At Cardiff Data Recovery, we are Wales’s leading specialists in data recovery from NAS devices, offering expert services for failed 2-disk RAID 0 systems. If your NAS won’t boot or displays drive errors, it could indicate a firmware corruption, RAID configuration fault, or hardware failure. We understand how critical your NAS data is and offer reliable, forensic-level recovery to restore what matters most.
With over 25 years’ experience, our engineers have successfully recovered data from thousands of failed RAID 0 configurations — even in cases where other providers have declared the data unrecoverable.
⚠️ Why RAID 0 NAS Systems Are High-Risk
RAID 0 (also known as striping) is a performance-based array where data is split evenly across two disks. However, this configuration offers no redundancy. If just one drive fails, the entire dataset becomes inaccessible.
In a NAS environment, common reasons for RAID 0 failures include:
- NAS firmware update failure or corruption
- Failed NAS motherboard or backplane
- Disk synchronisation issues
- Accidental RAID reinitialisation
- Drive read/write errors or sector-level degradation
- Physical impact or power surge
As there is no parity or mirroring, RAID 0 failures require immediate professional intervention to maximise recovery potential.
🛠️ How We Recover Data from a Failed NAS RAID 0 – Step-by-Step
1. Initial Device Inspection & Drive Extraction
- We begin by safely powering down and disassembling the NAS unit
- Drives are removed and labelled in correct order to preserve original array sequence
- We document the make, model, and firmware version of the NAS for reference
2. Sector-Level Imaging of Both Drives
- Each disk is imaged using forensic hardware with write-block protection
- We use advanced tools to handle slow or bad sectors using multi-pass imaging and ECC correction
Recovery is performed from images only — never the original drives — ensuring data integrity.
3. Virtual Reconstruction of RAID 0 Configuration
- We analyse stripe size, disk order, and RAID metadata
- A virtual RAID 0 array is created from the disk images
- We simulate the original RAID layout without relying on the failed NAS firmware
This allows full access to the logical volume without modifying original data.
4. File System Repair and Data Extraction
- The original file system (e.g., EXT4, XFS, BTRFS, or NTFS) is repaired or reconstructed
- If the file system is heavily damaged, we use raw data carving to extract files by format signature
- Files are copied and validated for integrity on a secure output device
