Data Recovery Case Log

The LEXAR Professional CF Card 128GB Compact Flash UDMA 7 is a dependable storage medium that empowers photographers and videographers to capture and store their creative endeavors. However, even the most reliable technology can experience glitches, potentially putting valuable data at risk. The story of Zero Alpha Data Recovery's successful retrieval of photos and videos from an undetectable CF card serves as a testament to the importance of professional data recovery services.

In a world where memories are often captured digitally, the ability to recover lost data can be a lifesaver. This narrative underscores the significance of selecting reputable data recovery professionals equipped with the knowledge and tools necessary to navigate the complexities of modern storage media.

The customer said they were using the card and it downloaded about half the files when it suddenly failed. They plugged it back into the camera and could still see the photos but couldn't access them. They plugged it back into the reader and could no longer detect the CF card.

We were able to put the controller chip into safe mode by shorting the test points. The SM2236 is a 4-channel CompactFlash Card Controller.

Model : SM2236-AB
Serial : (03)5526888-20101108
Firmware :
Capacity : 32 MB (65 520)

The silicon motion software can not detect this controller as its set via PATA and not USB.

SM2236G DOUBLE XOR: ECC and Data

XOR has been found but this case is unusual for the SM2236G. In most cases like this we need only one XOR to solve it, but for this case we need two XORS. One for ECC correction and one for data assembly. Creating such XOR is not an easy task.
