Memory card recovery in Warsaw
We recover photos, video and project files from SD, microSD, CF, CFast, XQD and CFexpress cards used in cameras, drones, recorders and professional photo/video workflows. If the card contains the only copy, stop recording and do not format it.

Flash media recovery / Warsaw laboratory
SD, microSD, CFexpress, XQD and CFast after deletion, format prompts or damaged video
When photos or recordings disappear from a memory card, the safest first move is to stop writing to it. Do not take another test photo, do not format in the camera and do not keep copying a card that slows down or disconnects.

Recovering memory-card data without risking another write
In the Dysk i Spółka laboratory we recover data from SD, microSD, CompactFlash, CFast, XQD and CFexpress media used in cameras, drones, action cameras, camcorders and recorders. We handle deleted files, in-camera formatting, RAW file systems, 0 MB symptoms, damaged connectors and monolithic flash cases.
Cards can be delivered to our Warsaw laboratory or sent by courier from anywhere in Poland. This is useful for expats, production crews, wedding photographers and companies that cannot afford extra attempts on the original card.
Supported media
Card formats we work with
microSD cards
Drones, action cameras, phones, navigation units and compact recorders.
CompactFlash
Older professional cameras and commercial photo workflows.
XQD
Fast camera media that needs careful imaging before analysis.
CFexpress
High-bitrate professional photo and video cards used in modern cameras.
CFast
Production cards from cameras where interrupted video files may need repair.
Failure symptoms
Common cases that reach the laboratory
Camera asks to format the card
The device sees the card but cannot read the file system. Stop and do not confirm the format.
Deleted photos or video
Often recoverable if the card was not used afterwards. New recordings are the main risk.
RAW or damaged file system
The computer may show RAW, missing folders, corrupted thumbnails or card errors.
Interrupted MOV, MP4 or RAW recording
The file may have missing headers, a damaged container or an incomplete video structure.
Damaged connector or cracked card
A mechanical fault can turn a logical case into a hardware recovery case if forced.
0 MB or not detected
This may point to controller failure, flash-memory degradation or communication problems.
Very slow readout
Repeated copy attempts can increase errors and reduce the amount of stable data.
Monolithic microSD or USB flash media
Some cases require laboratory-level reconstruction from flash memory rather than ordinary software.
Practical example
A camera or drone card after a format warning
Visible symptom
The camera reports a card error, the drone stopped recording, or the computer wants to format the media.
Unsafe attempts
Formatting, recording a test clip, or copying the same damaged card repeatedly can overwrite data or create new errors.
Safer route
Put the card aside, note the device model and error message, then use the case form or phone the lab before transport.
Related symptoms
If the system shows RAW or a format message, read the guides on RAW drives and format prompts before testing the original media.
Photo and video recovery details
Photo and video material needs different diagnostics than ordinary documents
RAW and JPG photos
Recovery of image files, folder structures and metadata after deletion or formatting.
MOV, MP4 and AVI video
Container repair may be needed after interrupted recording or write failure.
Drones and action cameras
Cards from mobile, outdoor and high-vibration devices after recording errors.
Professional photography
Private, wedding, event and commercial sessions where the card may hold the only copy.
Recorders and monitoring
Video continuity and playback verification matter as much as file extraction.
CFexpress, XQD and CFast
High-speed professional cards with large files and high write rates.
Laboratory process
How memory-card recovery usually proceeds
- 01
Diagnosis and risk assessment
We classify the problem: deletion, format, file-system damage, controller failure, connector damage or monolithic flash.
- 02
Imaging or controlled readout
Whenever possible, we work from a card image or a controlled laboratory read path.
- 03
Photo and video reconstruction
We recover files and repair video structures when the recording container is incomplete.
- 04
File verification
Recovered files are checked for readability, playback and priority folders.
- 05
Secure handoff
Recovered data is copied to an agreed device with confidential handling.
Confidentiality and priority
Material safety is part of the procedure
Memory cards often contain private photos, paid shoots, legal evidence or production footage. We work on copies whenever possible, protect the original card and keep the material confidential. NDA handling is available for business, media and legal cases.
Phone first if the card is cracked, wet, not detected or needed for a deadline. We will tell you how to pack it and what information to include with the case.
FAQ
FAQ - memory card recovery
The camera or computer asks to format the card. What should I do?
Do not format it. Stop using the card and report the symptoms before another write happens.
Can deleted photos be recovered?
Often yes, if the card was not used afterwards. The fewer new writes, the better the recovery options.
Will formatting help?
No. Formatting does not restore files and can remove structures needed for recovery.
What does RAW, 0 MB or very slow copying mean?
It may indicate file-system damage, controller faults or unstable flash memory.
How should I secure the card?
Stop writing, protect the connector, note the device model and ship the card safely.
SD and microSD cards: stop writing before diagnosis
After a format prompt, missing photos or interrupted recording, the card should not return to the camera, drone or recorder. New material can overwrite fragments needed for recovery.

Cards from drones, action cameras and photo cameras
For drone, GoPro and professional camera cards, tell us the device model, file format, recording mode and whether the last clip was interrupted. This information helps us choose the right reconstruction path.
