What to do if NAS fails?

So, one not very fine day, your NAS device stopped showing signs of life - the lights are off and nothing works. Or your computer cannot access the NAS device even though the lights and power are on. Or suddenly the NAS device interface shows you error messages.

What to do?

First you need to figure out what is causing the breakdown. May be:

  • failure of the NAS device itself (a controller, a power cable, a box etc.),
  • mechanical disk failures,
  • filesystem errors,
  • network interface failure.

If the NAS is physically damaged and still under warranty, you can contact the manufacturing company or NAS repair service. They will determine what happened and probably replace or repair damaged parts. But don't forget to remove the disks from your NAS before taking it to a repair shop, because often after the repair NAS does not recognize its original disks and therefore start to initialize them, which will result in data loss. That’s why you should create disk image files of the original disks.

If the problem is related to hard drives and there are more damaged drives than the redundancy allows, you need to send them to a trusted data recovery service like SalvageData.

If only one disk is damaged, for example in a RAID5, exclude it from the recovery process and try to restore your data using software.

If file system is logically damaged, you can try to recover data DIY using ReclaiMe File Recovery.

So, the procedure is as follows:

  1. Pull all the disks out of the NAS and connect them to the motherboard of the Windows PC.
  2. Download and run ReclaiMe File Recovery software.
  3. Select the NAS volume in the device list and click the Start button.
  4. After the scan is complete, check the result of data recovery. Select some image files and check them in the Preview window.
  5. If your files are OK, activate the software and save the data to another disk.

If you cannot find the NAS volume in ReclaiMe File Recovery software, the array configuration is most likely corrupted. In this case, you first need to recover RAID array parameters using ReclaiMe Free RAID Recovery software. Download and run ReclaiMe Free RAID Recovery software, select all NAS drives and click the Start button according to your RAID level (more detailed information about RAID recovery read on this page). When the RAID configuration is being recovered, and if you have already installed ReclaiMe File Recovery, the software will open in RAID recovery mode. If you do not have ReclaiMe File Recovery software, you will be be prompted to install it to start the file recovery process.
