The USB flash drive I bought from Tsinghua Unisplendour, once inserted into the USB port, when I open it, there is a "Disk not formatted" message. But when I format it, there is a "Windows cannot complete the format" message. Also, when I took my USB flash drive to someone else's computer to format it, it could be formatted. What is the reason for this? Oh, urgent! ! ! ! ! ! ! ! ! Hope all the experts can help.
