NAS data recovery refers to the process of retrieving lost, inaccessible, or deleted data from Network Attached Storage (NAS) devices. Data loss can occur on NAS systems due to various reasons such as hardware failures, software issues, accidental deletions, or logical errors.

  • NAS hardware of hard drive failure?

  • NAS system no longer identified by the sysstem?

  • Incorrectly configured RAID setups, disk failures, or RAID controller problems?

  • Failed or incomplete updates to NAS firmware or software causing data corruption or loss?

  • Mistakenly formatting the NAS drives or volumes erasing all the data stored on them?

  • Malfunctioning or failed components such as missing hard drives or incorrect RAID disk arrangement? 

  • NAS system has been dropped or has sustained physical impact?

If your files have disappeared from your Synology NAS system due to damage to the hard drives or any other reason, then Wildfire Data Recovery can help you rescue your precious files. We work closely with small business clients and corporate clients.

NAS data recovery is crucial for businesses and individuals who rely on NAS devices to store and manage their critical data.

General overview of Synology NAS products:

"With Synology NAS, you can store and share files centrally, back up data from multiple devices, and stream media content to various devices."

The company has two major product lines: DiskStation and RackStation. DiskStation models are primarily designed for households and up to medium-sized offices. Such devices have pedestal or tower-like enclosures and may contain from one to as many as 12 bays.


RackStation models prevail in big enterprises. These are rack-mounted industrial solutions that typically have much more capacity and computing power than their counterparts. The drive bays of both device types can hold hard disk drives or solid state drives. The company has also started offering all-Flash rack-mounted arrays with the FlashStation series.

Some devices within each line can be paired with physical expansion units for additional storage space. The storages themselves don’t provide NAS functions, they have to be connected to the corresponding DiskStation, RackStation or FlashStation appliances, depending on the first letter in their names.

What software and file-systems do Synology NAS systems use:

All Synology NAS appliances run a proprietary Linux-based operating system called DiskStation Manager or simply DSM. It has an intuitive web interface and covers most vital NAS functions, such as file sharing, data management and protection, backups, cloud services, virtualization and others.

  • Depending on the model, Ext4 and the newer Btrfs file system of Linux can be used for creating Synology NAS volumes. If both are supported by the device, users can choose either of these file systems, depending on their preferences.

  • Furthermore, all Synology NAS boxes support the 256-bit AES data encryption. When enabled for a shared folder, the data within it is stored in an encrypted format with a set of encryption keys. This is a critical bit of information when performing data recovery on Synology systems that has failed. Accessing encrypted files can be a big problem. 

How is data organised on a Synology NAS:

Synology NAS units support multiple RAID options that may vary depending on the model. Some of them may not be configured as RAID and thus lack redundancy. The possible variants include:

  • RAID 0 may also be used in low-end NAS boxes. It combines two or more drives and offers higher access speeds than individual drives. Yet, the data is not protected against disk failures.

  • RAID 1 is applied on two-drive NAS units and provides a full backup in case of breakdown of a single drive, since the drives are identical clones of each other.

  • RAID 5 requires minimum 3 drives, offers faster access to the data and allows the system to keep operating if one of them fails. This is the most popular configuration, especially in the business environment.

  • RAID 6 needs at least 4 drives, accelerates access to the data, and makes it possible to recover the system even when two drives fail at a time. This is a very reliable, yet, not particularly cost-efficient configuration.

"You may only get one shot at recovering your precious choose wisely."


NAS (Network Attached Storage) systems can be built on various RAID (Redundant Array of Independent Disks) configurations to enhance data storage, reliability, and performance. RAID is a technology that combines multiple physical drives into a single logical unit, providing various levels of data redundancy and improved access speeds. A crucial step in RAID array recovery is knowing which RAID level are you using. The most common RAID configurations include:

RAID storage systems either use a software or a hardware controller to ensure the RAID arrays work together. A common reason behind RAID data loss is a corrupt or failing RAID controller. One telltale sign of this is data loss, even though all individual drives are in full working order.

Synology Hybrid RAID:

(SHR) is the specific technology of the brand that allows creating RAID from drives of different capacities and add new ones to it anytime. This is basically achieved by establishing several RAID layouts over the disk set. The first RAID is created from the “portions” of the drives whose sizes equal to the capacity of the smallest drive. The remaining “tails” of the drives with larger capacities are organized in another RAID. After that, both sets are spanned together to constitute a single storage unit. The inner mechanism relies on the combination of Linux mdadm and LVM. Yet, in general, when the drives of the same sizes are used in the array, the technology works the same way as the traditional mdadm RAID 5 (or RAID 6).

Advantages and shortcomings of a Hybrid RAID System:

Synology Hybrid RAID can boast a number of the key strengths in comparison to classical RAID which is also available as a configuration option for most Synology NAS models:

  • hard drives of different manufacturers, speed and capacities can be mixed in one SHR;

  • SHR made up of dissimilar capacity drives provides a much bigger amount of usable storage space when compared to RAID – only one largest drive is “lost” for redundancy;

  • even so, Synology RAID guarantees protection against one failed drive and the subsequent data loss (with SHR 2 – even two disk failures);

  • new drives can be added to SHR anytime – no preliminary calculations are required;

However, SHR can be characterized by a slightly lower speed. Also, a rather complicated structure may become a hindrance to retrieving critical files in case of data loss.

Our Wildfire Data Recovery, NAS file recovery services come with a documented 95% success rate. Like all electronic devices with built in complexity, NAS systems have limitations to what can be recovered. This of course depends on the issue and the complexity of the problem. 

While we can help in many situations, unfortunately data recovery isn't always possible from NAS devices. Below is a quick summary of the most common NAS data loss presentation we recieve here at WDR.


  • Unintentionally deleted from the NAS device

  • File System Corruption

  • Physical Impact

  • Disk Failure in RAID Configurations

  • Partition Table Issues

  • Damaged Hard Drive Issues

  • File System Errors

  • Accidental Formatting

  • User Faults

  • Deleted or damaged partitions on NAS

  • Corruption in the NAS firmware

  • Inaccessible or Unmountable Drives

  • Power Outages


  • Extensive physical damage to the NAS device, such as fire, flood, or extreme impact

  • Severe Data Overwritting

  • Encrypted Data Without Recovery Key

  • Bit Rot or Data Degradation

  • Intentional Data Removal (inc. DoD data deletion)

It's important to note that each data loss scenario is unique, and the success of data recovery depends on several factors such as the severity of the damage, the expertise of the data recovery specialists, and the available resources and technologies.

"It is as easy as 1, 2, 3. Our hard drive data recovery process is customised for every client."



Once we process and diagnose our client's device(s) we complete a comprehensive diagnostic report. It marks on the total costs (inc. projected costs) of the recovery, the chance of success, the issue with the hard drive and why it requires data recovery services and finally the expected date of completion. We offer our customers a comprehensive diagnostic report free of charge with our standard service, to find the root of the failure and allow our engineers to find the right path to recovery.



Following the completion of our comprehensive recovery report, we complete our diagnostic and consultation services with our clients and provide a projected success rate for their particular device and failure (these success rates are based on thousands of recoveries). Once the diagnostics are completed buy our experienced data recovery engineers, and the data recovery options are clear, we provide a firm no-obligation price quote. This quote can always be rejected by our clients and they can take their device and shop around.



Once our clients provide us with the green light and approve the quote and the comprehensive report, our engineers conduct the invasive hard drive repairs and if necessary, use custom-designed, in-house, tools to recreate file systems and partition table information our clients need to progress to the next level of hard drive data recovery. This step can take a number of days, to a number of weeks depending on the complexiety of the hard drive failure. For example, a LEVEL 1 Logic Hard Drive Data Recovery may take 2-5 days, while a LEVEL 4 Complex Mechanical Hard Drive Failure can take up to 4 weeks or longer.
