At Exeter Data Recovery, we are the No.1 RAID data recovery specialists in Devon, with over 25 years of experience recovering data from failed software and hardware RAID systems, including Microsoft Small Business Server environments. Whether caused by failed redundancy, degraded performance, or incomplete rebuilds, we have the tools and expertise to resolve complex RAID failures and recover critical data—safely and securely.
If you are experiencing failed RAID redundancy, rebuild loops, or partially accessible data, our RAID engineers can perform a complete forensic-grade raid hard drive recovery, even when traditional backup methods have failed.
Case Summary: SBS Software RAID Failure and Rebuild Loop
In this case, a client was running Microsoft Small Business Server (SBS) on a 4-drive software-based RAID array. The client reported:
- One drive showing intermittent issues and poor performance
- Repeated RAID rebuild attempts that failed to complete
- Final system state showing “failed redundancy”
- Data partially recoverable, but essential files inaccessible
- All drives eventually removed and tested—three showing no error, one significantly slower but not flagged as failed
This type of failure is common in software-managed RAID arrays, where drive synchronisation depends on the operating system rather than dedicated RAID hardware. Inconsistencies in timing, degraded drive performance, or misalignment between data and parity can cause rebuild failures and total volume loss.
Our RAID Hard Drive Recovery Process – Step by Step
At Exeter Data Recovery, we follow a proven, non-destructive process for RAID data recovery, ensuring data integrity and maximum recovery success—even when drives appear healthy but the array will not rebuild.
Step 1: Full Forensic Imaging of All Drives
- All four drives are removed from the system and individually cloned sector-by-sector using forensic imaging equipment (e.g. DeepSpar Imager or PC-3000).
- Drives are cloned in read-only mode, with write-blocking protection, to preserve their original state.
- The slower drive is imaged with adaptive timing to avoid read failures and maximise sector recovery.
- We document:
- Sector errors
- SMART status
- Any physical read delays
⚠️ Important Note: Attempting to rebuild the array or introduce new drives without full imaging can permanently destroy valid parity and make recovery impossible.
Step 2: RAID Metadata and Configuration Analysis
- Since this is a software RAID, there is no dedicated controller metadata—RAID settings are stored in the OS or partition headers.
- Our engineers analyse the image clones to determine:
- RAID level (RAID 5 is common in 4-disk SBS setups)
- Block/stripe size (commonly 64KB or 128KB)
- Drive order and sequence
- Parity rotation algorithm
- Logical volume offset
We reconstruct the original virtual array environment using specialised tools such as UFS Explorer RAID, R-Studio Technician, and PC-3000 RAID Edition.
Step 3: Virtual Array Rebuild and Integrity Testing
- A virtual RAID array is assembled from the cloned images.
- We test multiple permutations of drive order and stripe size to achieve a configuration that restores:
- Partition tables
- File system structure (usually NTFS in SBS environments)
- User directories and shared folders
Data is tested for readability and cross-verified using known file signatures and metadata.
Step 4: Logical File System Recovery
- Once a stable array is reconstructed, we perform:
- Partition repair
- MFT (Master File Table) recovery
- Folder and file-level data reconstruction
- We prioritise recovering:
- Business-critical files
- Shared drives and documents
- Outlook PST files, database backups, and application data
In cases of partial file corruption, we rebuild fragmented files using header/footer matching and error-correction techniques.
Step 5: File Validation and Data Return
- Recovered data is verified using checksums and file integrity tests.
- Data is organised to reflect original server share structure (e.g., Users, Public, Company Data).
- Files are exported to a healthy external storage medium or to a new server environment (optional data preparation available).

Contact the RAID Recovery Experts Today
If your Microsoft Server or software RAID array has failed, is constantly attempting and failing rebuilds, or shows failed redundancy messages, do not continue rebuilding or reinitialising the volume. This may cause irreversible data loss.
