Why Choose Our RAID Recovery?
RAID recovery requires deep understanding of array configurations, parity calculations, and multi-disk reconstruction. Our specialists have recovered data from over 200 RAID arrays with configurations ranging from simple RAID 1 to complex nested RAID 60 systems.
Select Your RAID Level
Different RAID configurations require specialized recovery approaches
RAID 5 (Striping + Parity)
Data + distributed parity for single drive fault tolerance
Common Failure Scenarios
Recovery Approach
Typical timeframe for RAID 5 (Striping + Parity): 10-14 days
Actual time depends on drive condition, capacity, and failure complexity
Common RAID Failure Types
Understanding your RAID failure type helps determine the recovery approach and success probability
Two or more drives in array failed simultaneously or sequentially
Critical: Never attempt rebuild if second drive failed during first rebuild. This makes recovery significantly harder and may destroy remaining data.
No data recovered = no charge guarantee
Typical Symptoms
- •RAID array shows as degraded or failed in controller
- •NAS displays "Volume Crashed" or "Critical" status
- •Multiple drives showing red/amber lights
- •Array not mounting or accessible
- •System prompts to initialize/format array
Common Causes
- •Second drive fails during rebuild of first failed drive
- •Power surge affecting multiple drives simultaneously
- •Aging drives from same batch failing around same time
- •URE (Unrecoverable Read Error) during rebuild process
- •Controller firmware bug marking good drives as failed
Professional Recovery Approach
Multiple drive failures exceed the fault tolerance of the RAID level. This is the most common RAID failure requiring professional recovery.
- STOP immediately - do not attempt rebuild with failed drives
- Image all drives including "failed" ones (often recoverable)
- Analyze drive order, stripe size, parity rotation
- Virtual array reconstruction without writing to original drives
- Extract data from reconstructed virtual array
- Even with 2 failed drives in RAID 5, partial recovery often possible

Why RAID Recovery is More Expensive Than Single Drive
Requires understanding array configuration, parity, stripe patterns
Each drive must be imaged, analyzed, and reconstructed together
Virtual reconstruction can take days with large capacity arrays
Our RAID Recovery Process
Professional 7-step process from analysis to data delivery
Bring All Drives
Bring complete RAID array with all drives in original order
What Happens:
- Bring ALL drives from array (including "failed" ones)
- Label each drive with bay/slot position
- Bring NAS device or note RAID controller model
- Document any error messages or symptoms
- Include any RAID configuration documentation
💡Important Notes
- •Critical: Drive order matters for reconstruction
- •Even "failed" drives often contain recoverable data
- •Photo of drive bays helps track original positions
Total Recovery Timeframe
Standard service: 10-18 days from drop-off to data delivery
Timeframe varies based on RAID complexity, drive count, and failure severity
Recognize RAID Failure Signs
Identify symptoms early and take correct action to maximize recovery success
Synology: "Volume Crashed"
📱Multiple drives failed or RAID degradation beyond tolerance
STOP immediately. Do not attempt repair/rebuild. Bring to lab.
Do NOT click "Repair" or "Rebuild". This will make recovery harder.
QNAP: "Volume Invalid" or "Inactive"
📱RAID configuration lost or multiple drive failures
Power off NAS. Do not reinitialize or format.
Never click "Initialize" or "Format" - this destroys data.
Degraded RAID Warning
📱One drive failed, array running on remaining drives
Do NOT rebuild. Backup immediately if possible. Bring for recovery.
Do not insert new drive and rebuild - high risk of second failure.
WD My Cloud: "RAID Not Found"
📱Controller or configuration issue
Do not factory reset. Bring device with all drives.
Factory reset will erase RAID configuration permanently.
Multiple Red/Amber Drive Lights
📱Multiple simultaneous drive failures
Power off immediately. Each minute increases damage.
Do not keep trying to power on and access data.
Seeing These Symptoms?
Every minute counts with RAID failures. Stop using immediately and contact professionals.
Critical RAID Do's & Don'ts
These mistakes can turn recoverable RAID into permanent loss. Follow these guidelines carefully.
What TO DO ✓
Stop using the RAID/NAS immediately when degraded
CRITICALContinued use on degraded array puts massive stress on remaining drives. Each read/write operation increases chance of second drive failure. Power off safely and bring to professionals.
Bring ALL drives from the array in original order
CRITICALEven "failed" drives contain critical data. Label each drive with bay/slot position. Take photos of drive arrangement before removal. Drive order is CRITICAL for reconstruction.
Document error messages and LED patterns
IMPORTANTScreenshot NAS error messages. Note which drives show red/amber lights. Document any beeping patterns. This information helps technicians diagnose faster and more accurately.
Keep the NAS device or note RAID controller model
IMPORTANTBring entire NAS for analysis. If server, note RAID controller model and firmware version. Configuration metadata stored on controller is invaluable for recovery.
Act quickly with multiple drive failures
URGENTMultiple failures require immediate professional help. Data is still there but window for recovery narrows with time. Degrading drives worsen by the hour.
Export/backup RAID configuration if accessible
IMPORTANTIf controller utility accessible, export configuration. Note RAID level, stripe size, drive order. Screenshot RAID manager. This info speeds up recovery significantly.
Golden Rule for RAID Failure
Stop immediately. Document everything. Bring all drives to professionals.RAID recovery requires specialized knowledge and tools. One wrong action destroys data permanently. First recovery attempt has highest success.
What NOT TO DO ✗
DON'T attempt RAID rebuild with multiple failed drives
CRITICALRebuild process is extremely intensive and stressful on remaining drives. If second drive failing, rebuild will fail catastrophically. Rebuild attempt destroys existing data recovery points. Professional labs work on clones, never originals.
DON'T change drive positions or bay assignments
CRITICALRAID stripe order depends on exact drive positions. Moving drives scrambles data order making reconstruction extremely difficult or impossible. Even swapping identical capacity drives is catastrophic.
DON'T reinitialize, format, or create new RAID
CRITICALInitialize/format overwrites RAID metadata and data. Creating new array destroys existing stripe configuration. These are ONE-CLICK data destruction actions. Cannot be undone.
DON'T force RAID assembly or import foreign config blindly
CRITICALForce assembly with wrong parameters corrupts data. Importing foreign config without verification can mismatch drives. These operations write to drives and change metadata permanently.
DON'T replace failed drive and rebuild immediately
CRITICALIf second drive weakened, rebuild stress will kill it mid-process. Unverified new drive could be DOA or incompatible. Rebuild with mismatched drive causes corruption. Get professional assessment first.
DON'T use consumer recovery software on RAID
HIGHConsumer tools don't understand RAID striping, parity, or multi-disk configurations. Scanning RAID as single disk corrupts stripe patterns. Professional RAID software costs $10,000+ for reason.
DON'T power cycle repeatedly trying to get access
HIGHEach power cycle stresses failing drives further. Clicking drives damage platters more with each spin-up. Failed rebuild resumes and fails again causing more damage each time.
DON'T assume RAID 5/6 will protect you during failures
IMPORTANTRAID is NOT backup. Fault tolerance only works if drives fail sequentially with rebuild in between. Simultaneous failures exceed tolerance. UREs during rebuild are common on large drives.
DON'T upgrade firmware or make changes during degradation
HIGHFirmware update during degraded state can brick controller or NAS. Any configuration changes may prevent recovery. Leave everything as-is in failed state for professionals to analyze.
DON'T wait weeks or months to seek professional help
IMPORTANTDegraded drives continue to deteriorate. Corrosion, magnetic degradation, firmware corruption worsen with time. First recovery attempt has highest success - don't waste it on DIY.
Already Made a Mistake?
Attempted rebuild and failed? Moved drives around? Clicked "Initialize"? Stop NOW. Some data may still be recoverable but success rate drops significantly with each action.
Contact Us for AssessmentRAID Rebuild is NOT Data Recovery
Rebuild is a preventive maintenance operation for healthy arrays with ONE failed drive. It is NOT a recovery method. With multiple failures or weak drives, rebuild DESTROYS DATA. Professional recovery works on clones, rebuilds work on originals - there's no undo button.
Rule: If you're unsure whether to rebuild → DON'T. Get professional assessment first.
