Synology Data Recovery

If your Synology has one or more failed hard drives, a failed RAID, or a firmware update crashed the drive, and you’ve already tried to recover the data yourself, without success, PLEASE STOP NOW.

DIY data recovery and the lack of expertise of other providers causes more complete data loss situations than any other failures we encounter. If you are serious about your data and it is important to you, please contact us so that one of our engineers can advise you. It’s critical that further data damage is prevented.

Getting Your Data Back

In the first instance, contact us. On our website there is plenty of information, from delivery and turnaround to what happens if you’re outside of the UK, along with a list of FAQs that will help put your mind at ease.

Our engineers know and understand storage. They recover data from failed drives, RAID crashes, failed RAID rebuilds and firmware updates. If a disk crash or corrupt system means you cannot access the device, they will repair it and retrieve the data.

RAID Recovery Experts

We have industry-leading RAID recovery skills, and are able to restore your system from any failure. Even if you have already been told your data cannot be recovered, we often manage a successful recovery where others have failed. Please contact us; there is nothing wrong with a second opinion.

As well as having knowledge of all file systems and operating systems, our engineers recover failed RAIDs of all levels, including the common RAID 0, RAID 1, RAID 5 and RAID 6.

They have experience of all Synology CubeStation, DiskStation and RackStation devices, with any configuration, with any damage such as power surges, failed drives, failed RAID rebuild – or maybe you cannot access the device or a shared volume. If someone accidentally deleted data, that can also usually be retrieved.

Recovering Synology NAS From Failure

• Failed hard disk drive – blinking orange LED light.
  Almost always recoverable – even if more than one drive fails.
• Critical system error – flashing blue LED light.
  This could be caused by almost any component error, or if the RAID
  parameters have been damaged or changed.
• Power surge or failure can cause a hard disk crash.
  Power spikes can damage the Synology device itself, which will result in complete loss of access to the data.
• RAID rebuild failed. If you have swapped out a hard drive and a RAID rebuild was started but the Synology is hanging, it may be that the rebuild is corrupting the data. If you contact us, we will advise you what to do.
• Volume auto rebuild failed. This can happen if the hot spare fails, or if it is prevented from completing for any other reason. Even the tiniest amount of media (platter) damage can cause a disk to fail.
• System volume is in degraded mode. A degraded volume is a RAID array that has redundancy, such as RAID 5. When a drive fails and is replaced with a healthy drive, the RAID will run in degraded mode until the rebuild completes.
• Device will not boot. Caused by any number of problems, such as a failed software upgrade, corrupted system or other electrical or mechanical failure of any component.
• Cannot access the device or the share. This might be a software configuration error, or the logical or physical failure of any component within the Synology.
• Firmware update failed or firmware software upgrade failed
