I bought 5 packs of 64GB to install Linux OS images on them. When you try to upload images to them, they fail or accidentally get disabled. sensitive to connection to USB hubs. When connected to 4 different USB hubs (some powered, some not), they would disconnect or fail to complete the image transfer. Tried to reformat while connected to a USB hub and same errors. When connected directly to the computer's I/O panel on the motherboard, they stayed connected, allowing the drive to be reformatted and images loaded. That issue aside, they work and appear to be a legitimate 64GB. Just picky where it connects.
