Case Overview :

A Hitachi Ultrastar 4TB enterprise HDD from a 2017 server failed during backup in Chennai, affecting 3.6TB of databases and archives for an office in Guindy, Teynampet, and Nungambakkam. We began Hitachi Ultrastar 4TB Enterprise HDD Recovery in Chennai using secure, server-grade imaging workflows.

  • Brand: Hitachi Ultrastar
  • Capacity: 4TB
  • Data Size: 3.6TB
  • Success Rate: 100%

Problem Description

The drive dropped from the RAID array in Adyar and began emitting repetitive spin-up/stop cycles. Attempts to rebuild the array risked overwriting undetected bad sectors, so we isolated the drive for dedicated recovery.

Understanding the Challenge

Enterprise HDDs like the Ultrastar run 24/7 under heavy loads, increasing head fatigue and firmware wear. A clean recovery requires RAID geometry awareness and firmware repair to retrieve consistent blocks.

Data Recovery

We matched and replaced the head stack, repaired corrupt firmware adaptives, and executed low-speed imaging to a secure target. The recovered image was then integrated into a virtual RAID rebuild to extract databases and archive folders without corruption.

Outcome of Data Retrieval

All business databases, documents, and historical archives were recovered and verified. RAID rebuild recommendations with staggered drive replacements were provided for data centers in Mount Road and Velachery.

Conclusion:
RAID member failures should be addressed with both mechanical precision and logical awareness. Hitachi Ultrastar 4TB Enterprise HDD Recovery in Chennai achieved complete server data restoration.
