4. Maintenance
4.1 Battery Care
The internal Lithium Polymer battery powers the keypad. To maintain battery health:
- Regularly connect the drive to a powered USB port to ensure the battery remains charged.
- Avoid extreme temperatures, which can degrade battery performance.
4.2 Physical Care
- Keep the protective cap on the USB-C connector when not in use to prevent dust and damage.
- Handle the device carefully to avoid physical impact to the keypad or casing.
- Ensure the USB-C connector is properly aligned when inserting it into a port to prevent damage.
4.3 Data Backup
While the Aegis Secure Key provides robust security, it is good practice to regularly back up critical data to another secure location to prevent data loss from unforeseen circumstances.
5. Troubleshooting
- Drive Not Recognized:
Ensure the drive is fully inserted into the USB-C port. Verify the drive is unlocked (green LED solid). Try a different USB-C port or computer. Ensure the internal battery has sufficient charge.
- "Disk Not Ejected Correctly" Warning:
This warning may appear if the drive automatically locks due to inactivity or is physically removed without safe ejection. While generally harmless for this device, always attempt to safely eject the drive from your operating system before removal to prevent potential data issues.
- Keypad Unresponsive or Partially Working:
Ensure the battery is charged. If issues persist, contact Apricorn support. Hardware keypad failures can prevent access to data.
- Frequent Disconnections:
Check the USB-C cable and port for damage. Ensure the drive is firmly connected. If using a hub, try connecting directly to the computer. Ensure the drive's internal battery is adequately charged.
- Forgotten PIN:
Due to the hardware encryption, there is no PIN recovery mechanism. If the Administrator PIN is forgotten, the drive will need to be reset, which will erase all data. User PINs can be reset by the Administrator.
