4.1 Data Transfer
- For Computers: Drag and drop files to and from the GiGimundo M20 SSD as you would with any other external drive.

4.2 4K ProRes HDR Recording with iPhone 15/16 Pro/Pro Max
The GiGimundo M20 SSD is optimized for direct 4K ProRes HDR video recording with compatible iPhones.

- Connect the M20 SSD to your iPhone via the USB-C cable.
- Open the Camera app on your iPhone.
- In the Camera settings, enable ProRes recording. You may need to navigate to Settings > Camera > Formats > Apple ProRes and toggle it on.
- Select the desired ProRes resolution and frame rate (e.g., 4K 60Hz).
- The iPhone camera interface should indicate that it is recording to "USB-C" or an external storage device.

6. Troubleshooting
6.1 SSD Not Recognized by Device
- Check Cable Connection: Ensure the USB-C cable is securely connected to both the SSD and your device.
