FAQ

Frequently asked questions and solutions for IODD devices.

🔐 Password & Security

I entered the correct password, but it says "Incorrect."

You must enter the user identification prefix before your password.

• Admin: Enter 0 + [Your Password]. (e.g., if your password is '1234', enter '01234')

• Users: Enter 1~4 + [Your Password]. Refer to: Encryption Guide

I forgot my password. Can I recover my data?

No. It is absolutely impossible for anyone, including the manufacturer, to recover or find a forgotten password. The data is hardware-encrypted.

I forgot my password. How can I reuse the IODD?

The only way to reuse the device is to Reset Password. All existing data will be permanently lost during this process.

• 2541 : 2541 Reset Password

• MINI : MINI Reset Password

• ST400, LK100 : ST400 Reset Password

💻 Booting & Virtual Drive

The IODD will not boot from the PC.

Please refer to the Booting Error Guide for detailed troubleshooting steps.

When I mount a VHD, the mode changes to CD-MODE automatically.

This is often caused by the filename or default settings. Legacy models (2531/2541) use filename extensions like .VHD (Fixed) and .RMD (Removable) to control mode behavior. Refer to the VHD Advanced Naming Guide.

How can I unmount virtual drives?

• ST/MINI PRO: Navigate to the file and press the select key, or use the [7] eject hotkey.

• Legacy: Press and hold [7] for 3 seconds, or use the Menu -> Advanced -> Umount VHDD option.

🛠️ Hardware & Maintenance

The LCD only displays "IODD [Model Name]" and does not progress.

This indicates a system hang or corrupted firmware. Please perform a Firmware Update or use the Emergency Recovery Procedure (Section 15.2 in the Appendix).

The touch sensitivity of the buttons is poor (2541).

For older units, placing a thin piece of paper or plastic film between the internal drive and the front body (not the cover) can improve responsiveness.

The firmware update fails repeatedly.

Ensure you are using a stable USB port (rear of the PC) and have only one IODD connected. Refer to the Firmware Update Guide.
