Can You Recover Files from a Buffalo External Hard Disk?

Generally speaking, it’s possible to recover data from any Buffalo external data storage, but the steps you need to follow are determined by the model of your storage device.

That’s because Buffalo sells both traditional external hard drives (called MiniStation) and Network-attached Storage (NAS) devices that provide data protection by combining multiple individual drives into one RAID array (called DriveStation). For example, the DriveStation Quad supports up to four hard drives, giving you the ability to easily combine them into a RAID 0, RAID 1, RAID 5, or RAID 10 array.

While MiniStation external hard drives can be recovered just like regular internal hard drives using just about any data recovery tool, only more advanced tools can recover data from DriveStation RAID arrays. Alternatively, it’s possible to recover each RAID drive individually, but a tool that supports the correct file system or RAW recovery (disregarding the file system and focusing only on data) is necessary.


Buffalo also sells TeraStation and LinkStation NAS devices aimed at enterprise customers. Both TeraStation and LinkStation products can be recovered using the same techniques as DriveStation devices.

How to Recover Data from Buffalo External Hard Drive

Let’s start by walking you through the process of Buffalo external hard drive data recovery on Windows 10/11 using data recovery software called Disk Drill Data Recovery (you can also follow the steps below on macOS).

Disk Drill is one of the best data recovery apps that you can use to recover lost data from your Buffalo external hard drive because it supports all commonly used file systems (FAT16 / FAT32, exFAT, NTFS / NTFS5, HFS / HFS+, APFS, ReFS, ext2 / ext3 / ext4) and features a straightforward data recovery process that consists of only a few simple steps:

  1. Download and install Disk Drill on your system drive.

How to Restore Deleted Data from a Buffalo NAS Drive

In this section, we will explain how to recover files from Buffalo data storage DriveStation, TeraStation, and LinkStation NAS drives using two methods: one direct and one indirect.

Again, we will demonstrate each method using Disk Drill because the tool supports not only RAID0, RAID1, RAID5, RAID6, and RAID10 arrays but also RAW recovery, making it perfect for NAS and external hard drive data recovery.

Recover Data Directly from Buffalo NAS

To recover data directly from Buffalo NAS:

  1. Connect the Buffalo NAS storage to your PC via USB.
  2. Download, install, and launch Disk Drill.
  3. Select the NAS and click Search for lost data.
  4. Add each missing file to the recovery queue.
  5. Click the Recover button and select a suitable destination.

Retrieve Files From NAS Hard Drives

To retrieve files from NAS hard drives:

  1. Unmount all Buffalo NAS hard drives and connect them to your PC.
  2. Download, install, and launch Disk Drill.
  3. Select your first drive and click Search for lost data.
  4. Select as many missing files as you can find.
  5. Click the Recover button and select a suitable destination.
  6. Repeat steps 1-5 for the remaining drives.



Buffalo external hard drives and NAS data storage devices are favored by many Windows 10/11 users. Because no storage device is 100% reliable (and because users make mistakes), it’s inevitable for Buffalo external hard drive- and NAS-related data loss to occur and affect a small but still significant percentage of unfortunate people. The good news is, it’s usually possible to recover files from Buffalo data storage devices using the techniques described in this article.
