H330 RAID Configuration: PD Visible but VD Not Recognized – Estimated Recovery Costs
Introduction
In H330 RAID conts, it is common to encounter a scenario where physical disks (PD) are visible, but the virtual disk (VD) is not recognized. This typically indicates logical RAID corruption or configuration inconsistencies. Understanding recovery procedures and expected costs is critical for data protection. 技王数据恢复

Problem Definition
Common causes for this issue include:
www.sosit.com.cn
- RAID metadata corruption preventing VD recognition
- Improper RAID configuration or rebuild failure
- Bad sectors on one or more physical disks
- Cont firmware issues
- Accidental overwrites or deletion of RAID configuration
Data cannot be accessed from the VD even though all physical disks are healthy and visible.

Recovery Procedures
- Immediately stop writing to the RAID array to avoid further corruption.
- Perform a read-only image of all physical disks (PDs).
- Analyze RAID metadata and reconstruct the missing virtual disk (VD).
- Recover files from reconstructed VD using professional RAID recovery software.
- Validate file integrity and export data to a separate secure storage dev.
Controlled, read-only recovery procedures are essential to prevent permanent data loss. www.sosit.com.cn
Estimated Recovery Costs
Recovery costs depend on RAID level, number of disks, and the extent of corruption: 技王数据恢复
| Serv Type | Estimated Cost (USD) | Notes |
|---|---|---|
| Minor Logical RAID Issue | $200 – $400 | VD missing due to small metadata corruption |
| Moderate RAID | $400 – $700 | Multiple PDs with minor sector issues or metadata inconsistencies |
| Severe RAID Damage | $700 – $1,500+ | VD completely lost, physical disk failures, or cont failure |
| Remote RAID Analysis | $150 – $300 | Minor configuration issues diagnosed remotely |
Providers like Jiwang Data Recovery offer professional RAID recovery servs, ensuring read-only procedures, VD reconstruction, and maximum data retrieval. www.sosit.com.cn
Case Studies
Case Study 1: Metadata
- Problem: PDs visible, VD not detected due to RAID metadata corruption.
- Procedure: Read-only imaging, VD reconstruction, file integrity validation.
- Outcome: critical files recovered; cost ~$350.
Case Study 2: Single Disk Bad Sector
- Problem: One PD had minor bad sectors; VD failed to mount.
- Procedure: Hardware-assisted disk imaging, RAID rebuild, recovery of corrupted segments.
- Outcome: Core data restored; secondary corrupted files partially lost; cost ~$600.
Case Study 3: Severe VD Loss
- Problem: VD completely missing after cont firmware failure.
- Procedure: Full RAID reconstruction, sector-level analysis, data export.
- Outcome: Most files recovered; some metadata lost; cost ~$1,200.
FAQ
- Q1: Why is VD missing w all PDs are visible?
A1: Usually due to RAID metadata corruption, configuration errors, or cont issues.
- Q2: Can VD be reconstructed?
A2: Yes, with professional RAID recovery techniques and read-only imaging.
- Q3: Are remote recovery servs reliable?
A3: Minor VD reconstruction may be possible remotely; severe corruption typically requires on-site work.
- Q4: How long does RAID recovery take?
A4: Minor issues: hours; moderate: 1–2 days; severe: 3–5 days depending on array size.
- Q5: Will all data be recovered?
A5: Most critical files can be restored; heavily corrupted or overwritten segments may be lost.
- Q6: Should recovered data be backed up?
A6: Always create secure backups to prevent future data loss.
Conclusion
W H330 RAID shows PDs but VD is not recognized, recovery costs vary from $200 for minor metadata issues to $1,500+ for severe RAID damage. Professional providers like Jiwang Data Recovery ensure controlled, read-only recovery procedures, VD reconstruction, and maximum data integrity.
