Synology NAS Recovery

Synology has been a highly respected player in the NAS market for a number of years now. Their devices are intuitive to use and reliable. However, occasionally due to disk failure, file system corruption or a failed RAID array, data recovery will be required.

We can recover data from most Synology NAS devices. We have experience in recovering data from several Synology devices, such as models:

Typical scenarios that necessitate data recovery from Synology NAS devices include:

Frequently asked questions about Synology NAS data recovery

I suspect that I have a failed disk in my Synology DS413 (RAID 5). What should I do?

The status light should be blinking yellow and the failed drive number will be indicated by the HDD LED lights on the front panel of your unit. Log into the administration control panel of your NAS via it’s web interface to confirm whether your unit is reporting the disk as degraded, defective or crashed.

  1. Go to Main Menu.

  2. Storage Manager.

  3. Volume.

  4. Click on the “Beep Off” button.

  5. Here you should see details about the status of your disks.

(These steps might differ, depending on which version of Disk Station Manager your NAS is using)

In certain circumstances, Synology will not report any problems with your disks under the “Beep Off” section. Thankfully, however, Synology provides us with a second technique to verify disks.

  1. Go to the Main Menu.

  2. Click on System Information.

  3. Select the last tab labelled “Log” to see what status is being reported.

  4. Carefully scroll through this log looking for red Xs accompanied by error messages (such as “Volume was degraded, please repair it”).

  5. If you spot these errors, it is time to replace the faulty disk. If you do not replace the disk at this stage, your NAS no longer has any redundancy and your risk of data loss is increased.
