📘 Introduction
This documentation provides a comprehensive, step-by-step guide to effectively using your IODD device. While the instructions are primarily tailored for the ST/LK series, most information is applicable to the MINI series as well.
⚠️ Pre-use Checklist
To ensure stable performance and data integrity, please review these requirements:
Power Supply: Connect the IODD to a rear USB port on your PC. Laptop users should use a powered USB hub for consistent voltage.
Encryption Conflict: Hardware encryption cannot be used simultaneously with OS-level encryption (e.g., BitLocker).
Cable Length: Use a USB cable shorter than 50cm to prevent signal degradation.
Disk Compatibility:
ST300 / ST400 / LK100: 2.5-inch 7mm HDD/SSD.
2531 / 2541 (Legacy): 2.5-inch HDD/SSD up to 9.5mm.
MINI (Legacy): M.2 SATA 2242 SSD.
MINI PRO: M.2 SATA 2280 SSD.
