Iomega LinkStation NAS devices are commonly used for personal and business data storage, including photos, work documents, and backups. However, when a RAID 5 NAS experiences a power surge, it can result in RAID corruption, file system failure, and complete data inaccessibility.
This case study details how we successfully recovered critical work documents and photographs for a Guildford-based professional from an Iomega NAS server with a four-disk RAID 5 configuration, after a power surge rendered the array unreadable.
As Guildford Data Recovery, Surrey’s oldest and best data recovery company, we have 25 years of experience using RAID reconstruction, NAS file system repair, and forensic data extraction techniques to restore lost data securely and confidentially.
Iomega LinkStation RAID 5 Fails After Power Surge
A Guildford-based professional contacted us after their Iomega LinkStation NAS stopped functioning, with the following issues:
- After a power surge, all RAID 5 drives were reported as corrupt.
- Attempts to rebuild the RAID in a new array resulted in “Specify Filesystem Type” errors.
- The computer would not allow access to any stored data.
- The NAS contained crucial work documents and irreplaceable photographs.
Since RAID 5 is highly dependent on parity and metadata, improper rebuild attempts can cause irreversible data loss, requiring an immediate professional recovery solution.
Diagnosis & Evaluation
When the Iomega LinkStation RAID 5 NAS (four-disk setup) arrived at our secure cleanroom facility, we conducted a full RAID and file system diagnostic. Our findings:
- Power surge had corrupted RAID metadata, preventing proper array reconstruction.
- Filesystem corruption (EXT4/XFS) – The system could not recognize the partition structure.
- One drive contained unreadable sectors, requiring sector-by-sector imaging before recovery.
Since continued RAID rebuild attempts could permanently overwrite remaining data, we prioritized manual RAID reconstruction and file system repair.
The Recovery Process
1. Cloning & Imaging All RAID 5 Disks to Prevent Further Data Loss
To preserve all recoverable data, we:
- Created forensic sector-by-sector clones of all four NAS drives.
- Used specialized RAID recovery tools to extract readable sectors while bypassing damaged areas.
2. Manually Rebuilding the RAID 5 Array & Restoring Corrupt Metadata
Since RAID metadata was corrupted, we:
- Reconstructed the RAID 5 structure outside of the NAS system.
- Repaired missing RAID headers and partition tables.
3. Extracting & Verifying Work Documents & Photos
Once the RAID 5 structure was successfully rebuilt, we:
- Recovered all critical work documents, PDFs, and spreadsheets.
- Restored personal and professional photographs in high resolution.
- Transferred the fully restored data to a secure external backup device.
