Case Overview :

A 4.2-year-old Synology NAS with 6×6TB drives (RAID6) failed in Shillong after two members destabilized during a scrub, risking 17.8TB of engineering, finance, and media shares across Laitumkhrah, Polo, and Mawlai. Shares fell offline and services stalled. DataCare Labs initiated Synology NAS RAID6 Recovery in Shillong with parity-consistent workflows and a No Data No Charge guarantee to prevent array-wide corruption.

  • Brand: Synology NAS (RAID6, 6×6TB)
  • Capacity: 36TB raw (approx.)
  • Data Size: 17.8TB
  • Success Rate: 100%

Problem Description

The NAS dashboard reported “Degraded” then multi-disk errors; hot-swaps worsened behavior. Continued activity risked parity drift and filesystem damage. With audits and handovers pending, a member-by-member clone and virtual assembly were mandatory before any filesystem actions, ensuring clean mounts and intact permissions.

Understanding the Challenge

When multiple members falter, RAID6 integrity becomes fragile. Recovery demands mechanical stabilization (donor heads as needed), firmware calibration, sector-consistent cloning with head map tuning, and a virtual array to verify stripe/parity. Filesystem repair should proceed only after block integrity has been proven, preserving ACLs and timestamps.

Data Recovery

DataCare Labs stabilized each failing disk, performed donor head swaps where indicated, and cloned sector-by-sector with adaptive retries. A virtual RAID6 was assembled; stripe/parity checks passed. Extraction prioritized engineering/finance/media shares; ACLs and timestamps were validated via sample opens and permission tests, with integrity logs attached.

Outcome of Data Retrieval

All 17.8TB restored with correct structures, permissions, and timestamps. Teams in Laitumkhrah and Mawlai resumed operations rapidly. DataCare Labs recommended hot spares, staggered refresh, offsite replication, and thermal/vibration controls to harden Shillong infrastructure against future incidents.

Conclusion:
Multi-disk instability does not have to be catastrophic. Synology NAS RAID6 Recovery in Shillong showed DataCare Labs’ clone-first, parity-consistent assembly preserves enterprise shares fully and safely.

Call To Action

If a Synology array flags multiple disk errors in Shillong (Polo, Laitumkhrah), pause use and contact DataCare Labs for parity-safe recovery under the No Data No Charge Policy.
