At Exeter Data Recovery, we are the No.1 RAID data recovery specialists in the South West, trusted for over 25 years by individuals, SMEs, and enterprise clients to resolve complex storage failures. If your RAID 5 array has fallen out of sync and is showing drives as “missing” despite being physically present, or if you’ve lost data following an attempted rebuild, we have the advanced tools and deep technical expertise to recover your data safely and effectively.
We specialise in raid 5 file recovery from systems using ASUS, Intel, LSI, and other controller chipsets, with full support for manual RAID reconstruction, corrupted metadata repair, and file system restoration.
Case Scenario: RAID 5 Array Failure with ASUS RAID Controller
A client presented a RAID 5 array configured using an ASUS RAID controller. The array exhibited repeated desynchronisation during file saves, resulting in the following issues:
- Data being saved to incorrect files or directories
- Sudden data loss when attempting to save changes
- Drives reported as “missing” or “offline” despite being properly connected
- The controller requesting frequent or forced array rebuilds
- Manual drive replacement worsened the state, causing metadata mismatch and degraded state
This situation is common when a RAID controller’s metadata becomes inconsistent or corrupted, especially if a user replaces drives or attempts multiple rebuilds without validating parity integrity first. If not addressed correctly, rebuilds can overwrite valid data with corrupted or out-of-sequence parity.
Our RAID 5 File Recovery Process – Step-by-Step
At Exeter Data Recovery, we follow a professional and non-destructive workflow to recover lost data from RAID 5 arrays, even after incorrect rebuilds or controller-induced corruption.
Step 1: Diagnostic Evaluation & RAID Metadata Analysis
- All drives are physically removed and cloned using forensic-grade write-blocking hardware to ensure no changes are made to the original data.
- Using advanced tools (e.g. PC-3000 RAID Edition, UFS Explorer RAID), we analyse:
- Drive order and sequence
- Block size (typically 64KB, 128KB, etc.)
- Parity rotation pattern (left asynchronous, right synchronous, etc.)
- Controller-specific metadata headers
- Controller inconsistencies are identified, including outdated or invalid RAID table entries.
Step 2: Manual RAID Reconstruction
- A virtual RAID environment is created from the disk clones.
- Missing or misconfigured drives are reintroduced virtually, allowing for non-destructive testing of multiple array configurations.
- If one or more drives contain corrupted parity or stale data (e.g., after an improper rebuild), they are excluded or corrected using parity validation logic.
⚠️ Important Note: ASUS onboard RAID solutions often use Intel Rapid Storage Technology (RST) or Marvell-based chipsets that can silently update RAID metadata. Manual rebuilding without correct order or using the wrong disk can corrupt the array beyond logical repair. We bypass controller interference by using raw disk images for analysis.
Step 3: Logical File System Recovery
- Once a valid RAID structure is rebuilt, we scan for the original file system—commonly NTFS, exFAT, or ReFS.
- Corrupted partition tables, Master File Table (MFT) entries, and directory indexes are rebuilt.
- Lost files, including overwritten or fragmented data, are recovered using file carving and metadata reconstruction.
Step 4: File Integrity Checks and Recovery
- Recovered files are validated using:
- Checksums and hash comparisons
- Timestamp consistency
- File structure validation (especially for documents, images, and databases)
- Data is then safely transferred to a clean and verified destination drive.

Secure RAID Recovery Starts Here
If your RAID 5 array is out of sync, reporting missing drives, or demanding rebuilds after controller issues—stop all rebuild attempts immediately. Every rebuild could be overwriting valid parity data and making recovery more difficult.
