0 adapter and reconnect to any computer to be used as an external USB storage. Two .CFG files containing all the users and share folders set up information are created in the root directory of the USB storage by the NAS 3.0 adapter. Make sure these two files are not erased when the USB storage is connected to a computer.

Q7. I transferred some folders and files to the USB storage via USB connection to a computer. But the data does not appear when the USB drive is connected back to the NAS 3.0 adapter.
A. Check to make sure the folders and files are inside the PUBLIC folder or one of the folders created by the NAS 3.0 adapter.

Q8. I attached a brand new USB drive and the NAS 3.0 adapter cannot detect the drive.
A. Be sure the hard drive has been formatted with either NTFS, exFAT or FAT32 file system. The NAS 3.0 adapter does not have any formatting utility and also does not support storage device with other type of file systems.

Q9. What is the maximum file size that I can copy into the USB storage device?
A. This depends on file system

File System
NAS 3.0 adapter
NAS 2.0 adapter
NAS adapter
16 TeraBytes
16 ExaBytes
4 GigaBytes
127 GigaBytes
127 GigaBytes

Q10. If my NAS 3.0 adapter becomes non functional, can I just transfer the USB storage to a good NAS 3.0 adapter and do I need to set up the user and password information again?
A. Yes, the USB hard drive, once prepared by a NAS 3.0 adapter, can be transfer to another NAS 3.0 adapter. There is no need to set up users and password again as these information are stored in the two .CFG files in the root directory of the hard drive. If somehow these two files are corrupted, it will not be detected by the NAS 3.0 adapter. So it is a good idea to save these two .CFG files at at different computer or network storage as a backup.

Q11. Can I attached an USB hub to the NAS 3.0 adapter to have multiple hard drives on the Network?
A. No. The NAS 3.0 device does not support USB hub

Q12. Can I add more than one NAS 3.0 adapter to the Network?
A. Yes. You can add as many NAS 3.0 adapters as your Network can support. Each NAS 3.0 adapter will have its own unique IP address and appear as another network device on your LAN.

Q13. What kind of data transfer rate can I expect?
A.The transfer speed depends on the following factors: the speed of your Network, the performance of your hard drives and the file size. Following is the typical transfer rate that we see over a 1000 Mbps network and with a USB 2.0 storage containing a 2.5" SATA hard drive.

Q15. I can't make a USB drive larger than 2TB work with the NAS unit, why won't it work?
A. Older operating systems like Windows XP and the older "Master Boot Record" partition table they use are limited to 2TB of capacity. Most "retail" USB hard drives (drives sold under the manufacturer's brand already configured as USB external drives) implement a workaround in the enclosure's electronics to allow older operating systems to access the full capacity. This workaround is not compatible with the operating system running on the NAS unit.

Standard SATA hard drives larger than 2TB in capacity are known to work well with the NAS unit when installed in a generic USB enclosure or converted to USB using an adapter like the Addonics ADU31ESP. The NAS unit has been tested with RAID configurations on USB much greater in capacity than currently available 4TB hard drives.

For example you may want to read the product review from ANANDTECH on the Seagate 3TB GoFlex drive.

Q16. Can I attached an USB hard drive the the NAS 3.0 adapter without formatting?
A.For the NAS 3.0 adapter, no formatting is required. Any hard drive preformatted with NTFS, exFAT or FAT 32 file system is supported by the NAS 3.0 adapter.

Q17. Can I use backup software to make backup to the NAS 3.0 adapter storage?
A.Yes. We had tested the Acronis Enterprise, the Acronis Home Edition and GoodSync software.

Q18. How come my NAS 3.0 adapter busy uploading data while there is no FTP access?
A. If you have Bit-Torrent files stored in the BT directory, this file can be accessed by other users out in the internet and thus generating the upload traffic. This is how Bit-Torrent file works. You can download it from other computers out in the internet and someone else can also download the file from your system as well. The NAS 3.0 adapter does not have the option to turn off the Bit-Torrent to stop the file sharing. If you want to stop the Bit-Torrent file from sharing after your download, you will need to move the Bit-Torrent file outside the BT sub-directory.

Q19: How do I access the data from the internet without FTP?
A. The NAS 3.0 adapter comes built-in with a WebDAV server. You can access any information stored in the WebDAV server via the Internet connection from any PC or smart phone that has WedDav client software. Windows XP and 7 comes built in with WebDAV client. Free WebDAV client software are available for different PC platform, iPhone, iPAD and Android device.

Q20: Where can I find a third party WebDAV client software for my device?
A. Windows XP and later release has built-in WebDAV client support. There are reports of some problem with the WebDAV client on Windows 7. You may also consider using third part WebDAV clients. The following are samples of the free WebDAV clients software that we have tested:

Windows: Netdrive
MAC: Transmit
iPhone and Android - WebDAV navigator by Sean Ashton

Please note that Addonics does not provide support on the set up and any compatible issue of these WebDAV client software. You have to contact the client software publish for support.

Q21: Why can’t I upload files via LAN connection? Or I experience disconnection issues?
A. Please make sure the network configuration is connected properly and you have the access right (read & write) for the folders.

Q22: How do I reset the NAS 3.0 adapter?
A. By hardware: Press the reset button for 30 seconds and the NAS 3.0 adapter will reset to the factory settings.
  By software: Enter the NAS 3.0 adapter Management GUI, and select Maintenance/Factory defaults and click on the “reset” button. After seeing the message indicating that the reset is completed, click on the “reboot” button to complete the process.

Q23: How to setup the NAS 3.0 adapter to be in Daylight saving time?
A. The NAS 3.0 adapter does not support Daylight saving time setting.

Q24: I am not able to enter SMB folder with password via NAS 3.0 adapter using Windows XP.
A. Please update Windows XP to Service Pack 2 or above. After update if issue still resides, check your software firewall settings.

Q25: What is the default login name and password for the NAS 3.0 adapter?
A. The NAS 3.0 adapter default Login name: “admin”, default password: “admin”.

Q26: What Operating Systems does NAS 3.0 adapter Management software support?
A. Access to the Management GUI is OS-Independent. Any operating system with an internet browser can manage the NAS 3.0 adapter from the Management GUI.

Q27: How do I access NAS 3.0 adapter via the Internet?
A. If your NAS 3.0 adapter is using a fixed public IP, please perform the following steps.
1. Enter the Management GUI of NAS 3.0 adapter, and go to the WebDAV Server page to enable WebDAV.
2. Create User account and limits of authority
3. Forward the NAS 3.0 IP address to port 80 (the default port address) or other external port # if Port 80 is blocked.
3. Set up the WebDAV client software with the correct IP address of your router followed by /WebDAV/folder name that the user has been assigned.

Q28: What is the maximum number of users simultaneously able to access the NAS 3.0 adapter WebDAV server and Sambra server?
A. Support Samba server for up to 64 concurrent clients. Share Level Access (maximum 16 folders shared by root). For WebDAV, concurrent client connection not recommend to exceed 4 for best performance.

Q29. What are the maximum # accounts that I can create in the Sambra server and WebDAV server?


server type
NAS 3.0 adapter
16 accounts
16 accounts

Q30: What DHCP capabilities are available for the NAS 3.0 adapter?
A. You can setup the NAS 3.0 adapter as a DHCP server if there is no other DHCP Server existing in your Local Area Network. Otherwise, the NAS 3.0 adapter will automatically turn off its DHCP server function and become a DHCP client. For example, if you have installed a router with built-in (activate) DHCP Server, the NAS 3.0 adapter will automatically set itself as a DHCP client.

Q31: I can't create a mapped drive to a folder in a share on the NAS 3.0, but I can create a mapped drive to a folder in a share on a Windows PC. How do I map a drive to a folder on the NAS 3.0?
A. The NAS 3.0 doesn't directly support mapping to subfolders. It is possible to represent folders on the NAS 3.0 unit using a command line tool under Windows called SUBST. It will require an extra mapped drive for the share, though.
      For example, let's assume you want to use a folder called FOLDER  on the NAS 3.0 unit's PUBLIC share as drive X: - you can't map a drive letter directly to it, but if you map drive letter Y: (for example) to the PUBLIC share, you can open a command prompt window  and type the following command:

      Once you have done this, drive letter X: will then represent the FOLDER you wanted.
      NOTE: removing the mapped drive connection will break the connection for the SUBST drive but doesn't remove that drive letter automatically. Carrying this further in our example, to remove that drive letter X:, type in the following command:
      SUBST X: /D
      Executing this command is recommended before removing the mapped drive.
