Buffalo NAS Disk Repair


I have been using a Buffalo Ministation as an external hard drive, using the SATA hard drive with around 250gb of memory. I plugged it in this week, and it suddenly showed an error, where the computer stated that the hard disk might have a problem, or be unstable, and could crash. It warned me that I needed to make a backup. I pressed OK, and my Ministation started to back up, then rebooted. After the reboot, it failed, and now will not boot up any more. I removed the disk, and plugged it directly into the computer. I can see data in BIOS, but not in the operating system. I have tried to build a new operating system, but when I am installing the program (windows XP), I can see partitions, but I can’t amend them, delete them or access the data on them, as the machine just aborts the operation. Windows 7 will not detect the drive at all. The drive appears to be reporting a SMART failure when I put it into BIOS, which seems to suggest that I won’t be able to get any of my data back at all. This is a serious problem, and I really need help.


I am using a Buffalo Drivestation Ultra, which as a 4TB drive. As soon as I received the external hard drive, I transferred a large number of files on to it. I had to do this as my computer was running out of space on its own hard drive, so I needed somewhere to store it. I turned the device off, and thought no more about it. However, a week afterwards, I plugged in the drive in order to view some of the files, and found nothing. There was not even a space for the files, no folders, nothing. There were not even the files that are preloaded by Buffalo, and are used in case the drive fails, or something. I contacted Buffalo tech support, but they are not responding, and don’t seem interested in this problem. They offered a few simple steps such as rebooting computer etc but nothing to sort out the issue for me. I really need to find this data.

Buffalo NAS Disk Repair

Buffalo have produced a large variety of network storage devices for use with individual computers as well as network setups and Apple Macs.

Available with a variety of large volume disk drives – some including more than one disk drive – the Buffalo range including the Linkstation brand offer the user reasonably reliable hardware for use in storage large volumes of data such as audio, video and photo. They can also be used to copy partitioned elements of your internal hard disk drive directly from your computer.

A common problem with a number of these models is that the computer to which they are attached can suddenly fail to recognize the drive and throw the external drive into EM Mode (Emergency Mode).

When this happens the external drive has effectively died and will not allow any information to be saved to or accessed from the networked storage device.

For users contacting Buffalo directly they can, – and often are offered the opportunity to reformat the drives with the computer’s onboard utility but this simply means losing all of the information contained on the drive or drives.

As perhaps useful a utility as this might be it does not help accommodate the user when it comes to trying to save their already stored information and data.

A commonly listed reason for such problems occurring is power outages or surges that send the drives into EM Mode (Emergency Mode).

Emergency Mode although sounding helpful can cause more problems than it solves and as we have already mentioned can lead to a general reformat resulting in the loss of all data and information stored on the drives.

A sure fire way of diagnosing a problem relating to the disk drives of an external Buffalo NAS setup is a set of blinking LEDs which, when they blink six times indicate a faulty disk. Even with these lights flashing the user or network administrator can access the drive via the IP (Internet Protocol) address but even though the drive is visible it is not accessible.

As with a great many network storage setups it has been suggested on the Internet that the removal of these drives from the unit can help if they are replaced with new drives but in doing so one is reducing the chances of saving the information and data on those drives the NAS registers as not functioning.

Should you encounter any of the aforementioned problems it is advisable to contact www.brighton-datarecovery.co.uk before consigning the drives to the bin or indeed attempting to reformat which as we have already stated will result in an almost definite loss of all information contained therein.
