3. Setup
3.1 Installing Hard Drives
- Gently press the front door of the enclosure to open it.
- Pull out the desired drive trays.
- For 3.5-inch HDDs, align the drive with the screw holes on the tray and secure it with the provided screws. For 2.5-inch SSDs/HDDs, use the appropriate screw holes on the tray.
- Slide the loaded trays back into the enclosure until they click into place.
- Close the front door.

3.2 Connecting to Your Computer
- Connect the power adapter to the "DC In" port on the back of the enclosure and plug it into a power outlet.
- Connect one end of the USB 3.0 cable to the "USB 3.0 Type-B" port on the enclosure and the other end to an available USB 3.0 port on your computer.
- Press the power button on the enclosure to turn it on. The LED indicators will light up.

Note: For optimal performance, ensure your computer has a USB 3.0 port. The enclosure is backward compatible with USB 2.0, but transfer speeds will be limited.
4. Operating
4.1 Understanding RAID Modes
The Yottamaster 5-Bay RAID enclosure supports multiple RAID configurations, allowing you to optimize for speed, data redundancy, or a combination of both.
| RAID Mode | Description | Minimum Drives | Benefits |
|---|---|---|---|
| RAID 0 (Striping) | Data is split into blocks and written across all drives. | 2 | Highest performance, maximum capacity. No data redundancy. |
| RAID 1 (Mirroring) | Data is duplicated on two drives. | 2 | High data redundancy. Capacity is limited to the size of one drive. |
| RAID 3 (Striping with dedicated parity) | Data is striped across drives with one dedicated parity drive. | 3 | Good performance for large files, single drive failure tolerance. |
| RAID 5 (Striping with distributed parity) | Data is striped across drives with parity information distributed among all drives. | 3 | Good balance of performance, capacity, and data redundancy (single drive failure tolerance). |
| RAID 10 (Striping of Mirrors) | Combines RAID 0 and RAID 1. Data is mirrored, then the mirrors are striped. | 4 | High performance and high data redundancy (multiple drive failure tolerance). |
| JBOD (Just a Bunch Of Disks) / SPAN | Drives are concatenated to form one large logical volume. | 2 | Maximizes capacity by combining all drives into a single volume. No redundancy. |
| CLONE (Normal/Clear) | Each drive is recognized as an independent volume. | 1 | No RAID functionality. Each drive operates independently. |
4.2 Setting RAID Mode
The RAID mode is set using the DIP switches on the back of the enclosure.
- Power off the enclosure and disconnect it from your computer.
- Locate the DIP switches on the rear panel.
- Refer to the diagram below and the table in Section 4.1 to set the switches to the desired RAID configuration.
- After setting the switches, use a small pointed object (like the provided screwdriver) to press and hold the SET button for approximately 3-5 seconds until the enclosure restarts or the LEDs flash, indicating the new configuration has been applied.
- Reconnect the enclosure to your computer and power it on.
- Important: After changing RAID modes, the drives will need to be re-initialized and formatted. This process will erase all data on the drives. Backup any important data before changing RAID modes.
Figure 4.1: DIP Switch settings for various RAID modes.
4.3 Initializing and Formatting Drives
After setting the RAID mode, the new logical volume must be initialized and formatted by your operating system.
For Windows:
- Right-click on "This PC" (or "My Computer") and select "Manage".
- In the Computer Management window, select "Disk Management" under "Storage".
- You should see the new disk listed as "Unallocated" or "Not Initialized". Right-click on it and select "Initialize Disk". Choose MBR or GPT partition style (GPT is recommended for drives larger than 2TB).
- After initialization, right-click on the unallocated space and select "New Simple Volume". Follow the wizard to format the drive with a file system (e.g., NTFS) and assign a drive letter.
For macOS:
- Open "Disk Utility" from Applications > Utilities.
- Select the Yottamaster enclosure's volume from the sidebar.
- Click "Erase" from the top menu.
- Choose a Name, Format (e.g., APFS or Mac OS Extended (Journaled)), and Scheme (GUID Partition Map). Click "Erase" to format.
For Linux:
- Use a disk management tool like GParted or
fdisk/mkfscommands to partition and format the new volume.
5. Maintenance
5.1 Cleaning
To maintain optimal performance and longevity, regularly clean the enclosure.
- Disconnect the enclosure from power and your computer before cleaning.
- Use a soft, dry cloth to wipe the exterior.
- For dust accumulation in the ventilation holes or fan, use compressed air.
- Do not use liquid cleaners or abrasive materials.
5.2 Fan Maintenance
The integrated 80mm cooling fan helps maintain optimal operating temperatures.
Figure 5.1: Internal 80mm cooling fan.
- Ensure the fan vents are not obstructed.
- If you notice increased fan noise or reduced cooling, inspect the fan for dust buildup and clean as described above.
5.3 Drive Handling
- Always safely eject or unmount the enclosure from your operating system before disconnecting the USB cable or powering off the device.
- Avoid sudden power loss to prevent data corruption.
- When replacing drives, handle them carefully to avoid static discharge or physical damage.
6. Troubleshooting
