SD AND CF CARD DATA RECOVERY
Most SD and CF Cards are very similar to Flash Drives in their make up, consisting of a circuit board, controller chip and one or more NAND memory chips.
In many instances, most commonly when the controller chip has failed, the memory chips need to be removed from the circuit board and the ‘raw’
data downloaded using specialized flash recovery equipment. Once the raw data has been read, we recreate the actions of the Controller Chip algorithms using special software that
enables us to reconstruct, decrypt and recover the data.
TYPICAL PROBLEMS WITH SD AND CF CARDS INCLUDE:
Card not recognized
Zero or wrong capacity shown
Asking to be reformatted
MICRO SD CARDS
A Micro SD Card is made up of the same basic components as a standard memory card but they are all encased in plastic epoxy. While this makes them smaller and lighter,
it presents a far greater challenge to recover data when the device fails.
Data recovery from a Micro SD Card is a delicate, difficult and time-consuming process as access to the memory chips is not possible until the epoxy coating is painstakingly
removed to expose the minute electrical contacts hidden within. Once the contacts are exposed, fine wire traces need to be soldered to the intricate web of circuitry in order to
access the data stored on the memory chip.
Typical SD Card Symptoms
The Card is Write Protected
If you aren’t able to read or write data to your SD card, it’s possible the lock on the side is switched on. Most SD cards have this feature to prevent data from being overwritten. If you still can’t use the device, you’ll need to format it.
Card Cannot be Used
The ‘card cannot be used’ error message will sometimes appear when your SD card is in your camera. This is because certain devices, like mobile phones, format cards so they can only be used in one device.
If your SD card is able to write files perfectly fine, but some are unreadable, this can be resolved by using free data recovery software. This can run the risk of overwriting your SD card’s data, so you should exercise caution.
SD cards are delicate devices and often made using cheap components, so they are incredibly susceptible to physical damage. Always make sure you carefully remove the device from the connector port.
Card Runs Slowly
If the SD card is running slowly, but is still working, your best option is to back up all of your data and format it. Be careful to back up everything you need before formatting though.
