The problem I am having is that I put a flash drive in a usb port on my desktop, it is running Windows 7. Then I remove it and put it into a usb port in a usb hub attached to the laptop, running Windows XP, it is seen and read then after about a minute or two it doesn't show any of the files on it. I checked the format on it and it was formated with fat32. I put it back in the desktop and a window pops up asking me if I want to scan and fix it. Any idea what the problem is? I tried to reformat it and neither computer will reformat it. Please help as this is a problem I have never encountered before, tried to google it but, I might havetyped the problem wrong. Thank you.
