How to install Apricorn Aegis Padlock DT

Getting started with the Padlock DT is straightforward. Follow these steps to securely set up and begin using your encrypted external drive:

• Unbox the Padlock DT and connect it to your computer using the included USB cable. Ensure the computer recognizes the device and that the drive is powered on.
• Power up the drive if required and prepare to configure your PIN. On the first use, enter a new PIN on the built-in keypad. Choose a PIN that is 4 to 32 digits long and easy for you to remember but hard for others to guess.
• Confirm your PIN by re-entering it on the keypad. This establishes your unique access credential directly on the hardware, never stored on the host system.
• Unlock and format (if desired) the drive. After successful PIN entry, the encrypted volume becomes accessible. If you intend to use the drive across multiple operating systems, you may format the unlocked volume with a cross‑platform filesystem (for example exFAT) using your OS disk utility of choice.
• Practice safe usage. Eject the drive properly after each session, and remember that losing or forgetting your PIN may require support guidance from Apricorn for recovery options. Keep your PIN confidential and avoid sharing it with others.

Frequently asked questions

• Is software required to use the Padlock DT? No. The Aegis Padlock DT uses hardware-based AES-256 encryption and a built-in PIN keypad, with no software installation required.
• How do I unlock the drive? After connecting the drive, enter your PIN on the built-in keypad to unlock the encrypted volume. The drive then behaves like a secure storage device you can read from or write to.
• Which operating systems are supported? The drive is designed to work with Windows and macOS. It appears as a secure storage device on both platforms. Linux compatibility is not officially documented, so cross-platform use should be tested if needed.
• What happens if I forget my PIN? If you forget your PIN, contact Apricorn support for guidance on recovery options. Do not attempt to bypass security or repeatedly guess beyond the allowed attempts, as this can permanently lock the device.
• Can I replace or upgrade the drive inside the Padlock DT? The Padlock DT is a self-contained encrypted drive designed for security and portability. Data protection follows the device; if you need storage expansion, you would typically migrate data by unlocking and copying to a new secure drive, following Apricorn’s guidelines for security and data management.
