Frequently Asked Questions - TS4400D BUFFALO

What is the Buffalo TS4400D?

The Buffalo TS4400D is a 4-bay NAS server from the TeraStation 4000 series, designed for network storage and file sharing.

How many hard drives does the TS4400D support?

It supports up to four 3.5-inch SATA hard drives. At least one drive is required for operation.

Do I need to use new hard drives?

You can use new drives or existing drives that have been completely wiped (all partitions deleted). The drives must be un-partitioned.

How do I start the initial setup?

Insert drives, connect power and network, move the boot switch to USB, insert a prepared MicroSD via USB adapter, then power on. Follow the on-screen prompts.

What if I boot from HDD instead of USB?

The unit will show 'boot from HDD1' and stop. Turn off the unit by holding the power button, then repeat the setup steps starting from step 2 (boot switch to USB).

How do I format drives on the TS4400D?

After initial boot and software installation, access the admin interface via NAS Navigator or IP address. Under 'Drives' select Format Disk and choose XFS file system.

Can I create RAID arrays?

Yes, once all drives are formatted, you can create RAID arrays (RAID 0, 1, 5, 6, 10) via the admin interface. RAID is not created automatically.

How long does formatting take?

Formatting each drive takes approximately 8 minutes depending on capacity. The status in the admin page will change to 'Formatted' when done.

What is the RAID sync process?

After creating a RAID array, a background consistency check runs (status shows 'Syncing'). It can take up to 24 hours but the unit remains fully operable.

What should I do if the display shows a red warning?

A red display usually indicates unformatted drives or missing disks. Format all drives, or if no drives are installed, the unit will show 'boot from HDD failed'. Insert drives and restart.

USER MANUAL TS4400D BUFFALO

The TS4000 series will not work without disks. Please prepare 1 or more un-partitioned HDDs for the setup process. Use either new HDD(s) or delete all partitions (and therefore all data) with a partition editor before you start with existing HDD(s).

Step by step

1. Mount one or more HDDs to a frame and insert it in the TeraStation™

If you use just one drive you will have a brief warning for missing HDDs and afterwards the TeraStation™ will operate normally.

If you use more than one drive: The first HDD is mounted and will work normally and the other HDDs are mounted but not yet formatted. The display will therefore turn red and the status LEDs of all unformatted drives will show red as well.

The warning, red display, and red LEDs will remain until you finish formatting all HDDs.

1. Now please install the NAS Navigator on your computer and click 'Refresh' to reveal your new TeraStation™ 4000. Right click on it and select 'Settings'. A browser window will launch the admin interface. It's also possible to access the admin interface by entering the TS4000 series IP address (shown on the TS's display) directly into a browser window.

TeraStation™ 4000

Setup Guide

1. Format all unformatted HDDs via the admin interface. Once formatting is completed the status in the admin page will change to 'Formatted' please wait to see this before continuing, depending on HDD capacity this could take approximately 8 minutes per drive.

Setup Guide

1. After formatting, the Raid option is available. Please note: the setup process will not automatically create Raid. Once all your drives are formatted, please create the Raid or Raid Array that best suit your needs.

10a. After creating Raid 1, 5, 6, 10 (availability depending on number of disks installed) the TeraStation™ will automatically begin a Raid check.

10b. The status shows 'Syncing' during the Raid check while the consistency of the file system is confirmed. This process can take up to 24 hours. However, please note, TeraStation™ is fully operable during this time as the Raid check is performed in the background.

1. Once your Raid is created, next create folders according to your needs.

Notes:

If you boot the TeraStation™ without an HDD installed it will stop with a warning and red display with the message that booting from HDD failed. In this case, please switch off the unit with a long power button press and start from step 1 of this set up guide.
If instead of booting from the USB you boot from HDD (skipping step 3) the unit shows status as "boot from HDD1". In this case, please switch off with a long power button press and continue with step 2.
