1. Introduction
This manual provides instructions for the Mediasonic HUR6-15 replacement top and bottom covers. These covers are specifically designed to accommodate thicker 12.5mm and 15mm 2.5-inch SATA hard drives within the Mediasonic HUR6-SU31C 2-Bay USB-C Enclosure. This product consists solely of replacement covers and is not a standalone hard drive enclosure. It is intended as an accessory to expand the compatibility of your existing HUR6-SU31C enclosure with larger capacity 2.5-inch drives.
2. Safety Information
- Ensure the HUR6-SU31C enclosure is powered off and disconnected from all cables before attempting to replace covers or install drives.
- Handle hard drives and enclosure components with care to prevent damage from static electricity.
- Use only the provided screws for installation. Using incorrect screws may damage the enclosure or drive.
- Keep small parts, such as screws and padding, out of reach of children.
3. Package Contents
Verify that all items are present in your package:
- 1x Top Replacement Cover (Grey)
- 1x Bottom Replacement Cover (Grey)

4. Setup and Installation
These covers are designed to replace the standard covers of the Mediasonic HUR6-SU31C enclosure to accommodate thicker 2.5-inch SATA hard drives (12.5mm or 15mm height).
- Prepare the Enclosure: Ensure your Mediasonic HUR6-SU31C enclosure is powered off and disconnected from your computer. Remove any existing hard drives and the original top and bottom covers from the enclosure. Refer to your HUR6-SU31C enclosure manual for detailed instructions on disassembling the unit.
- Install Hard Drives (if not already done): If you are installing new 12.5mm or 15mm 2.5-inch SATA hard drives, insert them into the drive bays of the HUR6-SU31C enclosure. Ensure they are securely connected to the SATA data and power connectors.
- Apply Padding: For optimal drive stability and vibration reduction, apply the provided adhesive padding strips to the inside of the new covers, aligning them with where the hard drive will make contact.
- Attach Replacement Covers: Carefully align the new top and bottom replacement covers with the HUR6-SU31C enclosure chassis. The covers are designed to provide additional clearance for the thicker drives.
- Secure Covers: Use the four provided mounting screws to secure the new top and bottom covers to the enclosure. Do not overtighten the screws.

5. Operating
Once the HUR6-15 replacement covers are installed and secured, the HUR6-SU31C enclosure can be operated as usual. The new covers simply provide the necessary physical clearance for thicker 2.5-inch SATA hard drives. For instructions on connecting the enclosure to your computer and managing your drives, please refer to the original Mediasonic HUR6-SU31C enclosure user manual.
6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the covers. Avoid using liquid cleaners or abrasive materials, which may damage the finish.
- Storage: If the covers are removed for any reason, store them in a clean, dry place to prevent dust accumulation or damage.
7. Troubleshooting
- Covers do not fit: Ensure you are attempting to install these covers on a Mediasonic HUR6-SU31C enclosure. These covers are specifically designed for that model. Verify that the hard drives you are using are 2.5-inch SATA drives with a height of 12.5mm or 15mm.
- Drives are loose inside: Ensure the adhesive padding strips are correctly applied to the inside of the covers to provide a snug fit for the hard drives.
- Enclosure not recognized: This issue is typically related to the main HUR6-SU31C enclosure or the hard drives themselves, not the replacement covers. Refer to the HUR6-SU31C enclosure manual for troubleshooting connectivity and drive recognition issues.
