4. Maintenance and Care
To ensure the longevity and optimal performance of your ADATA microSDXC card, follow these maintenance guidelines:
- Safe Removal: Always safely eject the card from your device before physically removing it to prevent data corruption.
- Physical Protection: Store the card in its protective case or the SD adapter when not in use to prevent physical damage to the contacts or card body.
- Environmental Protection: The card is designed to be X-ray proof, temperature proof, and magnetic resistant. However, avoid exposing it to extreme conditions unnecessarily.
- Regular Backups: Periodically back up important data from your microSD card to another storage medium (e.g., computer hard drive, cloud storage) to prevent data loss.
- Avoid Formatting: Only format the card when necessary, as formatting erases all data. If formatting is required, use your device's built-in formatting utility or a reliable computer utility.
5. Troubleshooting
If you encounter issues with your ADATA microSDXC card, consider the following troubleshooting steps:
- Card Not Recognized:
- Ensure the card is fully inserted into the slot.
- Try inserting the card into a different compatible device or using the SD adapter with a computer to rule out a device-specific issue.
- Check if the SD adapter's write-protection switch is in the "unlocked" position if using the adapter.
- Clean the gold contacts on the card with a soft, dry, lint-free cloth.
- Slow Performance:
- Ensure your device supports UHS-I speeds. Older devices may not fully utilize the card's speed capabilities.
- Avoid filling the card to its maximum capacity, as this can sometimes affect performance.
- If using for app storage, ensure your Android device is optimized for A1 performance.
- Data Corruption/Errors:
- Always safely eject the card before removal.
- Run a disk check or error-checking utility on a computer to scan for and repair bad sectors.
- If issues persist, back up any recoverable data and then format the card.
- Card Capacity Incorrect:
- Some devices or operating systems may display slightly less than the advertised capacity due to formatting overhead. This is normal.
