Samsung EVO SSDs are widely used in business environments, including hotels, for fast and reliable data storage. However, when an SSD is not detected in BIOS, it often indicates firmware corruption, NAND flash degradation, or controller failure, leading to data inaccessibility.
This case study details how we successfully recovered critical reception accounts data for a local hotel in Guildford from a Samsung EVO SSD, after firmware corruption made the drive undetectable by the system.
As Guildford Data Recovery, Surrey’s oldest and best data recovery company, we have 25 years of experience using firmware repair, chip-off NAND recovery, and forensic data extraction techniques to restore lost files securely and confidentially.
Samsung EVO SSD Not Detected in BIOS
A Guildford-based hotel contacted us after their Samsung EVO SSD stopped functioning, with the following issues:
- The SSD was not detected in BIOS or Windows.
- Attempts to use external USB adapters failed.
- The SSD contained vital hotel reception accounts, guest records, and booking data.
- Data recovery software could not recognize the drive.
Since continued power cycles on a failing SSD can lead to complete NAND degradation, an immediate professional recovery solution was required.
Diagnosis & Evaluation
When the Samsung EVO SSD arrived at our secure cleanroom facility, we conducted a full hardware and NAND memory diagnostic. Our findings:
- SSD firmware corruption – Preventing the SSD from initializing.
- No visible NAND flash damage – Indicating a high likelihood of successful recovery.
- Power regulation issues – The SSD was unable to receive stable voltage, preventing recognition.
Since firmware corruption prevents SSDs from being detected, we prioritized chip-level NAND recovery and firmware restoration.
The Recovery Process
1. Cleanroom SSD Disassembly & PCB Repair
To restore access to the SSD, we:
- Opened the SSD in our cleanroom.
- Tested and repaired power regulation circuits to stabilize voltage flow.
- Bypassed the faulty firmware using specialized Samsung SSD recovery tools.
2. Extracting Data Using Chip-Off NAND Recovery
Since the SSD firmware was corrupted, we:
- Removed the NAND flash memory chips from the SSD PCB.
- Used specialized NAND chip readers to extract raw data.
- Rebuilt the SSD’s file system manually to restore missing files.
3. Extracting & Verifying Hotel Reception Accounts Data
Once the SSD data was extracted, we:
- Recovered all reception accounts, guest records, and financial spreadsheets.
- Restored booking schedules, payment transactions, and invoices.
- Transferred the fully restored data to a secure external backup device.
The Results: 100% Data Recovery Success
Thanks to our firmware repair and chip-off NAND recovery techniques, we successfully recovered 100% of the hotel’s lost files, including:
✅ Reception accounts, financial records, and booking data
✅ Guest records, invoices, and reservation history
✅ Organized file structures restored for easy access
The hotel was able to resume operations without losing crucial financial records, preventing business and customer service disruptions.
