What Causes SD Card Corruption?

SD card corruption is a widespread issue because its causes are numerous. Knowing what causes SD card corruption is the first step in avoiding it and preventing your data from becoming inaccessible.

Reason of Corruption Description
🧍‍♂️ Human Error Most cases of SD card corruption are caused by improper use. For example, you should never remove an SD card while files are still being transferred to/from it. To be extra safe, turn off the device the SD card is connected to first and then remove it. It’s also a good idea to avoid allowing your SD card to run out of available storage space before moving files from it.
☣️ Viruses and Malware Viruses and malware can cause SD card corruption even when they’re not designed to do so. In an effort to spread to every connected device, they sometimes forcibly enter an SD card while it’s in use, causing other applications to fail unexpectedly. There are also strains of malware capable of scrambling the entire content of an SD card using a strong encryption algorithm to make it inaccessible without the correct decryption key, which is often sold by their creators for a hefty price.
🔨 Physical Damage For such high-capacity storage devices, SD cards can be surprisingly easily damaged. The thin plastic shell tends to chip after just a few dozen insertions, and bending it in half (and irreparably damaging the tiny flash memory chips inside) doesn’t require much force at all. While SD cards can’t be easily damaged by magnets, a strong-enough electrostatic discharge could whack electrons inside the flash chips out of place and cause data corruption.
⚙️ Manufacturing Defects There are many different SD card manufacturers, some producing highly reliable SD cards that target professional users, and others producing budget SD cards of questionable reliability. You may even stumble upon counterfeit SD cards that have been manufactured using flash memory chips that have been discarded by other manufacturers for being defective.
🕰️ Exceeded Lifespan All SD cards have a limited number of write/erase cycles because they rely on electrons passing through a very thin insulating silicon oxide barrier. Over time, electrons can become trapped inside this barrier and interfere with other electrons that are trying to pass through it. Once large enough charge is trapped, the particular flash memory cell can become unwritable/unreadable. This can happen in just a few months, but it can also happen after 10 or more years. It all depends on how much you use your SD card.

Avoid SD Card Corruption with These Tips

You can avoid SD card corruption by following the tips below:

  • Never remove your SD card while files are still being transferred to/from it.
  • Turn off your device or eject the SD card before removing it.
  • Avoid SD cards from brands with no reputation.
  • Don’t purchase heavily discounted SD cards from unauthorized sellers—they’re most likely fake.
  • Move files from your SD card before you run out of available storage space.
  • Don’t use the same SD card in multiple devices without formatting it before each use.
  • Keep your SD card away from heat, moisture, and electrostatic discharges.
  • Look out for early signs of data corruption, such as poor performance and read/write errors.
  • Avoid using very old SD cards (10+ years) for important applications.
  • Never interrupt the SD card formatting process before it completely finishes.
