SD Card & Memory Card Data Recovery
SD, microSD, CompactFlash or CFexpress card unreadable? Our Swiss laboratory recovers your photos, videos and documents with a free diagnosis in 3 hours — even from the most damaged cards.
How do we recover data from a damaged memory card?
Memory card data recovery involves extracting files stored in NAND Flash chips, even when the card is corrupted, physically broken or undetected. SD, microSD, CompactFlash and CFexpress cards are used in cameras, drones, smartphones and dashcams — each format presents specific technical challenges that our engineers master.
At our laboratory in Ins, Switzerland, we use specialised tools to access the memory chip contents directly, bypassing the controller. When necessary, we desolder the NAND chips and read them individually. For monolithic cards (a single moulded block), we solder directly onto the circuit board to bypass the controller.
Since 2006, SOS Data Recovery has processed over 11,300 media for more than 8,000 clients. Our pricing model charges 80% of the cost only if your data is recovered. We are CyberSafe certified and CyberSafe partner and rated 4.5/5 on Avis Vérifiés (249+ reviews).
What failures affect memory cards?
Recognise one of these situations? Contact us for a free diagnosis in 3 hours.
Why is your memory card corrupted or unreadable?
The card displays read errors, files are inaccessible or the file system is corrupted. Our specialised tools rebuild the data structure and recover your files.
What to do if your SD card is broken or cracked?
Bent contact, cracked or broken card. Our engineers desolder the memory chips and read them directly, bypassing the physical damage.
How to recover a card dropped in water?
Card dropped in water, exposed to rain or prolonged moisture. NAND chips often survive water damage — we desolder them and read their contents after drying and cleaning.
How to recover an accidentally formatted card?
Accidental formatting in the camera or computer. Do not write anything to the card to maximise recovery chances. Our tools rebuild the allocation table.
Why is your card no longer detected?
The card reader or device no longer recognises the card. This issue is often linked to the internal controller. Direct NAND chip reading bypasses this failure.
Can overwritten or infected data be recovered?
Files partially overwritten by new data or malware infection. The faster the intervention, the higher the recovery chances. Stop using the card immediately.
How does data recovery work?
From free diagnosis to secure delivery — a transparent 4-step process, entirely performed in our Swiss laboratory.
Free diagnosis within 3 hours
Send your media by secure post, drop it at one of our 30 collection points across Switzerland, or bring it directly to our laboratory in Ins. Our team performs a full analysis within 3 hours of receipt — free and with no commitment.
Transparent quote before any work
You receive a detailed quote outlining the type of failure, recovery chances and exact cost. You approve before any work begins. Full payment on success — only attempt costs are charged if recovery fails.
Recovery under ISO 5 laminar flow
Our technicians work under ISO 5 certified laminar flow with specialised tools (PC-3000). Your data never leaves our CyberSafe-certified and CyberSafe partner Swiss laboratory. Duration: 2 to 10 business days depending on complexity.
Secure delivery of your data
Your recovered data is delivered on a new encrypted drive, or via secure download according to your preference. Original media can be destroyed on request to guarantee confidentiality.
