5. Troubleshooting Common Issues
Drive Not Appearing on Windows
The G-Drive ArmorATD is pre-formatted for macOS. If you are using a Windows computer and the drive does not appear, it needs to be reformatted to an NTFS file system. This process will erase all data on the drive, so ensure no critical data is present before proceeding.
- Connect the G-Drive ArmorATD to your Windows computer.
- Open Disk Management (Right-click on 'This PC' or 'My Computer', select 'Manage', then 'Disk Management').
- Locate the G-Drive ArmorATD (it may appear as 'Unallocated Space' or with an unknown file system).
- Right-click on the drive's partition and select 'Delete Volume' (if applicable).
- Right-click on the unallocated space and select 'New Simple Volume'.
- Follow the on-screen wizard, ensuring to select NTFS as the file system and assign a drive letter.
Slow Transfer Speeds
If you experience slower than expected transfer speeds:
- Ensure you are using the provided USB-C cables, as they are optimized for the drive's performance.
- Connect the drive to a USB 3.0 (or higher) port on your computer. Older USB 2.0 ports will result in significantly slower speeds.
- Avoid transferring a large number of very small files simultaneously, as this can reduce overall transfer efficiency.
