# Encrypted Disk Change (MINI PRO/ST/LK)

{% hint style="info" %}
**Drive Compatibility** An encrypted HDD/SSD can be moved to another ST400/LK100 device while maintaining the existing encrypted data, provided you synchronize the security settings correctly.
{% endhint %}

### Preparation

To migrate your encrypted data to a new device, you will need:

* **Existing Drive**: The original HDD/SSD containing your encrypted data.
* **Temp Drive**: A secondary or temporary drive used only for the initial setup of the new IODD.
* **New IODD**: The replacement ST400/LK100 enclosure.

{% hint style="danger" %}
**Safety First** **Do not install your Existing Drive** into the New IODD until you have completed the 2nd password configuration. This prevents any accidental data initialization during the setup phase.
{% endhint %}

***

### Migration Procedure

Follow these steps to synchronize your new hardware with the existing encryption:

#### 1. Initial Setup with the Temp Drive

Install the **Temp Drive** into your **New IODD** enclosure. This drive acts as a placeholder to safely initialize the encryption settings on the new hardware.

#### 2. Synchronize the 2nd Password

Navigate to the menu and set the **2nd Password** on the New IODD. Refer to: [2nd Password Setup Guide](/aes256-encryption-mini-pro-st-lk/admin/2nd-password.md)

{% hint style="warning" %}
**Password Consistency** You must set the **exact same 2nd password** that was used on the original device. If the drive is not recognized after the migration, you can simply re-run this process with the correct 2nd password to regain access.
{% endhint %}

#### 3. Hardware Swap

After successfully setting the 2nd password, power off the device and remove the **Temp Drive** from the enclosure.

#### 4. Final Migration

Install your **Existing Drive** into the New IODD. The device will now recognize the encryption, and you can unlock your data using your original administrator or user passwords.

***

{% hint style="info" %}
**Troubleshooting Access Issues** If your Existing Drive is not recognized after migration, it is likely that the 2nd password was entered incorrectly. In this case, re-insert the **Temp Drive**, use the **\[Chg Password]** menu in Admin mode to set the correct 2nd password, and then try the Existing Drive again.
{% endhint %}

{% hint style="warning" %}
**Encryption Prefix** Remember to enter the identification digit when prompted for a password:

* **0** + \[Admin Password]
* **1\~4** + \[User Password]
  {% endhint %}
