4 Remarkable Data Recovery Cases of the Month—January’2026

Stellar began its journey with a simple yet a powerful mission—to help people recover their lost data. Each year we handle over 40,000 data recovery cases, and our team of skilled engineers maintains an outstanding 80% success rate. Serving both business and individuals across industries and we routinely tackle from simple to highly complex data loss situations. In this blog, we discuss four such challenging cases that we solved successfully.

Stellar Recovered Business Critical Data from RAID 5 Server

• Client Details: F&B Business Owner
• Drive Specifications: Three 1TB SATA drives configured in RAID 5
• Issue: Logical Complex
• Data Impacted: Accounting/ Financial Data
• Impacted File/ Database Type: .mdf, .idf, .xlsx
• Service Centre: Kolkata

Client’s Concern

When client’s RAID server failed to boot and lost access to POS records, inventory databases, and financial data, he initially approached to a local data recovery vendor for a quick fix. However, recovering data from a RAID system where data is striped across the drives requires expertise. The local vendor failed to recover data from a complex multi-disk environment, which led the client to reach out to Stellar RAID Data Recovery Services.

Our Approach

• In initial inspection we first examined all member drives to assess physical health, failure type, and RAID complexity.
• Each RAID disk is cloned sector-by-sector using specialized imaging tools to prevent further data loss.
• Experts identify critical RAID parameters such as stripe size, disk order, parity rotation, and offset.
• The RAID 5 array is virtually rebuilt in a controlled environment based on cloned image.
• The reconstructed volume is scanned to detect file system integrity and locate recoverable data.
• Business-critical files, databases, and documents are carefully extracted from the rebuilt array.
• Recovered data is verified for usability before delivery.
• The successfully recovered data is provided to the client on a safe external storage device.

• Issue: Physical Complex
• Data Impacted: Personal/ Client Data
• Impacted File/Database Types: .pdf, .png, .doc, .xls
• Service Centre: Stellar Data Recovery Pune

Client’s Concern

An external hard drive suffered a sudden drop, rendering it unresponsive. The drive contained images, e-books, videos, personal Word documents, and critical client investment details — all essential to the client. The lack of backups understandably caused panic. Fearing imminent data loss, he contacted Stellar Data Recovery’s Pune office. In cases involving internal component damage, professional Hard Disk Data Recovery services are essential to safely retrieve data from physically failed drives without causing further damage.

Our Approach

• We thoroughly inspected the drive to confirm complex physical failure (suspected head damage and bad sectors).
• The drive was opened in an ISO-certified Class 100 cleanroom.
• Damaged read/write heads were replaced using compatible donor parts sourced from an identical Samsung drive.
• A complete disk image was created using proprietary tools to capture maximum readable data while bypassing bad sectors.
