Western Digital denied that some of its SanDisk Pro and other external SSD fail because of a hardware problem, as stated by the head of Attingo, a data recovery company, last week. In a statement released to PetaPixel, Western Digital claimed that it ensures product quality through a thorough design for manufacturing process, adherence to IPC standards for PCB design and assembly, use of high-quality solder paste, and extensive pre-shipment testing.
