Data recovery,
with nothing
hidden.
Public pricing, a 2-minute estimate, and your file list before any payment. Hard drives, SSDs, RAID, NAS, smartphones — analyzed in an ISO 5 cleanroom, in France. You only pay if we succeed.
Your estimate in 2 minutes
Pick your device and the symptom: price, prognosis and the immediate action to take appear at once.
We work with every profile.
One service per device, one expertise per failure.
Each device type follows a dedicated intervention protocol in our ISO 5 cleanroom. Pick yours to see the method, pricing and success rate.
Hard drive
Clicking, drop, not detected, scratched platter. Head-stack transplant and firmware rebuild. From €300 excl. VAT.
SSD & NVMe
Dead controller, corrupt firmware, soldered MacBook SSD. Reverse FTL, NAND chip-off. From €400 excl. VAT.
RAID & NAS
Degraded array, failed rebuild, ransomware. Virtual reconstruction without touching the disks. From €550 excl. VAT.
A public, fixed price list, everywhere in France.
Where most labs only quote a price after receiving the device, Dafotec has published its flat fees since 2004 — payable only if we succeed.
No data – no fee. If we fail or you decline the quote, only €25 for reconditioning and return shipping is due — the recovery fee is never charged. Prices excl. VAT.
We show the price before we touch your device, and the list of your files before we ever charge for it.— Transparency as a method, since 2004
