Inspur RAID 10 arrays are widely used in enterprise environments, offering both performance and redundancy for critical business operations. However, when a RAID 10 system starts experiencing frequent I/O errors, it often indicates sector corruption, degraded disks, or RAID inconsistencies, which can lead to data loss and system failure.
This case study details how we successfully recovered business-critical data for a large factory from an Inspur RAID 10 system running 12 x 2TB WD Red NAS hard drives, after frequent I/O errors caused major disruptions.
As Leeds Data Recovery, with 25 years of RAID and enterprise data recovery experience, we used RAID parity reconstruction, bad sector bypassing, and deep file system repair techniques to restore lost factory data.
The Challenge: RAID 10 Showing Frequent I/O Errors & Sector Corruption
A large factory contacted us after their Inspur RAID 10 system became unstable, with the following issues:
- Frequent I/O errors when accessing files or running applications.
- Slow system performance, with some files failing to open or save.
- Multiple drives showing degraded status in the RAID management interface.
- Concerns that further system use could result in complete RAID failure.
Since RAID 10 relies on both mirroring and striping, any sector corruption can spread across mirrored pairs, requiring an immediate professional recovery solution.
Diagnosis & Evaluation
When the Inspur RAID 10 array (12 x 2TB WD Red NAS drives) arrived at our cleanroom facility, we conducted a full RAID-level diagnostic. Our findings:
- Bad sectors affecting multiple drives – Causing I/O errors and slow performance.
- RAID metadata inconsistencies – Some disks had fallen out of sync, leading to read/write failures.
- File system corruption (EXT4/NTFS) – Making stored business data partially unreadable.
Since forcing a RAID rebuild could overwrite existing data, we focused on manual RAID reconstruction and data extraction to avoid further corruption.
The Recovery Process
1. Cloning & Imaging All 12 RAID 10 Drives
To preserve original data and prevent further corruption, we:
- Created forensic sector-by-sector clones of all drives.
- Used specialized imaging tools to bypass bad sectors and extract readable data.
2. Manually Rebuilding the RAID 10 Array
Since the RAID metadata was damaged, we:
- Reconstructed the RAID 10 configuration manually using forensic RAID recovery tools.
- Restored mirrored data integrity across degraded drives.
- Recovered missing file system structures and lost directory indexes.
3. Extracting & Verifying Factory Business Data
Once the RAID array was successfully rebuilt, we:
- Recovered factory operational data, including production schedules and inventory databases.
- Repaired corrupted spreadsheets and work order records.
- Transferred the fully restored data to a secure enterprise RAID storage system.
The Results: 100% Data Recovery Success
Thanks to our RAID 10 metadata repair and bad sector bypassing techniques, we successfully recovered 100% of the factory’s lost data, including:
✅ Production management and inventory tracking databases
✅ Operational schedules, business reports, and financial data
✅ Engineering designs, machine logs, and compliance documents
The factory was able to resume operations without any data loss, preventing costly downtime and production delays.
