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.
Backup ToGo does not support an encryption function. Use of built-in Windows encryption software BitLocker is recommended (click here to enable BitLocker encryption mechanism on Windows 10 devices).
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.
