# Disk Assembly \[ST/LK]

### Disk Assembly Guide

Please refer to the images below and follow these steps carefully. This guide applies to **ST300, ST400, and LK100** models, which share the same exterior design and use **2.5-inch 7mm** HDD or SSDs.

***

#### 1. Position the Device

Hold the **IODD main body** and the **back cover** as shown in the picture.

* **White:** Back cover
* **Black:** Main body

***

#### 2. Remove the Rear Cover

While holding the main body firmly in place, **slide the rear cover** in the direction of the arrow.

* Push it all the way to remove it completely.
* **⚠️ Warning:** Do not apply excessive inward pressure, as this may cause damage. **Be sure to push strictly in the direction of the guide.**

#### 3. Install the Disk Drive

Install the disk in the following order:

1. **Connect the SATA port side first.** Ensure it is aligned correctly.
2. **Seat the disk** into the IODD main body securely.

#### 4. Reattach the Cover

Slide the cover back on until you hear a **"click"** sound.

**Check the Latch** Verify that the rear latch is properly engaged and the cover is flush with the body.
{% endhint %}

### What do you want to do now?

If your hardware is ready, you must initialize the disk first: [**Disk Initialization Guide**](/disk-initialization.md)

* **Use Encryption:** Learn how to secure your data with the [Encryption Guide](/aes256-encryption-mini-pro-st-lk/encryption-guide.md). (Note: **ST300** does not support encryption).
* **Use Virtual Drive:** Learn how to use the **Bootable Virtual Drive** feature. [Drive Setup](/bootable-virtual-drive/drive-setup.md)
* **Use Both Simultaneously:** To use encryption and virtual drives together, follow this order:
  1. Complete the **Encryption settings** first.
  2. Then, set up your **Bootable Virtual Drive**.

#### Verification Tool

After assembly, you can check if the drive is physically detected:

```bash
# Verify the physical disk connection
$ lsblk -d | grep -i "iodd"
```
