Buffalo Data Recovery


I am in urgent need to help! I have a Buffalo external hard drive which has a lot of important information on, including archives and folders containing passwords and other data that I have to have. The problem started when my old power cable suddenly stopped working. I bought another power cable (emergency buy) and thought that as it was the same spec, it would all be ok. However, when I plugged it into the machine, there was a sudden ‘pop’, and the drive could not be found on my PC. I have discovered some data not available inside my PC, and so the Buffalo is the only source of some essential files. I know that some of these drives are built to withstand excessive amounts of voltage, and hopefully I can find a way to tell if mine has this capacity. However, I don’t know what I should be doing in order to recover the information and also to save the Buffalo drive, which I really need. I would be very grateful for your expert data recovery opinion.


Using a Buffalo Ministation last week, I suddenly found myself with a bit of a problem. I wanted to resize my partition inside my laptop (not the drive itself), but found afterwards that my external hard drive (the Ministation) has suddenly stopped working. I had left it plugged into the computer while I was doing the resizing, but it should not have affected the external drive. What I do know is that the Buffalo is still showing up, but only as a RAW drive. I have tried to find recovery data which found the files, and was saving them, when I suddenly realised it was the wrong recovery option (rather than RAW), and so I had no choice but to cancel. Now, not even the recovery programs can see the HDD. None of the programs, and none of the PC systems I use can see the drive. It is still running when plugged in, but the drives have become invisible. I have not formatted anything, but I realise that the recovery program may have done so before trying to save the files. I know it is an enormous mess which I have made worse, but you help me recover my files?

Buffalo Data Recovery

The Buffalo name is often thought of as being one of the world’s biggest providers of server technology, including EXTERNAL HARD DRIVES, NAS DRIVES and RAID SYSTEMS. In fact, Buffalo was one of the first companies to offer smaller versions of this technology, more suitable for usage in private homes and smaller office settings. Buffalo has been providing infrastructure technology throughout the world since 1975, and works with top companies, including Intel, Broadcom and Microsoft.

Buffalo has a good name among data recovery specialists, and is considered a reliable way to store data, particularly because of its high level of redundancy, as is common with servers that operate with RAID arrays. Despite the reliability and positive reputation of Buffalo, failures are possible, and occur for simple reasons, such as power surges, drive failures and errors on the part of the user.

Buffalo TetraStations

A Buffalo TetraStation is a terabyte Network Attached Storage (NAS) device that is used for a number of reasons including its powerful storage capabilities, and innovative server and multimedia capabilities and features. A TetraStation is an integration of advanced fault tolerant data solutions and very strong file security. It’s also touted as being a very cost-effective way for users to have a simple, easy-to-use and relatively inexpensive server, without sacrificing performance or proficiencies.

Reasons Buffalo NAS Devices Commonly Fail:

  • Failures of the firmware or hardware
  • User error that can lead to reconfiguration
  • A failure of the hard disk
  • A power problem or disconnection that occurs during the update of the firmware

The Process of Recovering Data from a Buffalo Device
As with many hard drive devices, it can be a very complicated process to recover data from a Buffalo device. Most data recovery services prefer to do the work on-site, because the proper tools and environment are needed to ensure a safe and efficient recovery process. Often, when working to recover data from a Buffalo device, a process of de-striping is utilized. De-striping refers to the steps used to take the data from an array format, and place it into a single file.

What to Do if Your Buffalo Device Fails

Since Buffalo data storage devices are frequently used in a business setting, if there is a failure experienced, the best course of action is to work to remedy the problem and recover all data as quickly and harmlessly as possible. All too often, individuals will attempt to troubleshoot problems on their own, but the only way to successfully recover data in most circumstances is to contact a data recovery service.

In many circumstances, when an individual attempts to recover data or fix a problem with a Buffalo device on their own, further damage can be done that will render the data completely irretrievable.

Common error codes witnessed by the user during a failure of a Buffalo device include E11 and E12, both of which are related to overheating, and E22 errors, which are often because of problems with the RAID controller.

While it can be helpful to note an error code that occurred before a failure of a Buffalo device, it’s not necessary to the recovery process, so it’s not advisable to restart the system to find out the error code. The best course of action is the keep the system completely turned off until you can contact an appropriate data recovery service, who will perform a full diagnostic examination of the problems occurring in the device. We can diagnose your device within 24 hours to determine the level of recovery.
