Setup
1. Inserting the Micro SD Card
Carefully insert the Gigastone Micro SD card into the designated slot on your compatible device. Ensure the card is oriented correctly to avoid damage.
2. Using the SD Adapter
If your device requires a standard SD card slot, use the included Gigastone Micro SD to SD adapter. Insert the Micro SD card into the adapter, then insert the adapter into your device. Both adapter designs function identically and provide the same high-quality experience.

3. Formatting the Micro SD Card (If Needed)
For optimal performance and compatibility, especially with dash cams and surveillance devices, formatting the Micro SD card may be necessary. Always refer to your device's user manual for specific instructions.
- For 64GB or above capacity: The default file system should be exFAT.
- For 32GB or below capacity: The default file system should be FAT32.
- If your device only supports FAT32, please format your Micro SD card to FAT32 to ensure compatibility.
Note: If your device's user manual is unavailable, contact the device manufacturer directly for supported file systems and maximum capacity.

2. Buffer Memory
All Micro SD cards reserve some buffer memory for firmware, applications, and software. A larger buffer memory generally contributes to a longer lifetime for the card. This means the usable capacity will be slightly less than the advertised capacity. For example, a 512GB card typically has a usable capacity of around 465GB to 476GB.

Troubleshooting
1. Slow Transfer Speeds
If you experience transfer speeds lower than the advertised 120MB/s write speed, consider the following:
- Device Compatibility: Ensure your device (e.g., card reader, computer port) supports USB 3.0 or higher for optimal speeds. Older USB 2.0 ports will significantly limit transfer rates.
- File System: Incorrect formatting (e.g., FAT32 for large capacities) can impact performance. Ensure the card is formatted to exFAT for capacities 64GB and above.
- File Size and Type: Transferring many small files can be slower than transferring a few large files, even if the total data size is the same.
- Background Processes: Other applications or processes running on your computer can consume system resources and affect transfer speeds.
2. Card Not Recognized
- Reinsert Card: Remove and reinsert the Micro SD card firmly into the slot.
- Check Adapter: If using an adapter, ensure the Micro SD card is properly seated within it. Try a different adapter if available.
- Test on Another Device: Try the card in a different compatible device to determine if the issue is with the card or the original device.
- Clean Contacts: Gently clean the metal contacts on the card with a soft, dry cloth.
3. Data Corruption or Errors
- Safely Eject: Always safely eject the Micro SD card from your device before removing it to prevent data corruption.
- Scan for Errors: Use your computer's disk utility tools to scan and repair any errors on the card.
- Reformat: If issues persist, reformatting the card (after backing up any recoverable data) may resolve the problem.
