The HC300 ECO's casing is made of at least 35% PCR* (Post-Consumer Recycled) materials, which lowers carbon emissions by 48%**, gits manufacturing process boasts significantly reduced carbon dioxide emissions, waste water, energy and helping to drive a circular economy.
*PCR refers to the process of recycling, sorting, and processing waste materials discarded by consumers, and reusing them as new raw materials. Recycled plastics such as 5-gallon water jugs etc., the pictures are for illustrative purposes only.
**This data is calculated by a third-party impartial organization, for reference only.
The HC300 ECO from ADATA is designed with the earth in mind. The HC300 ECO is designed to protect the earth, uses recycled plastics from sources such as disposable water bottles, and is FSC™ (Forest Stewardship Council) certified*. The HC300 ECO's packaging is produced from environmentally friendly paper materials. Promoting sustainable management and achieving reduction, recycling, and reuse is a milestone in fulfilling our ESG commitments.
*Using products with FSC certification ensures that they come from certified sustainable forestry, which helps protect forest ecology, biodiversity, and resources, and enables companies to fulfill their social responsibility.

1. Safely Remove: Please use the "Safely Remove Hardware" function before unplugging the hard drive to prevent data corruption.
2. Avoid Collisions and Drops: When in use, please place the hard drive on a stable surface to avoid vibrations or impacts that could damage it.
3. Prevent Overheating: Keep the hard drive well-ventilated during use and do not place it in high-temperature areas or direct sunlight.
4. Stable Power Supply: Prioritize using the USB ports on the computer's main unit and avoid using unpowered USB hubs.
5. Be Mindful of Viruses and Information Security: When using the hard drive between different computers, please use antivirus software and protect your personal data.
The reasons for an external hard drive producing unusual noises could be aging, abnormalities in the circuit board, or read/write tracks. It could also be caused by the read/write head module inside the hard drive being displaced due to impact.
If the hard drive emits metallic clicking sounds and experiences slow read speeds or computer crashes, it is recommended to immediately back up your data, unplug the hard drive's power cable, and send it for repair.
Standard plastics are generally extracted from petrochemical raw materials, while PCR materials are produced from plastic particles after recycling, sorting, crushing, screening, and washing, with different proportions of additional newly produced plastics. Products made of PCR materials have undergone strict verification and testing to ensure that the recycled plastic meet the highest quality requirements and will not affect the normal use and durability of the product.
The FSC™ or "Forest Stewardship Council" is an international forest management certification framework. This framework has established a series of standards and principles to ensure that the production and consumption of forest products such as wood and paper achieves an optimal balance of environmental, social, and economic impact. Using FSC™-certified products can ensure that these products come from certified sustainable forestry, thereby protecting the forests’ ecological environment, biodiversity, and forest resources, and help companies fulfill their social responsibilities.
PCR or "Post-Consumer Recycled" materials represent items discarded by consumers after use that are recycled, sorted, processed, and then reused as new raw materials. ADATA's HC300 ECO external HDD and UC310 ECO UFD consists of 35% PCR materials, which come from transparent 5-gallon water jugs and vehicle headlight housings. Using PCR materials in products can reduce demand for new materials, waste generation, environmental burden, energy consumption, greenhouse gas emissions, and also help promote a circular economy and realize the sustainable responsibility of corporate ESG.
