How to install StarTech.com USB 3.0 / eSATA Dual-Bay Trayless 3.5" SATA III HDD Enclosure with UASP

• Prepare your drives: Ensure you are using 3.5" SATA hard drives that are in good working order. Back up any data before installation if you are repurposing drives with existing content.
• Open the enclosure and position drives: Since the design is trayless, simply align each 3.5" drive with the corresponding bay and slide it into place until it seats securely. Confirm that the drives are fully inserted before proceeding.
• Choose your connection: Decide whether you will connect via USB 3.0 or eSATA. For USB, use a USB 3.0 cable; for eSATA, use an eSATA cable compatible with your system. If your enclosure includes a power adapter, connect it to a suitable power source as required.
• Connect to your computer: Attach the enclosure to your computer using the chosen interface. If the computer requires, power on the enclosure or ensure it receives power through the connected interface. Wait for the operating system to recognize the new storage device.
• Initialize and format (if needed): In your operating system’s disk management tool, initialize the new drives if they are not automatically detected. Create or assign partitions and format the drives with your preferred filesystem. After formatting, the drives are ready for use and can be managed through your favorite file management workflow.
• Safely eject when needed: When you are finished using the drives, use your OS’s eject or safely remove hardware feature before disconnecting the enclosure, especially if you are switching to USB for continued use or transport.
