Synology NAS (4×10TB) RAID5 Recovery in Guntur, India
Case Overview :
A 4-year-old Synology with 4×10TB HDDs (RAID5) failed in Guntur after two members began timing out during a scrub, endangering 19.3TB of engineering, finance, and media shares used across Arundelpet, Brodipet, and Lakshmipuram. Shares went offline and services stalled. Synology NAS RAID5 Recovery in Guntur began with parity-consistent workflows and No Data No Charge intake to prevent array-wide corruption.
- Brand: Synology NAS (RAID5, 4×10TB)
- Capacity: 40TB raw (approx.)
- Data Size: 19.3TB
- Success Rate: 100%
Problem Description
The NAS dashboard reported “Degraded” then multi-disk error states; hot-swaps worsened behavior. Continued access risked parity drift and filesystem damage. With audits and handovers pending, a clone-first, assemble-later approach was essential to validate stripe order and parity before any filesystem operations or mounts.
Understanding the Challenge
When multiple members destabilize, RAID5 parity becomes fragile. Recovery demands mechanical stabilization (donor head swaps where needed), firmware calibration, sector-consistent cloning with head map tuning, and a virtual RAID verifying stripe/parity prior to extraction. Filesystem repair only follows after block-level integrity passes, preserving ACLs and timestamps.
Data Recovery
Each failing member was stabilized; donor head swaps performed as indicated; firmware adaptives tuned. Sector-by-sector cloning captured healthy regions and logged marginal tracks for adaptive retries. A virtual RAID5 was assembled; stripe/parity checks passed. Extraction prioritized engineering/finance/media shares; ACLs/timestamps were validated via sample opens and permission tests.
Outcome of Data Retrieval
All 19.3TB restored with structures, permissions, and timestamps intact. Teams in Arundelpet and Lakshmipuram resumed operations promptly. Preventive policies—hot spares, staggered refresh, offsite replication, and thermal/vibration controls—fortified the environment for future quarters.
Conclusion:
Multi-disk instability is recoverable with parity discipline. Synology NAS RAID5 Recovery in Guntur proved clone-first, parity-consistent assembly preserves enterprise shares fully.
