5. Maintenance and Durability
The TOUGH-G series cards are built to withstand harsh conditions. To ensure longevity and optimal performance:
- Physical Protection: The one-piece molded design eliminates fragile ribs and the write-protection switch, reducing common points of failure. This makes the card highly resistant to bending, dropping (up to 5 meters), and impact.
- Environmental Resistance: The card is waterproof (IPX8, up to 72 hours at over 15 feet depth) and dustproof (IP6X). While designed for extreme conditions, avoid unnecessary exposure to water, dust, or extreme temperatures to prolong its lifespan.
- Cleaning: If necessary, gently wipe the card with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.

6. Troubleshooting
If you encounter issues with your memory card, consider the following:
- Slow Performance: Ensure your device and card reader are UHS-II compatible to achieve maximum speeds. Older devices or readers will operate at slower UHS-I speeds.
- Card Not Recognized:
- Reinsert the card firmly into the slot.
- Try the card in another compatible device or card reader to rule out a device-specific issue.
- Ensure the card is not physically damaged.
- Data Corruption: Always safely eject the card from your computer or device before removing it. Avoid removing the card during data transfer or while the device is writing to it.
- SD Scan Utility: Sony provides an SD Scan Utility that checks the health of the card by scanning its Flash memory. This utility can help identify potential issues before they lead to data loss. It will indicate if the card is normal, close to its write cycle limit, or if no more data can be written.
