1. Introduction
The Amazon Basics 3.5-inch SATA HDD Enclosure provides a convenient and efficient way to convert an internal 3.5-inch SATA I, SATA II, or SATA III hard disk drive (HDD) into an external USB 3.0 storage device. This enclosure is designed for tool-free installation, offering plug-and-play functionality without the need for drivers. It is ideal for data backup, storage expansion, or accessing data from old hard drives.
2. Package Contents
Please verify that all items listed below are included in your package:
- Amazon Basics 3.5-inch SATA HDD Enclosure
- AC Power Adapter (DC12V)
- USB 3.0 Cable
- Self-Adhesive Sponges (for optimal hard drive fit)
- User Manual

3. Setup and Installation
3.1. Inserting the Hard Drive
- Gently slide open the enclosure cover. The enclosure features a tool-free design, allowing the cover to slide off without screws.
- Align your 3.5-inch SATA HDD with the internal SATA data and power connectors inside the enclosure. Ensure the connectors on the HDD match those in the enclosure.
- Carefully push the HDD into the connectors until it is securely seated.
- If the hard drive feels loose, use the provided self-adhesive sponges to ensure an optimal and snug fit within the enclosure.
- Slide the enclosure cover back into place until it clicks securely.

3.2. Connecting to Your Computer
- Connect the AC power adapter to the DC12V power port on the enclosure and then plug it into a power outlet.
- Connect one end of the USB 3.0 cable to the USB 3.0 IN port on the enclosure.
- Connect the other end of the USB 3.0 cable to an available USB 3.0 port on your computer. The enclosure is backward compatible with USB 2.0 ports, but USB 3.0 is recommended for optimal transfer speeds.
- Press the power button on the enclosure to turn it on. The LED indicator light will illuminate.

4. Operating Instructions
4.1. Power On/Off
The enclosure features an on/off button. Press the button to power the device on or off. The LED indicator light will show the power status and activity. Always ensure to safely eject or unmount the hard drive from your operating system before powering off the enclosure to prevent data loss or corruption.
4.2. Data Transfer
Once connected and powered on, your computer should recognize the hard drive as an external storage device. You can then drag and drop files, perform backups, or manage data as you would with any other external drive. USB 3.0 allows for data transfer speeds up to 5 Gbps.
4.3. Hot Swappable Functionality
The enclosure supports hot-swapping, meaning you can connect or disconnect the device from your computer while the computer is running, without needing to restart. However, always ensure the hard drive is not actively transferring data and is safely ejected from your operating system before disconnecting.
5. Maintenance
To ensure the longevity and optimal performance of your enclosure and hard drive:
- Keep the enclosure clean and free from dust. Use a soft, dry cloth for cleaning.
- Avoid exposing the device to extreme temperatures or humidity.
- Do not drop or subject the enclosure to strong impacts, as this can damage the internal hard drive.
- The smooth inner surface of the enclosure is designed to protect against scratches. Ensure the hard drive is properly seated to prevent movement.
6. Troubleshooting
- Drive Not Recognized:
Ensure the power adapter is securely connected and the enclosure is powered on. Check the USB cable connection to both the enclosure and the computer. Try a different USB port on your computer. Verify that the hard drive is properly seated within the enclosure. For new hard drives, you may need to initialize and format the drive through your operating system's Disk Management (Windows) or Disk Utility (Mac OS). - Power Button Issue:
If the power button appears loose or detached, it can often be reinserted into its slot. Gently align the button with the opening and press it firmly into place. This should restore its functionality. - Slow Transfer Speeds:
Ensure you are connected to a USB 3.0 port on your computer. USB 2.0 ports will result in significantly slower speeds. Check if other USB devices are consuming bandwidth. - Enclosure Disconnects Randomly:
Ensure all cables are securely connected. Avoid excessive movement of the enclosure during operation. If using for travel, consider a more robust enclosure design that secures the drive with screws.
