No idea if it helps, but if you're doing it really on Win***, you have to make sure, you have administrator rights, and switch off any virus-scanners, active-protection or whatever software which could run in the background. They usually block the access to the first "tracks" of a device, without any warning ... Have the same problem, when I try to write complete sd-cards for my FPGAs, and forget about that ;-) Cheers
