How We Can Help
Flash devices like USB drives and memory cards often fail due to controller problems or broken connectors. We use direct memory reading technology (NAND Dump) to reconstruct data bit by bit, ignoring the damaged controller. Ideal for photographers and videographers who lost work material.
Common Symptoms
- Device asks to format when connecting
- Not detected by computer
- Capacity appears as 0 bytes
- Corrupted files or strange names
- Photos open halfway or with gray bands
- Broken or bent USB connector
- SD card locked or write-protected
- Accidental file deletion

USB and SD Recovery FAQ
My USB drive is physically broken. Can you recover it?
Yes, we can perform 'Chip-Off' recovery, where we remove the memory chip from the board and read it directly using professional equipment.
The SD card asks to format. Should I do it?
No! Formatting can overwrite the file system structure and make recovery more difficult. Bring it to us for a safe extraction.
