What causes NAS failure?

Although a NAS device is considered reliable, sometimes it can fail. The main parts of a NAS are a controller, several hard drives, a file system and a network interface that helps for data transferring over the local network.

General causes of a NAS failure:

  • mechanical damage of some NAS component,
  • file system failure,
  • network interface failure.

If your NAS failed, do not try to reconfigure it. This may cause the RAID array to initialize. Often, when the reconfiguration ends, you lose all data.

In most of the above cases of NAS failure you can try to recover NAS data DIY with ReclaiMe File Recovery software.

If you have just deleted data from the NAS device, you do not need to pull the disks out. Just install ReclaiMe NAS Recovery software on your PC, select your NAS, connect to it by entering the login and password, start scanning the NAS volume and then check the result of the file recovery in the Preview window. You can find more information on how to recover deleted files from a NAS drive on this page.

The procedure is more complicated in case of more serious logical malfunction:

  1. Remove all disks from your NAS and connect them to the PC motherboard via SATA ports. If there are not enough SATA ports, use USB-to-SATA adapters.
  2. Download and run ReclaiMe File Recovery software.
  3. Choose your NAS volume and start the scan.
  4. When the scan is completed, check the recovered files in the Preview window.

More information about how to recover data from a NAS device read on this page.

If ReclaiMe File Recovery software does not display the NAS volume, most likely the RAID array configuration was destroyed and first you need to recover original RAID array parameters with ReclaiMe Free RAID Recovery software. More about RAID recovery you can find on this page.

If you can't recover data within the DIY approach or there are more failed disks than the redundancy allows, contact a data recovery service like SalvageData.
