Our D-Link NAS Data Recovery Services

We provide comprehensive data recovery solutions for every type of D-Link device and failure scenario.

• D-Link NAS Multi-Drive Recovery: Specialist recovery from multi-bay D-Link NAS units (DNS-340L, DNS-320L, etc.), focusing on RAID reconstruction and proprietary file systems.

• Single-Drive NAS Recovery: Data extraction from single-bay D-Link devices where the drive itself has failed logically or physically.

• Logical Volume Reconstruction: Recovery from drives where the NAS’s proprietary volume manager or file system (often based on Linux XFS/EXT4) has become corrupted.

• Physical Drive Recovery: Recovery from individual hard drives that have suffered internal physical damage after removal from the D-Link NAS enclosure.

• Failed RAID Rebuild & Synchronisation: Complex data reconstruction from D-Link NAS systems where a RAID rebuild has failed or caused further data loss.

Top 20 D-Link NAS Drive Faults We Recover From

Our engineers successfully recover data from a vast range of D-Link NAS-specific and general storage faults. Here are twenty of the most common, with a detailed explanation of the fault and our professional recovery process.

1. RAID Volume Degradation & Collapse

   • Fault Details: The failure of one or more drives in a D-Link NAS RAID (e.g., RAID 1, RAID 5) causes the volume to degrade and become inaccessible, especially if a second drive fails during a rebuild.

   • Recovery Process: We create full sector-by-sector images of each member drive. Using specialised software, we analyse the RAID parameters (stripe size, order, parity, and rotation) to virtually reconstruct the array, bypassing the faulty NAS hardware.

2. Proprietary NAS OS/Controller Failure

   • Fault Details: The D-Link NAS hardware controller or its embedded operating system fails due to a firmware corruption, power surge, or failed update, rendering the unit unresponsive even with healthy drives.

   • Recovery Process: We remove the hard drives from the NAS enclosure and connect them directly to our recovery hardware. We then analyse the data layout on the disks to virtually reassemble the RAID and file system without the original D-Link controller.

3. Linux-based File System Corruption (XFS/EXT4)

   • Fault Details: D-Link NAS devices typically use Linux file systems like XFS or EXT4. The journal or superblock can become corrupted due to power loss or bad sectors, making the data unreadable.

   • Recovery Process: Our engineers use Linux-based recovery tools to repair the corrupt journal and superblock. If the primary superblock is damaged, we use backup copies located at various points on the drive to restore access to the file system.

4. Accidental Deletion or Formatting on NAS

   • Fault Details: Files or entire shares are deleted from the network volume, or the volume is accidentally reformatted through the NAS management interface.

   • Recovery Process: We perform a deep, raw scan of the reconstructed RAID volume, searching for residual file system structures and file signatures to rebuild the directory and recover the lost data.

5. Multiple Concurrent Drive Failures

   • Fault Details: More than one drive in a D-Link NAS array fails simultaneously or in quick succession, exceeding the redundancy of the RAID level and causing total data loss.

   • Recovery Process: We image all drives, including the failed ones. Using advanced techniques, we combine the best data segments from each drive to create a composite image of the degraded array, from which data is then extracted.

6. Failed RAID Rebuild Process

   • Fault Details: The NAS automatically or manually initiates a rebuild onto a new drive, but the process fails or corrupts the volume due to an underlying issue on a remaining “healthy” drive.

   • Recovery Process: We analyse the drives to determine the state of the array before the failed rebuild. We then use this pre-failure state to reconstruct the data, effectively rolling back the damaging rebuild process.

7. Bad Sectors on Multiple Array Drives

   • Fault Details: Media degradation causes unreadable sectors to develop on more than one drive in the array, preventing the RAID from functioning correctly.

   • Recovery Process: We use imaging hardware with advanced error correction to read as much data as possible from each drive. The redundant nature of RAID is then used to fill in the gaps from unreadable sectors.

8. Power Supply Unit (PSU) Failure

   • Fault Details: A faulty NAS power supply causes inconsistent power to the drives, leading to PCB damage, firmware corruption, or physical head crashes.

   • Recovery Process: We diagnose and address the damage on a per-drive basis, which may involve PCB repair, firmware recovery, or physical component replacement before the array can be reconstructed.

9. Firmware Upgrade Corruption

   • Fault Details: An interrupted or corrupted firmware update bricks the NAS device, making it unable to boot and access the drives.

   • Recovery Process: The drives are removed from the bricked unit. As the data is typically stored on the drives independently of the NAS OS, we can access it directly by virtualising the RAID configuration on our recovery systems.

10. Volume Configuration Database Loss

    • Fault Details: The NAS’s internal database that stores the RAID configuration (disk order, type, etc.) is lost or corrupted.

    • Recovery Process: We perform a manual analysis of the drives to determine the correct RAID parameters by looking for repeating patterns, parity data, and file system signatures.

11. Virus & Ransomware Infection on Network Share

    • Fault Details: Malware encrypts or corrupts files stored on the NAS network shares.

    • Recovery Process: We create a forensic image of the entire volume. We then use data carving techniques to recover pre-infection file versions and, for ransomware, explore known decryption methods for the specific strain.

12. Water & Liquid Damage to NAS Unit

    • Fault Details: Liquid causes short circuits on the NAS motherboard and drive PCBs.

    • Recovery Process: The drives are removed, cleaned, and have any damaged components replaced on their PCBs. They are then imaged individually for the array reconstruction process.

13. Overheating Damage in NAS Enclosure

    • Fault Details: Inadequate cooling in a multi-drive NAS leads to chronic overheating, accelerating drive wear and causing read/write errors and premature failure.

    • Recovery Process: Drives are stabilised and cooled during the imaging process. We create clones of each drive to work with, preventing further stress on the degraded originals.

14. Physical Impact & Drop Damage

    • Fault Details: The NAS unit is dropped or struck, causing potential physical damage to multiple drives inside (e.g., head crashes, platter damage).

    • Recovery Process: Each drive is assessed individually. Physical repairs (head swaps, etc.) are performed as necessary on each drive before the data from all members is synchronised for array reconstruction.

15. Partition Table Corruption on NAS Drives

    • Fault Details: The partition table on one or more drives within the array is damaged, confusing the NAS controller.

    • Recovery Process: We manually repair or recreate the partition tables on the individual drive images, ensuring the array virtualisation software can correctly interpret the data segments.

16. Unsupported File System Modifications

    • Fault Details: A user attempts to modify or repair the drives from the NAS using a standard PC OS, which can damage the proprietary volume structure.

    • Recovery Process: We ignore the incorrect modifications made by the PC OS and work with the raw underlying data structure to reconstruct the original NAS volume.

17. Wear and Tear (Mechanical Failure)

    • Fault Details: General ageing of mechanical components in multiple drives leads to coincidental failures within the NAS array.

    • Recovery Process: The specific failing component in each drive is addressed. We then use the most current data from each drive to piece together the complete dataset.

18. S.M.A.R.T. Errors & Predicted Failure

    • Fault Details: The NAS management system alerts you to imminent drive failure based on S.M.A.R.T. data, but the drive fails before it can be replaced.

    • Recovery Process: We immediately create sector-by-sector clones of all drives in the array, prioritising the failing one, to secure the data before attempting reconstruction.

19. Controller Board Failure on Individual Drive

    • Fault Details: The PCB on one of the hard drives inside the NAS fails.

    • Recovery Process: We diagnose the fault and perform a PCB swap, transferring the unique adaptive data from the patient PCB to a compatible donor PCB to allow imaging of that specific drive.

20. Data Pool Corruption on D-Link NAS

    • Fault Details: The logical data pool, a layer of abstraction above the physical RAID, becomes corrupted, making shares inaccessible even though the underlying RAID is technically healthy.

    • Recovery Process: We analyse the pool metadata to understand the corruption and then use specialised tools to extract files and folders directly from the underlying block device, bypassing the corrupted pool structure.
