Unexpected hardware failure can turn a normal workday into a crisis. This is especially true for businesses that rely heavily on centralized data storage. That’s exactly what happened to one of our clients who contacted us in urgent need of WD NAS data recovery assistance. Their WD ShareSpace NAS suddenly stopped working, and years of project files, financial documents, and internal resources became completely inaccessible.
The issue stemmed from a power supply failure, but the real challenge was the device’s configuration. The client had used RAID 0, a performance-oriented setup that unfortunately offers zero redundancy. With no external backups in place and the business at risk of operational delays, the clock was ticking a textbook case requiring urgent RAID 0 data recovery.
This case is a prime example of how proper handling, technical expertise, and advanced tools can turn a catastrophic failure into a full recovery success.
Understanding the WD ShareSpace Device
The Western Digital ShareSpace is a four-bay network-attached storage (NAS) system designed for businesses and power users. It supports both RAID 0 and RAID 5, has Gigabit Ethernet connectivity, and includes USB 2.0 ports for external expansion.
In this case, the unit was configured in RAID 0, which stripes data across multiple disks to increase performance. However, RAID 0 does not provide any protection if even one drive fails or becomes corrupted. The system had been used to store shared documents, accounting files, archived projects, and other critical company data.
When the power supply failed, the entire NAS shut down suddenly, and the user could no longer access any files via the network interface. Restart attempts were unsuccessful.
Initial Evaluation and Problem Identification
When the WD ShareSpace arrived at our lab, our team of engineers began with a risk-free diagnostic evaluation. The NAS enclosure was completely unresponsive, confirming a failure in the internal power delivery system.
However, the hard drives themselves were not damaged physically. We carefully removed all four drives and examined their SMART data, spin-up behavior, and read access under controlled lab conditions. It was evident that the abrupt power loss caused a file system corruption across the striped RAID 0 volume.
The RAID metadata appeared inconsistent, which meant the array could not be automatically mounted without risking further damage. Fortunately, none of the drives had bad sectors, mechanical damage, or media-level defects. That gave us a strong foundation to move forward.
The Recovery Process: Step-by-Step Breakdown
Step 1: Drive Imaging
To prevent any further risk to the original drives, each one was immediately cloned using our sector-level imaging hardware. This process captures the full contents of each disk byte-for-byte. Imaging ensures we work only on safe copies and preserves the original condition of the source media.
Step 2: RAID 0 Reconstruction
RAID 0 stripes data across multiple drives in sequential blocks. Without any built-in redundancy, identifying the correct drive order and stripe size is crucial. A single mismatch can result in corrupt output or incomplete files.
Using proprietary software, our RAID team analyzed data patterns, filesystem structures, and disk headers to reverse-engineer the original configuration. After multiple test builds and validations, we successfully reconstructed the virtual RAID 0 array and were able to mount it in a read-only environment.
Step 3: File System Repair and Logical Recovery
Although the RAID structure was restored, the file system had sustained logical damage. Several index tables and directory entries were broken, and many files had incorrect headers or missing references.
Our engineers used advanced data carving techniques and manual repair utilities to reconstruct directory structures, restore folder hierarchies, and recover usable file segments. This step required significant attention to detail and over 20 hours of labor-intensive analysis.
Step 4: Data Validation and Transfer
Once recovery was complete, we transferred the recovered files to a new encrypted external drive. The client participated in a remote verification session, during which they confirmed that their accounting data, project folders, and business-critical documents were fully functional and accessible.

Recovery Outcome
The full recovery process took approximately 40 hours, from evaluation to final delivery. Our team successfully recovered over 99 percent of the requested data. This included intact Hyper-V machine files, PDF archives, accounting spreadsheets, and client deliverables that were actively used by the team.
The client expressed immense relief and appreciation for the speed, clarity, and professionalism of the process. Without a backup in place, this recovery saved them from what could have been weeks of lost productivity and revenue.
