I bought an 8GB USB flash drive to use for school last August. I haven't had any problems with it until this week. I formatted it and loaned it to my boyfriend to create a factory reset file for his computer (I think he used the kind that writes a DVD file to USB to read like a DVD--I've used that kind of file before without problems). When I took it back, I reformatted it, but now my computer reads it as having a capacity of just under 1.5 MB. Yes, with an M. There are no visible files on the USB, and I tried formatting a couple more times. What happened? Can I fix this?
