Using the SD Adapter
The included SD adapter allows you to use your Micro SD card in devices that only accept standard SD cards (e.g., some laptops, older cameras).
- Slide the Micro SD card into the designated slot on the SD adapter until it locks.
- Insert the SD adapter into the standard SD card slot of your device.
- To remove, gently pull the SD adapter out of the slot, then press the Micro SD card to release it from the adapter.
Formatting the Micro SD Card
It is recommended to format the Micro SD card before first use or if you encounter issues. Formatting erases all data on the card.
- Insert the Micro SD card into your device or a computer using the SD adapter.
- Access the storage settings or disk management utility on your device/computer.
- Select the Gigastone Micro SD card and choose the 'Format' option.
- Select the appropriate file system (e.g., FAT32 for general compatibility, exFAT for larger files/capacities if supported by your device).
- Confirm the formatting process.
Operating Instructions
Data Storage and Transfer
Once inserted and recognized by your device, the Micro SD card functions as external storage. You can save photos, videos, documents, and other files directly to it.
- Recording: For cameras, drones, and dash cams, ensure the Micro SD card is inserted before starting recording. The device will automatically save media to the card.
- Saving Files: On smartphones, tablets, or PCs, you can typically select the Micro SD card as the save location for new files or move existing files to it.
- Transferring to Computer: Insert the Micro SD card (or adapter with card) into your computer's card reader. The card will appear as a removable drive, allowing you to drag and drop files.

While durable, it is always best practice to minimize exposure to harsh conditions to prolong the card's lifespan.
Troubleshooting
Common Issues and Solutions
| Issue | Possible Cause | Solution |
|---|---|---|
| Card not recognized by device | Improper insertion, incompatible device, dirty contacts, card error. | Reinsert the card correctly. Try the card in another compatible device. Clean contacts with a soft cloth. If issues persist, try formatting (data will be lost). |
| Slow read/write speeds | Device limitations, fragmented data, card nearing end of life, insufficient buffer memory. | Ensure your device supports Class 10 speeds. Transfer files to a computer and reformat the card. Consider the buffer memory explanation below. |
| Data corruption or loss | Improper removal, power loss during write, physical damage, card error. | Always safely eject the card. Avoid removing the card during data transfer. If data is lost, recovery software may be an option, but success is not guaranteed. |
| Card shows less capacity than advertised | Operating system calculation differences, reserved space for firmware/buffer memory. | This is normal. A portion of the card's capacity is used for system files and buffer memory. For an 8GB card, usable capacity is typically around 7.4GB. |
Understanding Buffer Memory
All Micro SD cards reserve a portion of their total capacity for firmware, application data, and buffer memory. This buffer memory is crucial for the card's performance and longevity. A larger buffer memory generally contributes to a longer lifespan and more stable performance, especially during continuous write operations like video recording. Therefore, the actual usable storage capacity will be slightly less than the advertised capacity.
