Data recovery case studies — real-world scenarios and procedures
Data recovery case studies — how the laboratory works
Below we have gathered selected case studies from our data recovery laboratory. Each case describes a real failure scenario without revealing sensitive data — client details are anonymised. All recoveries are carried out safely: first diagnostics, then a sector-by-sector copy, and only then work on the copy.
Selected case studies
- WD My Passport NVMe — complex case study — a USB-only / NVMe scenario and work in technological mode.
- Ransomware on a QNAP NAS — recovery without paying the ransom (case study) — safe handling and minimisation of overwrite risk.
- VMware / ESXi — datastore missing after restart (case) — data recovery from server infrastructure.
- Water-damaged photographer’s laptop — archive recovery (case) — work under time pressure with a safe procedure.
Why case studies help with safe recovery
- They show which user actions most often make the situation worse (formatting, CHKDSK, initialisation, rebuild).
- They help recognise symptoms and choose the right direction: HDD / SSD / RAID / flash.
- They build trust: procedures, work on a sector copy, confidentiality (NDA) and a rigorous laboratory approach.
How to read case studies without drawing the wrong conclusions
A case study should not encourage visitors to repeat the same procedure at home. Its role is to show the lab workflow: secure the medium first, create a sector copy or technological image, and only then perform the actual recovery. This matters especially with SSD/NVMe, RAID/NAS, USB-only devices and liquid damage, where one wrong step can close the door to safe recovery.
- look for a similar failure pattern, not necessarily the exact same device model,
- focus on what was done before recovery and what was deliberately avoided,
- use the case study as a decision aid: whether to stop experimenting and escalate to a professional lab.
Case studies by media type and business environment
If you want to find a comparable incident faster, jump to the right thematic cluster. This makes case studies support not only trust, but also practical triage of the failure scenario.
- HDD — clicking, drops, CRC errors, RAW volumes and read instability.
- SSD / NVMe — brick states, no detection, update-related failures and power-loss cases.
- RAID / NAS — degraded arrays, offline volumes, failed rebuilds and business incidents.
- Ransomware — safer recovery paths without paying the ransom.
- Accounting and business data — when the outage directly blocks operations and deadlines.
Want to assess your case quickly?
If the device shows failure symptoms (RAW, 0 B, CRC errors, disappearing from the system, degraded RAID), stop working and do not run “repairs” and contact the laboratory. We handle clients from all over Poland via shipping.
