1. Introduction
This manual provides detailed instructions for the installation, operation, and maintenance of your G-Technology G-RAID 2 TB Dual External Hard Drive. Please read this manual thoroughly before using the device to ensure proper functionality and to prevent damage.
The G-RAID is a high-performance dual-drive storage system designed for professional content creation applications. It features multiple high-speed interfaces including eSATA, FireWire 800, and USB 2.0, offering data transfer rates exceeding 200MB/second when connected via eSATA. The unit is pre-formatted for Mac OS X systems and can be reformatted for Windows systems.
2. Safety Information
- Power Supply: Use only the power adapter supplied with the G-RAID unit. Using an incorrect power adapter may damage the device and void your warranty.
- Ventilation: Ensure adequate ventilation around the G-RAID. Do not block ventilation openings. Overheating can lead to device malfunction or data loss.
- Environment: Avoid exposing the device to extreme temperatures, humidity, dust, or direct sunlight. Operate the device in a clean, dry environment.
- Handling: Handle the G-RAID with care. Avoid dropping or subjecting it to strong impacts, as this can damage the internal hard drives.
- Disassembly: Do not attempt to disassemble or modify the G-RAID unit. This will void the warranty and may result in electric shock or damage.
- Data Backup: Regularly back up your data. While the G-RAID is a reliable storage solution, no storage device is immune to failure.

6. Operating Instructions
Using the G-RAID
- Data Transfer: Once recognized by your computer, the G-RAID functions like any other external hard drive. You can drag and drop files, use it as a target for backup software, or for direct storage in content creation applications.
- Performance: For optimal performance, especially with demanding applications like video editing, use the fastest available interface (eSATA or FireWire 800). The G-RAID supports multi-stream HDV, DVCPro HD, XDCAM HD, ProRes 422, and uncompressed SD workflows.
- RAID 0 Configuration: The G-RAID is configured as RAID 0 (striping) out of the box. This configuration maximizes speed and capacity by combining two drives into a single logical unit. Note: RAID 0 does not provide data redundancy. If one drive fails, all data on the array may be lost. Regular backups are highly recommended.
Power Management
- Power On/Off: Use the Soft Touch Power Switch on the rear panel to turn the unit on or off.
- Safe Ejection: Always safely eject or unmount the G-RAID from your operating system before powering it off or disconnecting any cables to prevent data corruption.
- Automatic Standby: The G-RAID features an automatic standby mode to conserve power when inactive for a period. It will spin up automatically when accessed.
7. Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the G-RAID. Do not use liquid cleaners or aerosols directly on the unit.
- Ventilation: Periodically check that the ventilation openings and fan are free from dust and debris to ensure proper airflow and cooling.
- Firmware Updates: Check the G-Technology website periodically for any available firmware updates for your G-RAID model. Follow the provided instructions carefully for any updates.
- Data Integrity: Regularly run disk utility tools provided by your operating system to check the health and integrity of the G-RAID.
8. Troubleshooting
If you encounter issues with your G-RAID, refer to the following common problems and solutions:
Device Not Recognized
- Check Cables: Ensure all data and power cables are securely connected to both the G-RAID and your computer.
- Power On: Verify that the G-RAID is powered on (front LED illuminated).
- Try Different Port/Cable: Test with a different USB, FireWire, or eSATA port on your computer, or try a different cable if available.
- Reboot Computer: Sometimes a simple computer restart can resolve recognition issues.
- Windows Formatting: If using Windows, ensure the drive has been properly formatted and assigned a drive letter in Disk Management.
- Drivers: For older operating systems or specific configurations, ensure necessary drivers are installed from the included CD-ROM or G-Technology website.
Slow Performance
- Interface Type: Ensure you are using the fastest available interface (eSATA or FireWire 800) for demanding tasks. USB 2.0 is significantly slower.
- Cable Quality: Use high-quality, shielded cables.
- System Resources: Close unnecessary applications on your computer that might be consuming CPU or memory resources.
- Disk Fragmentation: For Windows systems, consider defragmenting the drive if performance degrades over time (not typically necessary for Mac OS X).
Unusual Noises
- Fan Noise: The thermo-regulated fan may increase speed and noise during heavy use to cool the drives. This is normal.
- Clicking/Grinding: Persistent clicking, grinding, or scraping noises are abnormal and may indicate a failing hard drive. Immediately back up any critical data and contact G-Technology support.
