Skip to content Synology NAS (4×8TB) RAID5 Recovery in Jalandhar Cantonment
Case Overview :
A 4.5-year-old Synology NAS with 4×8TB HDDs (RAID5) failed in Jalandhar Cantonment after two members began timing out during a scrub, endangering 18.2TB of engineering, finance, and media shares. Users across Cantt Market, BMC Chowk, and Model Town lost access abruptly. Synology NAS RAID5 Recovery in Jalandhar Cantonment started with parity-consistent workflows and No Data No Charge intake to avoid array-wide corruption.
- Brand: Synology NAS (RAID5, 4×8TB)
- Capacity: 32TB raw (approx.)
- Data Size: 18.2TB
- Success Rate: 100%
Problem Description
The NAS dashboard reported "Degraded" then "Multiple Disk Errors," and hot-swap attempts worsened instability. Continued use risked parity drift and filesystem corruption. With audits and project handovers pending, a member-by-member clone and virtual assembly were mandated before any filesystem action to ensure clean, permission-correct extraction.
Understanding the Challenge
When multiple members destabilize, RAID5 parity becomes fragile. Recovery requires stabilizing mechanics (donor head swaps where needed), calibrating firmware, cloning sector-consistently, and constructing a virtual RAID to validate stripe order and parity. Filesystem repair should run only after block-level integrity proves consistent, preserving ACLs and timestamps.
Data Recovery
We stabilized each drive, executed donor head swaps where required, and cloned sector-by-sector with head map tuning. A virtual RAID5 was assembled; stripe/parity checks passed. Extraction then prioritized engineering/finance/media shares; ACLs and timestamps were verified via sample opens and permission tests. Integrity logs accompanied all exports.
Outcome of Data Retrieval
All 18.2TB shares restored with structures, permissions, and timestamps intact. Teams in Cantt Market and Model Town resumed operations promptly. A preventive policy—hot spares, staggered refresh, offsite replication, and thermal/vibration checks—fortified the environment for future quarters.
Conclusion:
Multi-disk instability doesn't have to be fatal. Synology NAS RAID5 Recovery in Jalandhar Cantonment proved that clone-first, parity-consistent assembly prevents collateral damage and preserves enterprise shares fully.
