Rescue of financial data for enterprises after being flooded
Client Background: Ms. Wang, Financial Director of a medium-sized trading company in Shanghai.
Disaster Scenario: The company's server room was flooded due to a burst water pipe from the floor above. The two hard drives in the primary financial server were completely submerged in water for over 6 hours. These drives stored the company's financial data, customer contracts, and tax documents from the past 5 years.
Recovery Challenges:
The hard drives were flooded while powered off, posing a risk of circuit board corrosion.
Data recovery required a cleanroom environment to prevent further damage to the platters.
Both drives were part of a RAID 1 array, theoretically mirroring each other, but the condition of each drive needed to be verified.
Recovery Process:
Emergency Pre-treatment: Upon receiving the drives, engineers immediately disassembled them in an ultra-clean workstation and cleaned the platters and head assemblies using specialized solutions.
Component Replacement: Both hard drives' circuit boards were found to be severely corroded. Matching replacement circuit boards were sourced from drives of the same model.
Image Creation: Professional equipment was used to create complete images of both drives, revealing that one drive's read/write heads were also damaged.
Data Reconstruction: Utilizing the intact image data combined with readable sectors from the partially damaged drive, the complete file system was successfully reconstructed.
Successful Outcome:
98.7% of the data was recovered, including all critical financial databases.
Only some temporary cache files and non-critical logs were lost.
Recovery Time: 72 hours.
Helped the company avoid approximately 2 million RMB in data loss and potential legal risks.
Client Testimonial: "When I saw water flooding into the server room, I was almost in despair. I never imagined professional recovery could achieve this level. This wasn't just data recovery; it was the recovery of our company's lifeline."
