🔑Encryption Guide

IODD AES256 hardware encryption guide for ST400, MINI PRO, LK100, and legacy MINI devices.

IODD AES256 hardware encryption protects the entire internal disk before the operating system can access it. This guide compares encryption support for ST400, MINI PRO, LK100, and MINI, and explains the setup order for 2nd Password, administrator access, user access, and safe disk initialization.

Hardware Model Comparison

The IODD provides robust hardware-based encryption. The following table summarizes the encryption capabilities by model:

Feature	ST400 / MINI PRO	LK100	IODD MINI
Max Password Length	38 Digits	38 Digits	16 Digits
2nd Password Support	O	O	X
Admin Mode	O	O	X
Random Keypad	O	O	O
Keep 2 Min. PW	O	O	X

ST300 Notice The ST300 model does not support hardware encryption features. For encryption support, please use the ST400, LK100, or MINI/MINI PRO series.

Core Encryption Features

IODD employs Full Disk Encryption (FDE) on a hardware basis. This ensures that the entire disk is protected, and no data can be accessed or recovered without the correct password.

Random Keypad Security For enhanced security, all encryption-related inputs utilize a Random Keypad system where the number positions change every time the screen is activated. This prevents fingerprint tracing on specific keys. Always verify the keypad layout on the screen carefully before entering or setting your password.

Data Initialization Warning Enabling or disabling the encryption feature will completely initialize (erase) all data on the disk. You must back up all critical data to a separate storage device before making any changes to encryption settings.

Incompatibility & Conflicts

• Encryption formats between IODD 2541 and ST400/LK100 are not compatible.

• Do not use IODD hardware encryption simultaneously with third-party software encryption solutions (e.g., BitLocker, VeraCrypt). Doing so may cause system instability or data corruption.

Getting Started

To use the encryption features safely, set up the 2nd Password first. It is the administrator key used during encryption initialization and when moving an encrypted disk to another ST400/LK100/MINI PRO enclosure.

Terminal Tips for Advanced Users

If you are managing drive paths or checking mount points on a Mac, you can use the following command:

    # List all connected disks to identify your IODD
    $ diskutil list
