Frequently Asked Questions - TeraStation 6400DN BUFFALO
How do I set up the TeraStation 6400DN for the first time?
Connect the NAS to your router via Ethernet, power it on, then use the BUFFALO NAS Navigator software to find the device. Open a web browser and enter the IP address to access the initial setup wizard.
What RAID configurations are supported?
The TeraStation 6400DN supports RAID 0, 1, 5, 6, and 10. You can choose the mode during initial setup or change it later via the settings menu (note that changing RAID erases all data).
Can I replace a failed hard drive without losing data?
Yes, if your NAS is configured with a redundant RAID (e.g., RAID 1, 5, 6, or 10). Simply remove the failed drive and insert a new one of equal or larger capacity. The system will rebuild the array automatically.
How do I access files from a Windows or Mac computer?
Use file sharing protocols: for Windows, map a network drive using SMB/CIFS. For Mac, use AFP or SMB. You can also access via FTP or the web-based file manager.
Does the TeraStation 6400DN support remote access?
Yes, you can enable WebAccess or a VPN server for secure remote access. Alternatively, use built-in cloud sync services to sync folders with cloud storage.
Can I expand storage capacity later?
Yes, you can replace existing drives with larger ones or add external USB drives. For internal expansion, migrate to larger drives one by one if using a redundant RAID.
How do I back up my PC to the TeraStation?
Install BUFFALO Backup Utility on your PC and schedule backups to a shared folder on the NAS. Alternatively, use built-in Time Machine support for Mac.
What is the default administrator username and password?
The default login is admin for both username and password. You are strongly advised to change this during initial setup.
How do I reset the NAS to factory defaults?
Press and hold the Reset button on the front panel for at least 10 seconds using a paperclip. This will reset all settings and restore the device to factory state (excluding data).
What should I do if the NAS becomes unresponsive?
First, try a soft reboot via the web interface. If inaccessible, press the Power button briefly to shut down gracefully. As a last resort, unplug the power cord for 30 seconds and reconnect.
