5. Maintenance and Care
To ensure the longevity and optimal performance of your GIGASTONE MicroSDXC card, follow these maintenance guidelines:
- Physical Protection: The card is designed to be waterproof, shockproof, temperature-proof, and X-Ray proof. However, avoid exposing it to extreme physical stress or harsh chemicals.
- Cleanliness: Keep the metal contacts on the card clean and free from dust or debris. Use a soft, dry cloth if cleaning is necessary.
- Safe Removal: Always safely eject the memory card from your device before physically removing it to prevent data corruption.
- Buffer Memory: MicroSD cards reserve a portion of their capacity as buffer memory for firmware, applications, and software. A larger buffer memory contributes to a longer lifetime for the card. This is why the usable capacity may be slightly less than the advertised nominal capacity (e.g., a 1TB card may show around 906GB usable).

6. Troubleshooting
If you encounter issues with your GIGASTONE MicroSDXC card, consider the following:
- Card Not Recognized:
- Ensure the card is fully and correctly inserted into the device's slot.
- Restart your device.
- Try the card in another compatible device to determine if the issue is with the card or the original device.
- Check if the card requires formatting for your specific device (refer to Section 2).
- Slow Performance:
- Ensure your device supports the card's speed class (U3, V30, A1).
- Verify that the device's internal storage or processor is not bottlenecking the card's performance.
- Avoid filling the card to its absolute maximum capacity, as this can sometimes affect performance.
- Data Corruption:
- Always safely eject the card before removal.
- Ensure your device's software is up to date.
- If data corruption persists, the card may be faulty. Contact customer support.
