![]() ![]() Many companies work collaboratively to ensure the SD standards are maintained and properly built into the technology. SD is the industry standard and it’s utilized across multiple market segments of the portable storage industry. Sellers of fake cards tend to use downgraded memory, write their own firmware or improperly use another company’s IP. Poor performing cards can contribute to data loss due to them being manufactured with low quality flash memory or poor engineering. There are many fake and poor quality imitations in the marketplace that are not designed or manufactured to the same high levels of quality that you expect from reputable brands available from the SD memory card market. Users should also consider the quality of the SD memory card. This will allow safe removal of the card and prevent any corruption errors. Therefore, it’s important to understand that it’s important to wait before ejecting the card, thereby allowing the card and device to properly complete the data transfer and writing process. Most operating systems on personal computers give the user the option to eject or request the removal of media from the host device, but industrial and non-consumer devices don’t have this option. To prevent SD memory card data loss, users should always ensure the card has finished writing data before they eject the card. Contamination of the card, file system or data due to poor handling, often created when the card comes in contact with liquids.There is further risk if the file system is not performing correctly, which may result in a data misread and either erase or overwrite the needed data. The data still exists but can’t be accessed, so the navigation path must be reset and re-mapped. Corruption of the file system, resulting in the loss of the navigation path to the data.Loss of power or a variation in power that drops below the card’s operating specification, especially when data is being written.A failure in the firmware to process or manage a command.There are many contributing factors, including but not limited to: Although some devices have flashing lights or a screen to warn the user that the card is still in a write-state, many don’t.ĭata loss can also occur from a failure in the card itself. Users who are not aware of this standard device behavior have a higher risk of failure. The most common example is when the user tries to eject the card prematurely from the host device while the card or device are still in a write-state. User error can occur because many people don’t understand that SD memory cards continue to write data to the memory location for a period of time after the user has finished what they’re doing. SD memory cards typically lose data due to user or card error. Why do SD memory cards lose data and what are the causes? Critical to using SD memory cards is knowing how to maintain strong data integrity, understanding what can create potential data loss and how to avoid it. Amazing technology, given their small footprint and the massive amount of storage SD memory cards can now provide. They are used in many different devices and applications including wireless communications, digital imaging and networking. While small and compact, SD memory cards are extraordinarily complex devices that are at the heart of our digital world.
